Thread: how to rollback transactions in a function?

how to rollback transactions in a function?

From
"V R"
Date:
Hi,
   I  have written a parent function, which inturn, calls 2-3 child functions  that
eitherinsert or update rows in  tables .The problem I face is when one of these child functions fail to
update or insert and return False.So in this scenario how do I rolback the transactions made by the earlier
childfunctions ? Any feedback regarding this will be helpful. 
 
Thanks
