Hi

I am just making a audit table as well.

i have learnt the basics from here http://www.orafaq.com/forum/mv/msg/139165/381806/0/#msg_381806

My problem is that after inserting into audit table if i issue commit command then the table + unsaved data present on the form is also saved.

What i want is that i issue a command which save only inserted record in audit table, and should NOT save data present on the data entry form. (which will be saved later by other method/button).

Please guide.

Thanks

Respected cookiemonster.

I will search how to use pragma autonomous_transaction in forms triggers.

Meanwhile i have seen FORMS_DDL('COMMIT') is accomplishing my objective.

I made a procedure in forms 6 with the following code:

PROCEDURE Delete_audit IS
 pragma autonomous_transaction ;
begin
	
	 
insert into myaudit_invs (source, invdate) values ('Deleting Record', :inv0s.invdate);
delete_record;
  
END;

But it is giving me compilation error that "pragma autonomous_transaction is not a supported pragma".

Kindly guide me what i am missing.

I am using Oracle 10.2.0.1.0

I suppose that Cookiemonster meant that you should do auditing on a database level (i.e. using a stored procedure or a database trigger), not in a form.

Respected Littlefoot

it is sad that i am failed to give true understanding to Cookiemonster.
I respect his response and would like to deviate from his suggestion at the same time.

So, i want to use FORMS_DDL('COMMIT'). Do you think it will create any problem? (for me, it seems to be ok)

FORMS_DDL('COMMIT') issues a commit to the db without kicking off standard forms save processing, so it won't apply changes in datablocks to the db. However, if the form has already made uncommitted changes to the DB (via the post command for example, or a dml statement in a trigger) then this will commit them.

pragma autonomous_transaction will only commit the changes made by the procedure using the pragma and nothing else.

My answer remains - use pragma autonomous_transaction. It's designed for this purpose.

This is what i need exactly. I dont need standard forms saving process while using FORMS_DDL('COMMIT'). I am not using POST command and no other DML statement in pipeline. Hence a perfect solution for me.

I want to learn, how to use pragma autonomous_transaction. The form is not compiling the procedure. This mean that i have to make DB level procedure. Kindly guide me that then i have to pass "forms current value" to DB procedure to accomplish my objective ? am i tight in my thinking?

Here is an example I created some time ago, which shows how to use pragma autonomous_transaction. Have a look.

You'd pass :inv0s.invdate as a parameter to a procedure.
