Transaction-control and locking statements. Transactions cannot be nested. END compound statement. The latter does not cause an implicit commit. See Section In this post, I demonstrate the kind of scenario that will result in an ORA errors. I then show the "traditional" solution, using a collection defined in a package.
Then I demonstrate how to use the compound trigger, added in Oracle Database 11g Release1, to solve the problem much more simply. All the code shown in this example may be found in this LiveSQL script. Read more. October 31, That's the default and only setting for cursor FOR loop optimizations. It offers a sweet spot of improved performance over row-by-row and not-too-much PGA memory consumption. Test to see if that's fast enough likely will be for many cases.
If not, try higher values until you reach the performance level you need - and you are not consuming too much PGA memory. Don't hard-code the limit value: make it a parameter to your subprogram or a constant in a package specification. Don't put anything in the collection you don't need. September 18, You can't really declare your own "user-defined" scalars, though you can define subtypes from those scalars, which can be very helpful from the p. Thanks, Tom.
And just to emphasize, the implicit commits occur only for the DDL commands that change the data dictionary. Am I right, Tom? Just ddl that does stuff to the data dictionary. Why not autonomous transaction? Can you clarify? June 24, - am UTC. Thanks Rangadham. February 26, - am UTC. Rangadham, March 17, - am UTC. March 17, - am UTC. Hi tom, how will i execute procedure with ref cursor as a out parameter.
