Me again, I've reworded it, but its still rolling back !!! Using the code below, if I call : select app_security.validateSession('XYZ','10.10.123.43','Z',5,5); I get an error raised on the select that follows cleanSessionTable. Which is fine. BUT, Postgresql is still rolling back ! If I go back afterwards and say select app_security.validateSession('XYZ','10.10.123.43','Z',5,5); I get the session data shown to me again ?
