Updated column in trigger

Hi,
How can i know if a particular column is updated in trigger ?
Thanks

Hi,
I don't have the manual page handy, but search in the CREATE TRIGGER statemenet manual page, and you'll find out pretty quick.
Little hint:CREATE OR REPLACE TRIGGER mtrig
BEFORE UPDATE ON mtab
FOR EACH ROW
BEGIN
IF (:OLD.col != :NEW.col) THEN
NULL; -- value of mtab.col is being updated!
END IF;
END;
/Regards,

Get OLD&NEW value of an UPDATED column selected dynamically in a Trigger

Hi All,
I am writting a trigger which take column name dynamically. And on the basis of that column it should give me old value as well as updated value of a column corresponding to a modified row.
OOO_SCHEDULE is my table name;
Note: This is only for test so I am writting only for update not for insert and delete.
create or replace trigger "OOO_SCHEDULE_AUDIT"
BEFORE
insert or update or delete on "OOO_SCHEDULE"
for each row
begin
DECLARE
v_username varchar2(30);
AUDIT_EMP_ID varchar2(30);
AUDIT_EMP_ID_NEW varchar2(30);
v_Column_name VARCHAR(30);
v_stmt1 VARCHAR(40);
v_stmt2 VARCHAR(40);
CURSOR C1 is
select COLUMN_NAME from user_tab_columns where table_name='OOO_SCHEDULE';
BEGIN
OPEN c1;
LOOP
FETCH c1 into v_Column_name;
EXIT WHEN c1%NOTFOUND;
v_stmt1:=('OLD.'||v_Column_name);
v_stmt2:=('NEW.'||v_Column_name);
AUDIT_EMP_ID:=v_stmt1;
AUDIT_EMP_ID_NEW:=v_stmt2;
INSERT INTO TEMPTEST VALUES(v_stmt1);
INSERT INTO TEMPTEST VALUES(AUDIT_EMP_ID);
END LOOP;
CLOSE c1;
END;
end;
Suppose OOO_EMP_NAME is the column name where user made the change.
If i do like this..
AUDIT_EMP_ID:=OLD.OOO_EMP_NAME;
AUDIT_EMP_ID_NEW:=NEW.OOO_EMP_NAME;
Then it is working fine because I have given column name statically. But I want the column name to be selected dynamically and I am able to do it through cursor. Also I am able to fetch all column names in v_Column_name variable one by one dyanamically for the cursor.
But by executing these statements
AUDIT_EMP_ID:=v_stmt1;
AUDIT_EMP_ID_NEW:=v_stmt2;
I am getting OLD.OOO_EMP_NAME and NEW.OOO_EMP_NAME rather then old and new values of the updated column.
Please help me identifying the problem, where I am doing the mistake? What is the correct way to execute these statements? So that I can get old and new values of the column (updated column).
I have tried it by passing in a procedure also but don't know how to execute this dynamic statement to get the old and new values.
Thanks,
Ishrat.

In the given link, column name has been selected statically. But i want that column name should be selected daynamically throgh loop and then check the
condition for any update corresponding to that column value. I don't want to write as many if condition as the no. of column name. I just want one if condition for all column namesDon't be lazy. Write all column names into your trigger. Or use a way to create the trigger "dynamically".
What is the problem that you have with static column names? "I don't want to write many..." is not a problem, but an opinion.

How to obtain the updated column name in a trigger?

Hello everyone,
I need to know for audit propose the updated column name in a After Update Trigger on a Table.
The table have more than 20 columns, and i think that do more than 20 conditions asking for the difference between the :new value and the :old value is not the best way.
Thanks for the help!

Hi,
Thanks to all for the replays.
I didn't know that i can pass the column name to the UPDATING. This is only possible on 10g??
Any way, i pass the column name and works fine, but i have another issue because of that.
I obtain the column name from a cursor that query user_tab_columns view, when i try to obtain the value of the :old or :new, i can't because i don't know how to obtain the value of the value.
This example show better:
DECLARE
vOldValue Varchar2(50);
Cursor cur_Column_Names Is
Select COLUMN_NAME
From User_Tab_Columns
Where TABLE_NAME = 'table_name';
BEGIN
For var_cursor In cur_Column_Names Loop
If Updating(var_cursor.COLUMN_NAME) Then
vOldValue := '?'; -- How obtain the value of the :old. + >var_cursor.COLUMN_NAME??
End If;
End Loop;
END;Thanks to all for the help.

Inconsistent behaviour of Sybase SQL anywhere update column trigger

Hi, all
I am not sure where to post this issue, since I could not find a forum for Sybase SQL anywhere.
The problem is as follows:
The definition of the update column trigger in help is this:
UPDATE OF column-list
Invokes the trigger whenever a row of the associated table is updated such
that a column in the column-list is
modified.
However, there are cases when the triggers are launched even when the columns are not modified (ie the same exact value is in the both OLD and NEW row)
This happens on BEFORE triggers, never saw it happening on AFTER.
Ways to replicate the problem:
1. Define a before trigger, which fires on update of a specific column in any table.
2. Run an sql which says "update table1 set column1 = column1 where ... "
3. You will see that trigger fires, even though it is not supposed to.
Is this an expected behaviour on "BEFORE" triggers?
Arcady

If this were a sql server question, then I could tell you that this is by design. A trigger will be executed regardless of the number of rows affected (including zero) and regardless of whether any column in any of the affected rows was changed. I will also point out that PB was designed to work within this design by the inclusion of the [where clause for update/delete] option in the update properties of the datawindow. The idea is that you avoid actual row updates (in the table) where nothing has actually changed (and it also supports collision avoidance).
Based on the history, I would assume that Sybase works exactly the same.

Update column data to Upper Case in parent and child table

Hi ,
I am facing issue while updating column value to upper case in parent table and child table. How can i do that ?
when updating parent row:
ORA-02292: integrity constraint (XXXXXXXXXXXXXX_FK) violated - child record found
When updatng corresponding child row:
ORA-02291: integrity constraint (XXXXXXXXXXXXXXXX_FK) violated - parent key not found
how can i update on both the places ?
Regards,
AA

I am facing issue while updating column value to upper case in parent table and child table. How can i do that ?
Why do you need to do that?
That is just ONE of several questions you should answer before you start modifying your data.
1. What is your 4 digit Oracle version? (result of SELECT * FROM V$VERSION)
2. If both values are the same case what difference does it make what that case is?hen you don't need to alter your original data.
3. What is the source of the column values you are using now? If you change your data to upper case it will no longer be identical to the source data.
4. What is your plan for enforcing future values to be stored in UPPER case? Are you going to use a trigger? Have you written and tested such a trigger to see if it will even work the way you expect?
5. Why aren't you using a surrogate key instead of a 'business' data item? You have just demonstrated one reason why surrogate keys can be useful: their actual value is NOT important.
You should reexamine your problem and architecture and consider other alternatives.
One alternative is to add a new 'surrogate key' column to use as the primary key. Just create a new sequence and use a trigger to populate the new column. Your current plans will require a trigger to perform the case conversion so instead of the just use the trigger to provide the value.
If the change is being done to facilitate searching you could just add a VIRTUAL column UPPER_MY_COLUMN and index that instead. Then you could search on that new virtual column and the data values would still be identical to the original data source.

Column level trigger

Hi All -
I have a table which has 6 columns
create table main_tbl
(p_id integer,
p_lname varchar2(20),
p_fname varchar2(20),
p_dept varchar2(15),
p_office varchar2(15),
p_ind char(1)
And I have a corresponding audit/history table
create table main_tbl_audit
(p_id integer,
p_lname varchar2(20),
p_fname varchar2(20),
p_dept varchar2(15),
p_office varchar2(15),
p_ind char(1)
As part of the application audit process, I want to move a record from main_tbl to main_tbl_audit only when a column value changes. I can do this using a column level trigger but if I use column level trigger and if for example 3 values are changed in the main_tbl at once then it will create 3 different rows in the main_tbl_audit table.
Is there a way to always create one row in main_tbl_audit table even if a record in the main_tbl table has one or more column value changes.
Please share your expertise.
Thanks,
Seenu001

I'm not quite sure what you mean by a "column-level trigger" since there is no such thing in Oracle. You can specify a list of columns in the OF clause of a row-level trigger, so I'm guessing that's what you're talking about. But then I don't understand why you would get three rows in the audit table. Unless you created three different row-level triggers each of which specified a single column?
Why wouldn't you simply have a single row-level trigger that compared the old and new values, i.e. (ignoring NULLs)
CREATE OR REPLACE TRIGGER trg_audit_main
BEFORE UPDATE ON main_tbl
FOR EACH ROW
BEGIN
IF( :new.p_lname != :old.p_lname or
:new.p_fname != :old.p_fname or
THEN
INSERT INTO main_tbl_audit ...
END IF;
END;Justin

Mass Update Column In Tabular Form

Hi,
I'm trying to create a tabular form that has a mass update column function. i.e. the tabular form will be displayed as normal but at the top of certain columns will be a text box or lov and what ever is entered into those boxes will be cascaded into the empty values in that column without refreshing the page.
Hope that makes sense.
I've search the forum but cant find reference, is this possible.
Thanks Andy

Hi,
Just wondering if anyone had any thoughts on this.
I can get the text to populate another cell e.g.
http://mlw-mis-2/dev/apex/f?p=174:4
But how can i get it to reference a column, this is what I'm using to reference another item
onKeyUp="f_getTextUpper('P4_COL1','P4_TEXT')"
and I've tried changing the P4_TEXT to other things like
apex_application.g_f03 (vRow)
apex_application.g_f03 (i)
apex_application.g_f03
But with no luck

Int Server (ABAP Cache) - Cache Updated column shows "red"

...long read, appreciate your patience...
In the IB:Config, under Cache Notifications, I'm getting the red square in the Cache Updated column for all "ABAP Cache" entries (green for notification). The "Java Cache" and "Central Adapter Engine" entries are green all the way through.
I've read a bunch of other threads here, and I've read and worked through the entire "How to Handle Caches" document. I ran in to a couple issues, but I don't know how to solve them.....
1) When I run SXI_CACHE, I receive the following messages:
<green> "Cache contents are up to date"
<red> "Error during last attempt to refresh cache"
--->double-clicking shows: Error ID = BUSINESS_SYSTEM, Message = LCR_GET_OWN_BUSINESS_SYSTEM - NO_BUSINESS_SYSTEM
--->Running the LCR... fxn via SE37 is successful, so I don't understand why SXI_CACHE has a problem running it.
2) When I run the Cache Connectivity Test where the Yellow triangle is displayed for the IS-ABAP with message "Attempt to fetch cache data from Integration Directory not yet started or still in progress".
3) When I try to load http://<host>:<port>/CPACache/refresh?mode=delta or full, I get a "403 Forbidden - You are not authorized to view the requested resource." But I'm never prompted for a user/pw? Since I'm the only user in this XI box, I do have some of my logons saved in Internet Explorer - could it be using one of those without prompting me?
Note:
I have been experiencing on and off network issues, and the machine we have XI installed on is slow. I don't know if that could affect anything or not.
Thanks for taking the time to read this...
Brian

Thanks for the replies...
Prashanth,
I think SXI_CACHE is for items in the Java stack only (correct me if I'm wrong). The main problem I have is with items in the ABAP stack not making it in to the cache.
Moorthy,
I walked through the Readiness Check - everything passed except for the items I already mentioned (Cache test shows yellow). The document is a nice gathering of tests, but it doesn't offer any ideas has to how to correct problems encountered.
Integration_directory_hmi tested successfully, and I read through the other OSS Notes, but none solved the issue.

Combine checked item and update column

Hi all,
need to design a screen that allow user to update column (code) and also pick which statement to display for the next stage. My thought was to create a checkitem and LOV display. Once user has checked the box , the process should update the code first then select the checked item into a new table. But it appears to me I can get checked item cocept to work and inserted it to a new table but fail to address the LOV update. Can you help ?
table: sample1, display as the following
seq     code     comments amt
1     T     test1     30
2     A     test2     20
3     T     test3     80
4     T     test4     20
user action: picked seq 1,2 and update code from A to T for seq2
==> process will insert the selected statement to result table
table:result
seq     code     comments amt
1     T     test1     30
2     T     test2     20mushar

I am sorry . Just realized I posted this to a wrong forum.

Update Column value after current item is Approved and then publish major version using Sharepoint 2013 designer workflow

Hi,
We have a requirement to update a column value once the item has been approved.
Following settings have been made in the publishing articles list:
Require content approval for submitted items : yes
Create major and minor (draft) versions
Who should see draft items in this document library? :Only users who can edit items
Require documents to be checked out before they can be edited? : yes
I have createdatu a Sharepoint 2013 workflow to check if Approval sts of current item = 0 i.e. Approved , then check out and update the item and finally checkin the item. Everything works fine till this point except that the minor version of the item is
checked in. Due to this the updated columns are not published to others.
Also, I created a Sharepoint 2010 workflow to SET CONTENT APPROVAL = APPROVED and started this workflow from my list workflow above, but the item does not get checked-in and always shows "In Progress" status with comment "The item is currently
locked for editing. Waiting for item to be checked in or for the lock to be released.".
Please let me know where I am missing out so that once the item is approved, column value gets updated and current item is still in Approved status.
Thanks

Hi,
According to your post, my understanding is that you want to update Column value after current item is Approved and then publish major version using Sharepoint 2013 designer workflow.
You will get into this kind of Catch-22 situation trying to set the Content Approval Status in SharePoint Designer workflow:
- You must check out the document before you can change the Content Approval Status
- You can't change the Content Approval Status once the document in checked out
Since you set the Require documents to be checked out before they can be edited=Yes, you will need to check out the document when run the workflow on the item. But you cannot approve a document when it is checked
out. So the logic in workflow conflicts.
As a workaround, you can use the Start Another Workflow action to start the normal Approval workflow on the document. The built-in Approval workflow can work with a document that’s not checked out.
The designer approval workflow also can work with a document that’s not checked out.
You can create two workflow using SharePoint Designer 2013.
First, create a SharePoint 2010 platform workflow.
Then, create a SharePoint 2013 platform workflow.
Then when the SharePoint 2013 platform workflow start, it will start the SharePoint 2010 platform workflow to set content approval status, then the SharePoint 2013 platform workflow will update current item value.

Hz_party_site_v2pub.update_party_site-You cannot update column location_id

Hi All,
I am working on customer conversion and need to call hz_party_site_v2pub.update_party_site. It throws me error "You cannot update column location_id".
Follwoing is the scenario:
1. Initially, I create a customer, with bill to and ship to addresses different from each other.
New Customer: 12345678
Bill To: 1 ADDRESS
Ship To: 2 ADDRESS
Result:
1 customer got created.
2 sites got created one for bill to and one for ship to.
2 Locations got created , one for bill to and one for ship to address.
2. Now, I try to update the bill to and ship to address for the customer and my new bill to ship to are
Bill To : 1 ADDRESS
Ship To: 1 ADDRESS
Now, when the code hits the point hz_party_site_v2pub.update_party_site() it returns the error message "You cannot update column location_id".
Any pointer to resolve the issue or throw some light on the situation would be of great help.
Thanks in Advance !

Update columns

When I was trying to update columns, I met two different problems:
1. Source column with COLUMN1 VARCHAR2(70 BYTE); Target column with COLUMN2 VARCHAR2(50 BYTE)
2. Source column with COLUMN3 NUMBER(38,0); Target column with COLUMN4 NUMBER(10,0).
When I was trying to update COLUMN2 with COLUMN1 and COLUMN4 with COLUMN3, I got following error message:
SQL Error: ORA-01401: inserted value too large for column
01401. 00000 - "inserted value too large for column"Please help me to do the update?
Thanks a lot!!

Hi,
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements for all tables) and the results you want from that data.
If it's a DML problem (including UPDATE) then the sample data should show the tables as the exist before the changes, and the results will be the contents of the changed table(s) after the changes.
As Sybrand pointed out, "inserted value too large for column" is one of those error messages that really means what it says. You can't store a 70-character string in a VARCHAR2 (50 BYTE) column. You can't store a 38-digit number in column limited to 10 digits.
What do you want to do when the source data won't fit in the destination columns?
Do you want to use it, unchanged? Then use ALTER TABLE to allow bigger values in the destination table.
Do you want to use some abbreviated form of the source data? Use fucntions such as SUBSTR, as Saubhik suggested.
Do you want to ignore data that won't fit? Use CASE to map the values that won't fit to NULL.
Do you want something else? Say what you want, and someone will help you do it.

Update column based on values of same table

I have table T1 with 4 columns 'col1','col2','col3','col4', 'col5','col6' as follows
Col1     Col2     Col3     Col4     Col5     Col6
1111     City1     C     AA     DDD     A1
2222     City 1          DD     HHH     A1
3333     City2     B     EE     OOO
4444     City 1     B     JJ     SSS     A1
5555     City2     C     KK     VVV
6666     City2          RR     QQQ
7777     City2     B     XX     BBB
I have already updated Column 6with value ‘A1’ where Column 2 is ‘City1’.
Now I want to update col 6 where col2 is ‘S’ with following conditions
If Col 3 = ‘B’ then Col6 should be = col4
else it should be = col5

SET col6=DECODE(col3,'B',col4,col5)
WHERE col2='S'

Using cursor to update column, is this inefficient or illegal?

I have declared a cursor as follows in a PL/SQL procedure:
     cursor C is SELECT a FROM t
FOR UPDATE;
Later on in the procedure, I've written the following:
update t
set b = 'text'
where current of C;
My question is, am I allowed to do this when the column I am updating is not the one which I have selected in the cursor? If this is indeed legal, are there any performance issues involved?
Thanks,
Peter

Peter,
As it is confirmed by our folks that it is LEGAL to update columns that are not
fetched in the CURSOR, I am just going to talk about other things.
CURSOR is a read only resultset in PL/SQL which just gives you a handle to each of the rows that you are fetching from one or more table(s), based on the columns that you select in CURSOR. It is advised that you select the ID columns of the table(s) like PK if available from those tables so that you would not run into updating rows more than what is actually required. If we are not fetching the rows based on UNIQUE value and we use these values in UPDATE statements inside, we may get into trouble. Alternative and proves very good with performance is ROWID. I have used ROWID in CURSOR fetches and it works great.DECLARE
   CURSOR empCur IS
   SELECT ROWID unique_col, ename, job, sal FROM EMP
   WHERE sal > 1000;
BEGIN
   FOR empRec IN empCUR
   LOOP
      UPDATE emp SET job = 'Tech Lead'
      WHERE ROWID = empRec.unique_col;
   END LOOP;
END;Andrew,
Just curious, could you educate me on MVP status from Brainbech?
Thx,

Working with an updatable column

Hello,
I have an updatable column that is being displayed as a textfield. I correctly set the reference table and column name under the column attributes and the report is generated by an updatable SQL query. I'd like for the user to change the data (it's a simple NUMBER) on the report and then be able to have the change on the database.
I tried to create a Multi-Row update but it didn't seem to be working correctly. Could someone point me to, or shed a light on, a PL/SQL process or Multi-Row update that could correctly update the altered rows in the database.
Thanks!

Ted,
You're probably best of creating this as a tabular form using the tabular form wizard. This generated the tabular form / updateable SQL query for you, along with all the needed primary key column(s), etc and created the MRU process as well. Of course you can also created this manually, just make sure your column names in your query correspond with the actual column names in the table you're trying to update. You have a primary key column, and reference that primary key column and the table properly in your MRU process.
Regards,
Marc
