How to check account between master and detail?
I have one main entry with a count field that is supposed to represent the number of records in detail. Is it possible to write a single query that can verify that these counts are synchronized?My simple example below should, I hope, give an idea of what I am trying to accomplish.
Select masterid, mastercount, count (*) detailcount
master, detail
where masterid = detailid
Masterid, mastercount;
Thank you!
Echoing to the "Yuck" comment, you should be able to do something like
SELECT m.masterID,
m.masterCount,
(SELECT COUNT(*)
FROM detail d
WHERE d.masterID = m.masterID) detailCount
FROM master m
or
SELECT m.masterID,
m.masterCount,
d.detailCount
FROM master m,
(SELECT masterID, COUNT(*)
FROM detail
GROUP BY masterID) d
WHERE m.masterID = d.masterID

LR 4.2 - How to compare the evidence master and soft copy?
Hi all
I would like to use the audit function in LR 4.2 to preview the print output and I would use it to apply corrections to the images before they are printed, in order looks like I meant originally look like them, but I'm having problems, possibly caused by the workflow used (I'm not a pro, but my environment is calibrated correctly).
My workflow is:
1. I have import all photos and apply some changes so that the photos look like I want them to be (it's the master)
2. as I want to print them, I use the audit function and load the target profile with which I create a copy of fresh evidence. Sometimes, I noticed that the differences between master and soft copy of evidence are quite dramatic, especially regarding the contrast, color and sometimes about the brightness brightness.
3. my goal now is to adapt the image video evidence so that it looks like the control (as I wanted the photo to look like), but I can't find a good way to do it, because:
-I can't find a (semi-) automated in order to adapt to the soft proof copy so that it "looks like" the master copy
-in the develop module, I can't find a way to display the master foto both the soft proof copy in addition to each other to compare, to apply the changes to the copy of fresh evidence only so that it 'looks' like the master.
The only way I have found so far is to move bewteen back copy of master and soft proof to compare (to be able to apply the necessary changes to the copy of soft proof), but it's quite painful, as the photos do not load immediately, but there are always a few seconds and I have to 'remember' how the captain looks like.
I don't know if I'm doing something terribly wrong, but unfortunately I have not found answers to this question so far, that's why I write here.
Hope you can point me to a solution,
Kind regards

Never activate with your choice of output profile (this can include checking a web output colourspace as sRGB).
Press on Y to show a split before and after the point of view (if your toolbar is not open, press T to open - this gives different kinds of split view options).
You will now see a comparison on appearances soundproof and sound-proof of this image.
If you develop all the adaptation of this mode, for example to make these two more similar appearances, you are prompted to create a copy (virtual) checking if necessary - that can store these corrective adjustments regardless the main adjustments.
The before and after view then goes to see a comparison between your image (shown without ever) start against your explosion-proof version fitted print (shown with never).

Dev 6i, 8i DB win 7,.
Hello
,
I have two blocks of data (master and detail), the master has a piece of text with a lov, I choose the lov and go to the retail block,
related article in the retail block is assigned the value of the master element. ,
what I want is to record the detail without a master, I did not need to register all of the values in the master, I just need him to get the value of the control text element in
in the field of retail?
How to do?
Thank you
I want all the features of master blocks / detail, I want to ask the captain to recover its data and detail data.
I want to ask the retail block,
There's something I've done, but I don't know if there is something wrong with it.
I created a "Sur-Insert" trigger on the main block and wrote "Null" inside, is there something wrong
With this solution?
Thank you

How to insert new records into master and detail forms.
Hello
I cannot have values are inserted in the main view and details at the same time. Scenarios is I a Dept Table (view object-VO1) and employee Table (View Object-VO2) both related to a foreign key, according to HR in Oracle DB XE default schema.
Now, I want to insert the new record into a table Dept (VO1) and the EMP (VO2) by a new say on page (page 2). There is a button on page 1 with button INSERT. I can only drag "CreateInsert" operation on this button for VO1 and VO2. So only text box for records Dept are allow to insert data, but not the Emp records. Is there a way I can insert data into the tables at the sametime?
Thank you
MBHi MuradRabbani,
You can call programmatically two createInsert operations,
Add to your pageDef two CreateInsert operations.
Create a button tha will be master (VO1) insert method call and then call insert for details (VO2) methodHere is an example of code to call the operations:
DCBindingContainer dcb = ADFUtils.getDCBindingContainer (); you need the ADFUtils.java and JSFUtils.java classes. You can find them in the sample applications in your JDeveloper.
OperationBinding oper = dcb.getOperationBinding("CreateInsertVO1");
Oper.Execute ();
-NOTE: at this point, you must set the values that compine the ViewLink on the master in the order detail will know where to link the new record there are many ways to do it.
As solution try to overrdi the method to create on the in the your master vo (VO1) ViewRowImpl
for example
@Override
protected void create (AttributeList attributeList) {}
front
attributeList.setAttribute ("NameOfAttribute", valueHere);
Super.Create (AttributeList);
}------------------
After that, you must call the operation for your VO2 detail
for example
DCBindingContainer dcb = ADFUtils.getDCBindingContainer ();
OperationBinding oper = dcb.getOperationBinding("CreateInsertVO2");
Oper.Execute ();
The detail record will now automatically have the values of your master.
Kind regards

Integrity constraint not found parent key, insert master and detail records
Hello world
I'm creating a master and a detail to record simultaneously, using a managed bean method. I am populating the sequences of db using EL, not database triggers. So:
(1) Insert main record, the new return ID.
(2) Insert detail associated with the previous record
It works well, unless they select a foreign key between the main table and details, so I me "ORA-02291: integrity (XXXX_FK) violated constraint - key not found kinship", as it seems that the book of the child is inserted before the parent.
I would not disable the FK, but can give you advice on this topic?
Thanks in advance,
Jose.Try without defining the status of the Row.STATUS_INITIALIZED...

Hello
If you plan to build your app for Windows, you can use .NET classes. (System.PerformanceCounter), there is a simple example with LabVIEW:

Also, you have several screws that you can use to verify information about the processor.

How can I communicate between MUSE and animate CC OEM element?
Hi all
Please let me know how can I call the Muse javascript function (written using the object > option Insert HTML code) by a click of a button.
This button has been designed and coded using CC animate and its OEM file has been imported in MUSE.
Basically, I'm looking for a solution communicate between MUSE and OEM, and vice versa.
Help, please!
Thank you
AshishK
There is no adequate way to do file OAM control over site of muse. In fact, even a simple button OAM is a html document independent, which has a head, body and its own scripts and html code. OAM - is a site within your site are located in an iframe. This format is used for banners and animations for beauty, but not for the features. If you need the functionality, you must export your animation in html and javascript, disassemble the part code and integrate the muse - something on your mind, in the body. And of course, you have to understand with in the code. But even for a experienced, coders this approach would be absurd. It is easier to make a simple button in cssto integrate this a whopper for the site, which would create a disproportionate burden

How to synchronize data between essbase and planning?
I have an essbase database and a classic of planning an application. They're all two-dimensional entity, year, period and account. I want to synchronize these dimensions. For example, new essbase created members are automatically copied into the planning. Should what tool I use? Dimensions can be shared between essbase and planning?To be honest it looks like you after some of the features within the EPMA, although if you have an essbase database then you will certainly be a source for dimensions for this can be used to fill the demand for planning as well.

dev 6i, db 10 g and win 8.
Hello
I have a master block (stock) and a detail a (product_detail),.
both of them has a column 'product_id ',.
When I try to create a new record or when I enter the query, the number of 'product_id' in the retail block is always displayed.
I don't know why?
Thank you
Hello
If there is a relationship between the two blocs as a relationship of the master / detail by product id so yes it is normal.
all you have to do is to hide this code in the block of retail; make visible property > No.

Master and detail page updated once
Apex 4.1
Oracle 11g
Hi all
I know a lot of people have posted this thread, but I wonder why the detail can be updated when master primary key have no key.
I created the example in OTN
workspace: susanhuang
username: TURTOR
password: TURTOR
request: [email protected] 76130
page 7
main table: dept detail table: emp
I created the process as follows:
because me in 1... apex_application.g_f03. Count
loop
apex_application.g_f03 (i): =: P7_DEPTNO;
end loop;
Updated the APPLYMRU as below
: request as ('SAVE') or: query like '% GET_NEXT' or: query like '% GET_PREV' or: as ('CREATE')
but it did not work, and I know why, because when P7_DEPTNO have no value when run applymru process, then the long-form cannot be saved.
someone help me that how to get the primary key value
Thanks and greetings
God, I finally know where I am going wrong.
For the table in table form, the apex_item was incorporated, so must set once again, so I changed the source of long-form census as usual, which means remove the content apex_item(1,"DEPTNO").
Then changed the process to save the value of primary as key below:
because me in 1... apex_application.g_f03. Count
loop
apex_application.g_f02 (i): =: P7_DEPTNO;
end loop;
Important:
What g_f03.count means the 3rd column must be set to determine how many lines are there in detailed form.
What g_f02 (i) means the column 2, is where is the primary master key.
and it works.
