Re: Catch exceptions outside function

Hi

this is my script in details, remember that I launch it by .Net code (devart connector):


SET LOCAL statement_timeout TO 1000;
BEGIN;

SELECT pg_sleep(5); -- QUERY that is long running;

-- Some exception catch such as EXCEPTION

END;


I supposed my code can throw an eception for timeout and I would catch it. Otherwise consecutives queries report "Transaction is aborted message error".

Do you have any suggestion for me?

Thanks again
Roberto

That's a bit unclear.
What do you mean by "outside a function but in a script"?
Can you explain in more detail?

The code sample you paste looks like PL/pgSQL.

You cannot commit or roll back in PL/pgSQL.

If you want to undo in case of error whatever happens in the block,
just replace the ROLLBACK with NOOP.
