Hi All

Does anyone know if Postgres supports Catching of errors, from an EXECUTE,
for Procedural Language Postgres.

Thanks in advance

Kind Regards,
Shaun Clements

In version 8, yes. See the manuals (35.7.5. Trapping Errors) for details.

Try a
Begin
... block to watch ...
Exception
When error_code then
... What to do ...
End;

block, it works to me, it is better explained in the manual..

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)

I unfortunately have to use 7.3.
Will try the Exception wrap. It does appear in the manual.

No it doesn't. Version 7.3 doesn't have any programmatic exception
handling. Perhaps you are reading the wrong version of the manuals?

Re: Catch of ERROR in PLPGSQL

Begin
Exception
of a basic Function.
is provided for.
What I was thinking then, it to create separate functions for the INSERT and
UPDATE
which take parameters, for the table, column, and values.
Which I can then make use of the EXCEPTION.

Kind Regards,
Shaun Clements
