Default values for Insert and Update
What is the default way the current sysdate to a date on one column table when you perform an insert or update via a form? And related to this, what is the best way by default of the current user (APP_USER) for a varchar2 column when you perform an insert or update via a form?For these columns, I want to display in a report, but they must be hidden on the form, because I have the default app to sysdate and APP_USER values. However, when I tried to use the default values in table in 'the default UI settings' and using either: APP_USER or & APP_USER or SYSDATE, it shows that this literal value on the form (element is not hidden while to debug it). It does not show the actual value, I would, like "user1". Does make sense?
Thanks for your help.

I think that the triggers are the best device.

slow performance pl/sql for insert and update (pls suggestion) required

the query above works only for 1 customer id 6316. It runs in 1 sec.
But if I run for the customer id 10 lakh of input parameter,
(Whenever he runs for unique subscriber id) 10 times lachize it is running.
update by inserting the customer_table table. it becomes slow. What is the real reason behind all this?
Pls help gurus
SOf course, it's slow.
This is the perfect example of HOW not in PL/SQL code.
Cursor fetch in PL/SQL loops are wrong 99% of the time. When you want to process the data in the database? Use SQL statements. Use SQL statements. And use SQL statements.
No PL/SQL.
Use INSERT... SELECT, MERGE, UPDATE (SELECT) and other SQL constructions.
When you want to change it manually (where you manage the treatment), run this SQL via DBMS_PARALLEL_EXECUTE.

default values for sharpness and noise in the develop Module
Capture sharpening
I get my head round sharpening and agree there are three distinct phases: Capture, creative and output sharpening sharpening sharpening
Regarding the Capture sharpening, I noticed that when I import a CR2 file in Lightroom 3.6 there is a pre-set Adobe in the develop Module. Is this a form of Capture sharpening default?
Sharpening

I got the hang of this now. The parameters are the same in ACR and LR - as I might expect that I always use the same camera - but they never vary independently of any setting ISO I can used well

INSERT and UPDATE audit generating more lines expected in $ AUD
Environment:
Oracle 11.2.0.3 EE on Solaris
I had a request for verification of the INSERT and UPDATE on the activities of all the tables in a particular schema. It was in anticipation of a request that will live and the owner wanted to see a 'typical' of some test users activity.
Here are the steps I took:
I also "audit_sys_operations = TRUE' so I know I'll take some SYS audit data in $ AUD as well, but I can ask around those."alter system set audit_trail=DB_EXTENDED scope=spfile; Bounce the instance audit INSERT table, UPDATE table by USERX;
My question is that I see several connections from the application server with "LOGIN" and "LOGOUT" actions and I don't know why they are appearing in the table of AUD $.
Is it because I have auditing enabled for inserts and updates on all THE tables for USERX and opening operations and logoff do I/O in tables that are not owned by USERX under logon logoff procedure?
I'm a newbie audit and the docs I read not answered this question.
I just found an article on the value of 'SESSION_REC' of ACTION_NAME and I need to change my check to "by access. I'll change that and see what happens, but it shouldn't change my question.
Thanks much for any help!

I have the SYS activities audited but I never said anything about the session auditing for this particular user.
"audit session;" check all successful and failed connections to and disconnections of the database, regardless of the user, by session
Is there a way to confirm what has been turned on for auditing?
You can check with the following query
Select * from dba_stmt_audit_opts;

Create triggers in the table, sequence, insert and update with "model"?
It must be of rtfm, trial and error thing but you wanted to ask, is it possible to have models or similar automation for the following scenario:
1.), I add the table to the logic model
2.) Using glossary I transform a relational model that was recovered / synchronized with the data dictionary
3.) then I have the new table to add
-but
I would then have auto-DDL of to be synchronized to database:
-create sequence for the id column
-create table
-create indexes for the id column pk
-Create triggers for insert and update
-l' idea is to have db_created_dt and db_modified_dt defined in the table, so that each table has them to the fields of record etc.
-activate the triggers
Each of them following the same naming convention.
Similarity with approx. generator Apex workshop utils sql create table of the copy paste "excel" that creates 'id' - column + sequence and insert the trigger.
rgrds Paavo
Hi Paavo,
most of the steps can be made in one or other way
-create sequence for the id column
-create table
-create indexes for the id column pk
If you want to start in the logic model and you don't want to have the ID column in the logic model and select 'Create the surrogate key' checkbox in the dialog entity - you will get an identity column in the relational model and the version of database and settings in ' preferences > Data Modeler > model > physics > Oracle "you can set the sequence generation and the trigger for taking in load.
fields of record defined in the table, so that each table has them
You can add the same set of columns in all tables with the transformation script 'model of Table... ».
You can also look here Oracle SQL Developer Data Modeler 4.1 user - defined DDL generation using transformation scripts
to see how to grant your DDL generation using the transformation script. DM comes with example to generate separate tables of logging and triggers. You can create your build script of triggers that support logging in these common columns.

Combining insert and update to a form?
Hello
I am a developer web amateur who is new to dynamic Web sites, php and dreamweaver. I am currently working on a project that uses many forms to send data to a database.
Data that are inserted must also be available to update if necessary. so I need currently 2 versions of each form 1 to insert and the other for the update.
Is it possible to use a single form for insert and update, instead of using 2 forms 1 for each function. This would help reduce the level of duplication on the site.
If so is anyway to do this in Dreamweaver? or could someone point me to an example of how this can be achieved.
Thank you all
Thanks for the information, disappointing that Dreamweaver cannot handle it, but at least I know where I am...
Looks like that's what I need... http://forums.Adobe.com/message/1927405

Want to change the WordPad default values for font size and line spacing
I use WordPad quite heavily because it is simple and fast. But the new version of W - 7 seems to not allow you to change the default values for the font, size and line spacing. The default values are not suitable for a large part of what I do and I'd like to find a way of quickly and easily, either make the changes permanent or change this to open with a single click of mouse or at most two. Any suggestions?
It is the "best" solution to workaround. After you change your Default.rtf custom, simply move it to your system32 directory and add the "Default.rtf" at the end of the location of your target on the property sheet for your file WordPad.exe.
Every time that you open its default location in the directory c:\program files\windows NT\Accessoires WordPad.exe, it defaults to now your Default.rtf custom.

Is there a default value for the color management in PSE10? Beautiful photos from iPhoto, but blur with elements. I need help with this before as I consider that the upgrade to PSE13 and beyond.
Printing which forms an angle seems ok, but one that is horizontally seems faded, incomplete.
I was wondering if I saved a layer somewhere and set it as a default value.
If you group the layers, you will be left with a single layer, thus spreading your concern.
Suggest that you do the following:
- Make sure you have the latest drivers for your printers
- Reset the default preferences.
Hold the Alt, Ctrl + Shift keys when you click the icon to open the items. When asked if you want to delete the settings file, say Yes.
Items nearby and let regenerate the file.

Best way to set the default values for the form elements
Hello
I have a form with a lot of defaults that is mentioned below...
I am currently using calculation-> after presents... then when we create/update a record... these computaion takes place and the default value for the inserted values get... THIS WORKS PERFECTLY WELL.Field value created by :APPL_USER creation_date SYSDATE last_updated_by :APPL_USER last_update_date SYSDATE item1 value1 item2 value2
I want to know... If this approach is fine OR we can have a better approach to achieve...?
Thank you
DeepakHello
I think it's good if it fits your need.
But why you have these fields in the form?
created by: APPL_USER
CREATION_DATE SYSDATE
last_updated_by: APPL_USER
last_update_date SYSDATEThe user can enter the ones?
I thought that those who are to audit and I would fill those drop with trigger in the database.
So that you get the same "correct" values if you need to manipulate the data with example of sql clientBR, Jari

Mr President
Jdev worm is 12.2.1
How to modify and update a line later was inserted and updated in the doDML() method?
I added two rows in my table a method of action-listener in bean managed and secondly with operation doDML() as below.
Method 1-first row in managed bean
public void addNewPurchaseVoucher(ActionEvent actionEvent) { // Add event code here... BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry(); DCIteratorBinding dciter = (DCIteratorBinding) bindings.get("VoucherView1Iterator"); RowSetIterator rsi = dciter.getRowSetIterator(); Row lastRow = rsi.last(); int lastRowIndex = rsi.getRangeIndexOf(lastRow); Row newRow = rsi.createRow(); newRow.setNewRowState(Row.STATUS_NEW); rsi.insertRowAtRangeIndex(lastRowIndex +1, newRow); rsi.setCurrentRow(newRow); BindingContainer bindings1 = BindingContext.getCurrent().getCurrentBindingsEntry(); DCIteratorBinding dciter1 = (DCIteratorBinding) bindings1.get("VdetView1Iterator"); RowSetIterator rsi1 = dciter1.getRowSetIterator(); Row lastRow1 = rsi1.last(); int lastRowIndex1 = rsi1.getRangeIndexOf(lastRow1); Row newRow1 = rsi1.createRow(); newRow1.setNewRowState(Row.STATUS_NEW); rsi1.insertRowAtRangeIndex(lastRowIndex1 +1, newRow1); rsi1.setCurrentRow(newRow1); }
Method of doDML() of line 2 seconds in the entityImpl class
protected void doDML(int operation, TransactionEvent e) { setAmount(getPurqty().multiply(getUnitpurprice())); if (operation == DML_INSERT) { insertSecondRowInDatabase(getVid(),getLineitem(),getDebitst(), (getPurqty().multiply(getUnitpurprice()).multiply(getStaxrate())).divide(100)); } if(operation == DML_UPDATE) { updateSecondRowInDatabase(getVid(),getLineitem(),getDebitst(), (getPurqty().multiply(getUnitpurprice()).multiply(getStaxrate())).divide(100)); } super.doDML(operation, e); } private void insertSecondRowInDatabase(Object value1, Object value2, Object value3, Object value4) { PreparedStatement stat = null; try { String sql = "Insert into vdet (VID,LINEITEM,DEBITST,AMOUNT) values ('" + value1 + "','" + value2 + "','" + value3 + "','" + value4 + "')"; System.out.println("sql= " + sql); stat = getDBTransaction().createPreparedStatement(sql, 1); stat.executeUpdate(); } catch (Exception e) { e.printStackTrace(); } finally { try { stat.close(); } catch (Exception e) { e.printStackTrace(); } } } private void updateSecondRowInDatabase(Object value1, Object value2, Object value3, Object value4) { PreparedStatement stat = null; try { String sql = "update vdet set vid='"+ value1+"',lineitem='"+ value2+"',DEBITST='" + value3 + "', AMOUNT='" + value4 + "' where VID='" + VID + "'"; System.out.println("sql= " + sql); stat = getDBTransaction().createPreparedStatement(sql, 1); stat.executeUpdate(); } catch (Exception e) { e.printStackTrace(); } finally { try { stat.close(); } catch (Exception e) { e.printStackTrace(); } } }
Now the problem is that when later I change the quantity and price of the first line isn't updated but second row, because I used the command
<af:button actionListener="#{bindings.Commit.execute}" text="Commit"
This button update the first line added by bean managed, but the second row remains unchanged.
Please help how to update the two lines with the same button or something else.
Concerning
DML_UPDATE will call only if there is some change data attributes.
I guess that the update statement is false because vid looks like a primary key for the table, then, how update you the primary key of the update statement and how the update condition statement where the vid = '0'
I assume the update statement should look like:
private void updateSecondRowInDatabase(Object value1, Object value2, Object value3, Object value4) { PreparedStatement stat = null; try { String sql = "update vdet set lineitem='" + value2 + "',DEBITST='" + value3 + "', AMOUNT='" + value4 + "' where VID='" + value1 + "'"; System.out.println("sql= " + sql); stat = getDBTransaction().createPreparedStatement(sql, 1); stat.executeUpdate(); } catch (Exception e) { e.printStackTrace(); } finally { try { stat.close(); } catch (Exception e) { e.printStackTrace(); } } }

CORE Production 11.2.0.4.0
AMT for Linux: Version 11.2.0.4.0 - Production
NLSRTL Version 11.2.0.4.0 - Production
I create the structure of the table like that.
create table test1 (a primary key, b (2) char number, date c, d varchar2 (10), date of e);
create table test2 (number of ab, cd (2) tank, date of the ef, gh varchar2 (10), date of the ij, kl varchar2 (100));
Create materialized view log on test1;
create materialized view fast refresh test1_v on commit in select * from test1;
I have create a trigger of the sample
CREATE OR REPLACE TRIGGER test1_trig
AFTER INSERT OR UPDATE OR DELETE
ON test1_v
FOR EACH LINE
DECLARE
lr_test2 test2% ROWTYPE;
lv_error VARCHAR2 (4000);
BEGIN
lr_test2. AB: =: NEW.a;
lr_test2. CD: =: NEW.b;
lr_test2. GH: =: NEW.d;
IF THE INSERTION
THEN
lr_test2. EF: = SYSDATE;
lr_test2.IJ: = SYSDATE;
lr_test2.KL: = 'INSERT ';
INSERT INTO test2
VALUES lr_test2;
ELSIF UPDATE
THEN
lr_test2.IJ: = SYSDATE;
lr_test2.KL: = 'UPDATE ';
UPDATE test2 = lr_test2 ab WHERE = LINE: OLD.a;
ELSIF REMOVAL
THEN
DELETE FROM test2
AB = WHERE: old.a;
END IF;
EXCEPTION
WHILE OTHERS
THEN
lv_error: = SQLERRM;
INSERT INTO XXDOMINO_FG_DATA_LOAD_ERROR
VALUES ('test1_trig',
: OLD.a,.
"test1_trig,"
LV_ERROR,
SYSDATE);
COMMIT;
END test1_trig;
/
So, if check you my code,.
When I insert EF = SYSDATE, IJ = SYSDATE.
Update EF is not changed, IJ = SYSDATE.
So I like to capture their insertion and update dates.
But if updates or insert arrives on the materialized table. The trigger themselves as an INSERT only.
So how do you capture the updates?
I use the statemnet with out merger with performance and also able to capture the update dates.
CREATE OR REPLACE TRIGGER test1_trig_merge
AFTER INSERT OR UPDATE OR DELETE
ON test1_v
FOR EACH LINE
DECLARE
lr_test2 test2% ROWTYPE;
lv_error VARCHAR2 (4000);
BEGIN
IF THE REMOVAL
THEN
DELETE FROM test2
AB = WHERE: old.a;
ELSIF INSERTION
THEN
MERGE INTO test2 one
B using (SELECT 1 FROM DUAL)
WE (ab =: new.a)
WHEN MATCHED
THEN
UPDATE the VALUE ab =: NEW.a.
CD =: NEW.b,
GH =: NEW.c
IJ = SYSDATE,
KL = "Update"
AB WHERE =: old.a
WHEN NOT MATCHED
THEN
INSERTING VALUES (: NEW.a,)
: NEW.b,.
: NEW.c.
: NEW.d,.
: NEW.e,.
"INSERT");
END IF;
EXCEPTION

THEN
