Hi,
if I do a SELECT on a non-existing table, SPI_exec won't return.
I get, e. g. in pgaccess, an error message "<table> does not exist",
and my code below the function call is never reached.
So why return error codes for SPI_exec when you cannot evaluate them?
The background:
I need to distinguish different client connections within a trigger
function.
To do this, I create a temporary table within a "login" function.
My trigger must check for the existence of this function.
I cannot think of any other method, since there is no "connection id" or
something like that!
This would also be an application for checking the existance of a
temporary table,
as was asked for in another thread in this list before.
How can I check for the existence of a temporary table without getting
interuppted?????
Thanks,
Markus
