Hi, Assume I have a bank app.. When customer withdraws $10 from his accouint I have to do following --> update account_summary table [subtract $10 from his account] --> update account detail_table [with other transaction details]
Requirement: either both transactions should succeed or both transactions should be rolled back in case of failure. Question: if my first update succeeds and second fails (say due to space errors .. I have inconsistancy .. Per the thread below stored procedures/functions cannot have commits. I assume that means that they will be implicitly commited ?? How do I approach this simple requirment using psql ?

Nested transactions are on the todo list, but I don't know when they will appear. -- Richard Huxton Archonet Ltd ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
