Part of the transaction triggers consistency?
I have a simple named cache to which I attached a trigger that publishes the object to the queue of Tibco. I do not use any transaction here. My question is could it named cache and the process of part of the same transaction trigger method, i.e. If my failure of connection of Tibco will be be save to cache or not?Lets say in the trigger process method I'm writing throw new RuntimeExcetiion() is always saved in the cache?
Hello
We use exactly the same template in our system to push messages to Tibco when caches mutate. If you throw an exception from a trigger then the underlying cache doesn't change.

Not available in the form/triggers section GETFORMATTRIB()
Hi all
I wonder why the DAL - GETFORMATTRIB() function returns nothing when used in a trigger / image of the form.
Attribute values are defined on all forms well in advance and why they cannot be made available before Gendata()? Any reason?
Thank you!
Navin
The shape attributes and metadata are part of the content of the form stored in the library resource. The trigger process is not actually load the form of the library resource and therefore doesn't have access to the content in the form. The normal procedure is that trigger decide to register the form based on your data extract and then the form is loaded in the library. After you add the form, you can then check the attributes and metadata assigned to the form.
I guess - with a few improvements - there may be some attributes that are defined in the file list form (Group) for a given form that could be accessed during the firing process, but as a general rule, no one wants that the drop in performance of the loading of the library forms that may not become part of the transaction. Therefore, all the attributes defined in the form itself will be unavailable before the outbreak.

Return the latest data of the transaction, based on the transaction dates.
Thank you I am a little dense here, and I've searched, read and tried out a few different solutions I've seen give around the place. However; I think I'm more fighting with the naming conventions and the logic of other persons requests you to mine understanding (hoping here!)
I have a huge table that contains a record for each transaction that has an effect on our inventory (yup - LARGE table!)
For a given transaction type "CHC" (fresh), I want to return the part code, the Transaction Date and the costs of Transaction for TWO LAST changes.
Because its to be used for tracking updates to the cost of the materials and further for the calculation of the continuous effect of these, I just need the two for now.
Thus,.
The table is I50F
The required columns are
I50PART - [Code part | http://forums.oracle.com/forums/]
I50TDAT - [Date of the Transaction | http://forums.oracle.com/forums/]
I50UCOST - [price changed to | http://forums.oracle.com/forums/]

I am interested in two past reviews.
It is logical that there are two records by part of output at this stage, as it is possible that the power decide they want the last 3 or 4 or whatever (I'm sure everyone has similar experiences with beancouters)
Is this A) easy and B) relatively effective. There are 2.4 million records in the table.
If I was stupid and not included is not enough information, you please poke me [metaphorically] in my eyes, and I'm going to pad a little.
Thank you very much for reading - and even more so if you can help!

How is it assistant BootCamp 6.0.1 running on El Capitan 10.11.5 installs single partition BootCamp on the disc Fusion consisting of 128 SSD part G SSD and 3 TB of HARD drive on an iMac (retina 5K, 27 inches, end of 2014), but not the part of the HARD drive?
This has two questions:
1 capacity of SSDS faster for Fusion drive has been reduced. Therefore less effective for the reader of the merger. For example if I need to create a partition of 80G for my windows bootcamp partition, only 48 G will be left in the drive of the merger.
2. ability of the bootcamp windows partition becomes very limited, cannot be greater than 120 G.
3. even when I try to fuse out of the drive of fusion in the 128 G SSD and 3 TB of HARD disk, and then run the BootCamp assistant to create the bootcamp partition start from scratch to reinstall El Capitan only on the HARD drive (without drive Fusion), it won't let me do anything, it just shows an error that says something like "a person has created additional partitions on this drive please select. another disc. But there is nothing else to choose.
Before my (5 K, 27 inches, end of 2014 retina) to El Capitan Yosemite, I was able to use the previous version of the wizard BootCamp 5.x to create the partition, bootcamp on the drive of the merger. And it will be divided in the fuser unit in two and insert the Bootcamp partition (with the size I chose, which can go up to 1 TB) between two partitions of MAC OSX.
The disk partitions resulting from it, will be the partition MAC OS x on the SSD, the partition MAC OS x on the HARD drive partition #1, partition MAC OS x on the HARD drive partition #3.
Then there is the BootCamp partition on the HARD drive partition #2.
Is there a way to get what I need?
That is what has been described in this notice of two canoes?
Installation of Windows on a Boot Camp partition on a drive of TB Fusion 3
Thank you.
After having worked on those weeks, I realized that I need very painfully (by first going back to Yosemite and bootcamp 5 to escape all the limitations of El Capitan and BootCamp 6) I want to share here. Someone at - it other smarter solutions welcome.
Note these steps and mentioned drivers only work for my version of iMAC, retina 5K late 2014. If you have other material, please search on the web to see which driver will work first. And all of these steps are destructive and assumed that you first take backup. It is only shared for interest only. Readers will have to bear your own risk.
A. take backup
1. take a backup completes my iMac Fusion Drive using Time Machine. Then restart with a Yosemite USB installation and select Terminal from the menu on the top bar.
B. fuse out of the merger in two physical disks drive: SSD + HDD
1. in the terminal, type the commands in show what the logical volume group ID and the ID of the logical Volume of the disc fusion)
Cs diskutil list
2. in the terminal, type commands for the fuse of the fuser unit and separate them to an SSD and a HARD drive. Note: All data will be destroyed in the drive of the merger. There are many articles in this community on how this could be done,
diskutil cs deleteVolume Logical Volume ID
CS diskutil remove logical Volume Group ID
This should finish within 30 minutes. If you have taken more time, this means that your reader of fusion has been altered somehow.
I hit this issue too. To use this command to remove the fusion drive hung up, and I need to do the hard to scramble a few sections of data in the hard disk partition table using the controls to tell the OSX this hard drive is a new without partitions:
Cat >/dev/random /dev/disk0 (where/dev/disk0 is the SSD)
and repeat for disk1/dev/disk1 which is the HARD drive in my case).
This command will not return anything, but expect to press Ctrl-Z to end after 1 minute.
2 create independent partitions (non-fusionend) for the installation of OSX.
Borne Terminal output, and select disk utility, in disk utility, select the drive to HARD disk (and not on the partition), you will see the error message and you will be asked if you want to fix the fuser unit, click on ignore. Then wipe the HARD drive to create a single 'extended OSX journaled"named"HARD drive".
3. Repeat step 2, and then erase the SSD drive to create a single 'extended OSX journaled"named"SSD ".
C. install on the HARD disk as drive didier autonomous not fusion.
1. go to Yosemite install screen and proceed with the installation of a clean copy of Yosemite to the iMAC. then connect you.
D. use BootCamp Yosemite f5 to install windows.
1. launch Yosemite bootcamp.
2. check the two checkboxes for creating the USB drive to install windows 7 or a later version, and to download the windows supports the Apple software. Do not click on the last box to install or remove windows pie creating real bootcamp partition again.
3. it may take several hours to complete this function of your internet b/w and also performance of your USB drive.
4. If you install Windows 7 (like me), then the downloaded drivers will not work for you, this will cause the issue of the device driver appleDSS.sys does not like this driver and others are too recent for windows 7 to use. Also, your keyboard and mouse may not work even if you try to plug in a USB external keyboard or a mouse. You need to replace the drivers downloaded by others (the Boot Camp 5.1.5769 drivers that I find in this link: Software Support of Boot Camp 5.1.5769.) (Note: this driver is material specific only works for my iMAC model). Once you have downloaded it, copy the two files in the root directory of the USB installation to replace the original ones. It's specific and material available for download somewhere on the Apple Site.
-From the Finder, delete the $WinPE$ and the Boot Camp of the FLASH PLAYER files.
-Expand the old drivers for Boot Camp 5.1.5769 (two records and another file) on your desktop.
-Copy the $WinPE$ and records of Boot Camp in the FLASH PLAYER.
5. open Boot Camp Assistant again and only select the third option, install Windows 7.
It will show you the screen to select what installation disk, select HARD drive.
Then drag the slide bar to select the size of the Bootcamp partition for windows you want, knowing that there is a restriction for windows installed using training camp on a MAC that the last byte of the BootCamp partition must reside in the first byte of the 2.2 T of each physical hard drive.
For my case, I need only 500G for bootcamp and leaving behind 1.7 to for my MAC OSX partition immediately after the bootcamp partition and an another 0.8 T MAC OSX partition after him. 1.7 TB and the partition of MAC OS x 0.8 TB well exploited in the meantime bootcamp partition, will be merged into a fusion drive by Bootcamp. Thus, you will end up with total 2.5 TB of disk space in a logical drive - fuser.
Go to this link for more details on this subject: n-on-a-3-tb-fusion-drive http://twocanoes.com/winclone/support/installing-windows-on-a-boot-camp-partitio
6. continue the process to partition the hard drive, then it will restart automatically in windows installation mode, install windows.
7. once the installation is complete, check that windows is functioning correctly.
E. Si you want to upgrade to windows 10 Windows 7.
1 if you plan to upgrade to windows 10, you'll find that the windows IE v.8 7 is no longer works and had many problems to load the page. Then when you try to download the latest version of Internet Explorer, you get an error that you need at least windows 7 SP1 to support the last IE. Life is too complicated, just download the google Chrome browser, then search for download windows 10 and then run the Microsoft valuation tool to upgrade.
2 but before upgrade you, unplug all your MAC USB drives, otherwise, you will find that, after having spent an hour downloading the windows 10 software, the upgrade will fail with the error "/ dynamicupdate...» ». It is an inexplicable mistake that no one seems to understand why. There are articles with proven results that the removal of all USB drives before running the windows 10 upgrade tool will correct this problem.
F. reinstall OSX El Capitan
Once your target windows system (if windows 7, windows 8 or windows 10) works very well. You can continue to create again your Fusion drive and reinstall OSX El Capitan.
1. Insert the install of OSX Yosemite rear USB to the iMAC, and then select Restart Windows, or stop, and then turn the MAC once again.
2. When you hear the ringing tone, press on and hold down the option key for 10 seconds. Then you release.
3. on the selection screen, select start Yosemite OSX install drive.
4. after starting, do not proceed to install OSX El Capitan again. But select Terminal from the menu bar.
5. in the terminal, type the command 'diskutil list cs' and you should see nothing to prove that there are no existing fusion drive yet.
6 type the 'diskutil list' command to list all disks and partitions.
The SSD has two partitions, the/dev/disk0s1 of EFI (209 MB) partition and the other/dev/disk0s2 of OSX partition we created in step B above, called SSD around 121 G.
The HARD drive has two partitions, the/dev/disk1s1 of EFI (209 MB) partition and the other/dev/disk1s2 of OSX partition we created in step B above, called SSD.
G. delete the logical storage of nucleus on the HARD disk drive and it refuses with the DSS to form a merger with faster performance disc
1. Insert the install of OSX El Capitan rear USB to the iMAC, and then select Restart Windows, or stop, and then turn the MAC once again.
2. When you hear the ringing tone, press on and hold down the option key for 10 seconds. Then you release.
3. on the selection screen, select start Yosemite OSX install drive.
4. after starting, do not proceed to install OSX El Capitan again. But select Terminal from the menu bar.
5. in the terminal, type orders for (to show what are the logical volume group ID and the ID of the logical Volume of the logical drive). You should see the logical volume to basic storage group created using two partitions on the hard drive, 1.7 TB and TB 0.8 created when we run the Yosemite Bootcamp to install windows.
Cs diskutil list
6. in the terminal, type commands to delete logical drives from basic storage. Note: All data will be destroyed in the logical drive.
diskutil cs deleteVolume Logical Volume ID
CS diskutil remove logical Volume Group ID
7. tap "diskutil list" command lists all the resulting partitions. You should see that the HARD drive has the following partitions.
/ dev/disk0 (internal, physical):
#: NAME SIZE TYPE IDENTIFIER
0: GUID_partition_scheme * GB 121,3 disk0
1: disk0s1 EFI EFI 209.7 MB
2: Apple_HFS GB SSD 121.0 disk0s2
/ dev/disk1 (internal, physical):
#: NAME SIZE TYPE IDENTIFIER
0: GUID_partition_scheme * 3.0 to disk1
1: EFI EFI 209.7 MB disk1s1
2: Apple_HFS 1.7 Untitled TB disk1s2
3: disk1s3 Apple_Boot Recovery 650.0 MB HD
4: Microsoft database BOOTCAMP 503.0 GB disk1s4
5: Apple_HFS 801,4 Untitled GB disk1s5
8 type the following commands to create the logical volumes group, named "myLVG" (or the name) of fuser using the usable for OSX to the SSD and HDD partitions.
diskutil cs to create "myLVG" disk0s2 disk1s2 disk1s5
Note: Mark the group id of logical volume shown in the results.
In my case, I want to book the last partition as standalone partition disk1s5 no-fusionend, so I can use it to raise the back, or format it in FAT32 to allow the exchange of data between the MAC and boot camp.
So, I do not understand this last partition in the drive of the merger. in my case, the command that I used is: diskutil cs to create "myLVG" disk0s2 disk1s2
9 create logical volumes named "Macintosh HD" (or you call it) on the logical volume group we just created for the reader of the merger.
diskutil createvolume logical volume group ID jhfs cs + 'Macintosh HD' 100%
10 command "diskutil cs type list" to check the resulting fusion drive created.

11 exit the terminal, go back to OSX El Capitan install screen and select the name of the fuser unit 'Macintosh HD' proceed to begin the installation of the os x for installation.
12. There will be a step in the installation ask you if you want to configure as a new computer, or restore from a time machine previous backup. Make your own choices it accordingly.
13 once OSX El Capitan has been installed and you have finished restoring the data and custom configurations, you can enter the application of preferences to check if you see the icon of the "Startup" disk", and if you choose Startup BootCamp in the next reboot, you should be able to boot up to Windows without pressing and holding the button option when reboot and choose to start windows manually. Also, in windows, you should be able to click on the bootcamp Control Panel and select for a startup to OSX on the next reboot.
14. one thing to be aware, if you install bootcamp in this way, the boot camp and the GUI utility disk in OSX El Capitan will not be able to adjust your settings. This means, if you need to touch anything or to readjust the size of the partition, you will need to do it again in step A. Alternatively, some how to get started with installing Mac OSX Yosemite USB, then adjust the partitions using similar commands shown in this article or other articles in this community.
15. yet once please take personal responsibility on damage if you follow the instructions in this article.

Why control statements such a ROLLBACK or COMMIT of the Transaction are not written in the trigger?
Hello worldWhy the ROLLBACK statement or COMMIT are not allowed in the trigger? and if I then use this problem may happen?
IndiMinds wrote:
Hello world
Why the ROLLBACK statement or COMMIT are not allowed in the trigger? and if I then use this problem may happen?
Because a trigger is NOT a transaction. This is a SINGLE STATEMENT, which is part of another transaction.
What is the problem? Well, if the trigger does not use the pragma AUTONOMOUS_TRANSACTION to the 'problem' that occurs is an Oracle exception, since you cannot use commit or rollback in the standard triggers.
If a trigger contained a VALIDATION you wouldn't be able to write a transaction that contained multiple measures correctly.
What happens if you insert rows in multiple tables and you want to perform a COMMIT ONLY if all three insertions succeed?
This is not possible if one of the tables had a trigger with a posting in it.
What do you want to learn more about?

How the DDL triggers AFTER CHANGE of work?
I thought that this general framework for DDL triggers AFTER WHAT ALTER has been like that:
-Implicit VALIDATION before the DDL statement (here: ALTER TABLE)
-DDL statement
-Implicit VALIDATION after DDL statement (here: ALTER TABLE)
-AFTER ALTER DDL trigger fires
And I also thought that everything is inside that trigger would be 'new' code as introduced by the ALTER TABLE DDL. But it looks like I'm missing something about this situation because the trigger next dbms_metadata.get_ddl procedure and seeing 'old' DDL code (before the ALTER TABLE statement).
What Miss me? Could you give me some advice about this behavior? If I shouldn't expect returned DDL 'current' so why should I not?
Thank you
/ * everything is done in the SCOTT schema * /.
create table y (col1 varchar2 (5));
create table t (dt date default sysdate, d varchar2 (4000));
create or replace trigger trg
After ON ALTER scott. SCHEMA
declare
v_d varchar2 (4000);
Start
Select cast (dbms_metadata.get_ddl ('TABLE', sys.dictionary_obj_name, sys.dictionary_obj_owner) as varchar2 (4000))
in v_d
Double;
insert into t (d) values (v_d);
end;
ALTER table add col2 int;
Select * from t; -This is the 'old' DOF with only col1
I understand the transaction consistent reading, and it would work if second implicit validation had not been published before a trigger has been activated... the question is: is this second implicit validation has published in the above situation or I'm wrong about this, and commit the transaction started by first implicit included relaxation itself, and after he performed the second commit implicit came into play...
It looks like this for me, but I have not found anything in the doc Oracle stating explicitly that this is the case... Could you confirm?
Hmmm - I found it in the section client events of the doc PL/SQL language
http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/triggers.htm#g1722272
The
LOGONevent starts a separate transaction and undertakes after firing the triggers. All the other events fire in the existing user transaction.Is the same with the AFTER DDL event where you thought to try this one.
Why do you need the DOF immediately after it happens?
Just capture the same and information of interest to a table. Then, later, asynchronously, run a job to get the DDL or everything that you need. The only "gotcha" If several ddl statements are issued against the table and you needed every one of them for some reason any. Not sure why you would need for each change.

The report of the following
V$SYSSTATstatistics should be close to a:ratio = transaction tables consistent reads - undo records applied / transaction tables consistent read rollbacks
And the recommendation is that the recommended solution is to use automatic undo management...
We are in automatic cancellation, but the ratio is 38:
SQL > show Cancel parameter
VALUE OF TYPE NAME
------------------------------------ ----------- --------
UNDO_MANAGEMENT string AUTO
SELECT name, value of V$ SYSSTAT whose name in ("transaction tables consistent reads - undo records applied",
("tables of compatible transactions read restorations")
NAME VALUE ---------------------------------------------------------------- ---------------------------------------
transaction tables consistent reads - undo records applied 38 operating tables consistent read recommitments 1 2 selected lines
So, what would be the reasons and the solution?
Thank you.
This is a good demonstration of why it's a bad idea to blindly follow the ratios.
Once since your instance starts, you had to use 38 undo records to discover the time of validation of a specific transaction. The performance impact of that verification is virtually invisible - worst case, it is you read 38 undo disk blocks to get the necessary information. All you have is an example where a query ran long enough so that a few hundred to a few thousands of transactions were hiding at the time of a transaction that committed at the same time that the query started - try to 'solve the problem' is a waste of time.

How to identify the seeded triggers
Please let me know if there is a way to identify all the triggers on the tables of seeds sown that are created as part of the installation of database excluding custom triggers. All documentation would be a great help. ETRM.Oracle.com, only the indexes, constraints, and the columns are disclosed in the documentation. No information about triggers?
Custom triggers must be named XX - something, but it is not enforced.
Thus, standard seeded triggers would not named XX - something...

How to stop the transaction rollback
Hello
I created a bpel process that will make the PB data insertion, but I get the below error while inserting data. can someone please resolve this problem:
Error log:

To resolve this issue, go to the deployments on the weblogic console and open DBAdapter. Go to the Connection - Pool of outbound connections where the jndi is configured to talk to the jdbc data source.
Expand the javax.resource.cci.ConnectionFactory, and then select the case of connection.
There you can see that the name of data source is configured in the dataSourceName row while it must be configured in the xaDataSourceName line. This is because the data source, you must have defined as XA (confirmed by going on the transaction tab in jdbc configuration)Thank you

Once again the partial triggers
Hi all
I am very new to J2EE and ADF, and the design of a web page in which there are a few areas of input text and a two tables on Oracle JDeveloper and ADF 11 g. I implemented partial triggers on the table and a box of text giving the reference to one buttons and define this same button as partialSubmit = 'true '.
However when I press the command button that refreshes the table, I noticed that all the text entry boxes, menu Bar call it accessor functions Set the bean managed as well as the table is refreshed.
I read the lifecycle JSF, and ADF but I'm still not clear as to why all values are preparing or in short, the part of the life cycle when the partialSubmit is set to true and I hope that the table and the input text box should be defined or a part of the life cycle.
I'm going wrong anywhere.
Any help would be much appreciated.
Thanking you,
RohitDear Sir
This is normal behavior, all the setters will be drawn, but it dosent means that it is an update of the entire page.

[CS5] The transaction level undiminished after processing the order
I'm working on a plugin that will split a document into several other documents, each containing one or more of the original pages. We work in CS2 and toward the top, but something changed in CS5 and now I have a problem I do not know how to handle.
The plug-in basically follow this procedure for each set of pages:
- Save a copy of the original document (IDocumentCommands::SaveACopy)
- Open the copy (IDocumentCommands::Open)
- Remove unwanted copying (kDeletePageCmdBoss) pages
- Save and close the copy (IDocumentCommands::Save/Close)
All this is done in an ApplyDialogFields controller method dialog box.
After treatment of the delete command I see the level of transactions copy of database > 0, which causes InDesign enter protection stop once the plug-in tries to save the document. Wrap the kDeletePageCmdBoss in a command sequence solves the problem of transaction level (but it seems that it should not be necessary?), but ID always stop when the document is closed with the message "CloseDocCmd - document is always referenced! Stop protection will follow. " The same thing will happen if I let the command entirely.
It seems that there is another transformation happening in an idle task because when I remove the narrow part of the function I see the document to save a little when my function is completed, and after that I can close the hand without problem.
There seems to be a fairly simple procedure, but there is a subtlety on the processing of the order, I'm missing. Anyone have any ideas?
Ah, is that I asked this question a long time back and got a response. Wrap the commands in a sequence of self-canceling seems to have solved the problem. I also need to close all presentations of document with IPresentationList::CloseAllPresentations before scheduling a closing order, otherwise, I'd get a 'always referenced document' say.

What persistence tool is better for the purposes of consistency?
What persistence tool is better for the purposes of consistency? TopLink and Hibernate?
What are the advantage and disadvantage of using?
Thank youTopLink Essentials, as a product of JBoss Hibernate is a framework of persistence object / relational open-source or layer is used in Java applications. While both products strives to offer a non-intrusive, highly flexible and powerful solution there are a of the key differences.
* TopLink Essentials, derived from Oracle TopLink has been in production Java applications scale for large scale deployments and transaction volumes for more than a decade. This reliability in conjunction with a set of features has evolved through close partnerships with customers led to it a excellent performance and scaling of the solution of persistence as offering rich flexibility to configure mappings and customize the runtime behavior in support of a wide variety of database and application deployments. Customers with a certain degree of complexity in the domain model or the relationship patterns, especially where change the schema is not an option, will benefit from the flexibility and the character experienced TopLink.
* TopLink caching solution is based on caching the entity mapped instead of breaking down the data in raw art works. This storage in the format required by the application provides huge benefits in most usage scenarios. In addition, the TopLink cache is very flexible in its configuration and its control by entity type.
TopLink society is open to a friendly match with the forums without restrictions served by experienced and personal management development who has been with the product throughout its existence. Offers support services and Oracle TopLink to backup are qualified and offer global coverage.

Moving forward this project open source will continue to innovate on the basis of contributions from Oracle, Sun and others.
Help of TopLink Essentials will provide you with a rich ORM solution based on JPA standard. It will allow you also to seamlessly switch to offering of Oracle TopLink and benefit from many advanced ORM features. -
Is shuttle - possible to print values in the second part of the shuttle
Shuttle took 2. parts. Is it possible to also load values iin database part of the shuttle at the beginning? For example the user sees in the first part of the books of the shuttle of database he loves, and in the second part of the shuttle books that he dislikes database. It could pass the books from one to the other part of the shuttle. Is this possible?Hello
I set up a page the demo of the functionality you need: [http://htmldb.oracle.com/pls/otn/f?p=22619:4]
This is based on the following tables:
EMP
EMPNO pk
ENAMEBOOKS
BOOK_ID pk
BOOK_NAMEEMP_BOOKS
EMP_BOOK_ID pk
EMPNO fk
FK BOOK_ID
DATE_OUTWhat I did is:
1 created a Select list with Submit called P4_EMPNO to allow you to choose an employee. The SQL code for this is:
SELECT ENAME d, EMPNO r FROM EMP ORDER BY 1I have disabled the use of null values or extra.
2 created a calculation before header which is subordinated to the P4_EMPNO = NULL, makes:
SELECT EMPNO FROM EMP WHERE ENAME = (SELECT MIN(ENAME) FROM EMP)This just ensures that P4_EMPNO has a selected value when the page is loaded for the first time.
3 created a shuttle component called P4_BOOKS that has a SQL query to:
SELECT BOOK_NAME d, BOOK_ID r FROM BOOKSNote that I list all THE books here
4 created a PL/SQL process that runs without condition "on the load - before the heading" with the following code:
DECLARE vBOOKS VARCHAR2(100); vSEP VARCHAR2(1); BEGIN vBOOKS := ''; FOR C IN (SELECT BOOK_ID FROM EMP_BOOKS WHERE EMPNO = :P4_EMPNO) LOOP vBOOKS := vBOOKS || vSEP || C.BOOK_ID; vSEP := ':'; END LOOP; :P4_BOOKS := vBOOKS; END;This creates a string delimited by colon BOOK_ID values already selected for the current user and sets this string P4_BOOKS. The BOOK_IDs in this string, then say the features of the shuttle to move the items in the list on the right - then, all that is left in the list on the left is not selected for the user (so is your NOT IN)
5. I have a button on the page called P4_SUBMIT_BUTTON that submits the page and redirects to page 4
6 - Finally, I have a PL/SQL process that runs on submit, triggered by the submit button and has the following code:
BEGIN DELETE FROM EMP_BOOKS WHERE EMPNO = :P4_EMPNO AND ':' || :P4_BOOKS || ':' NOT LIKE '%:' || BOOK_ID || ':%'; INSERT INTO EMP_BOOKS (EMPNO, BOOK_ID, DATE_OUT) SELECT :P4_EMPNO, BOOK_ID, SYSDATE FROM BOOKS WHERE ':' || :P4_BOOKS || ':' LIKE '%:' || BOOK_ID || ':%' AND BOOK_ID NOT IN (SELECT BOOK_ID FROM EMP_BOOKS WHERE EMPNO = :P4_EMPNO); END;It removes the books of the EMP_BOOKS table for the employee, where they have been deselected (that is to say, inserted in the list on the left). It inserts then the books in the EMP_BOOKS table for the employee where the books appear in the right list BUT not included in the table EMP_BOOKS.
And that's all!

How to select a part of the message under macOS Sierra?
In previous versions of Mac OS x, I was able to select a part of the message (text / iMessage) in the Messages application. Now, if I try to do the same, Tapback is enabled. It's really annoying, as I often have to copy the entire message body, paste into an editor and then to do the editing.
Which should not happen if you simply select the text of the message by double-clicking or click-and - drag. That action works the same way it always has.
Tapback happen if you press and hold - in other words, if do not quickly move the cursor.
If you are still unable to work, please review your Trackpad preferences. Maybe change a setting arbitrary will correct what you are experiencing. Check accessibility > mouse and Trackpad in the same way: change a setting to determine if what it fixes.
