how to check SQLSTATE

am Thu, dem 05.10.2006, um 17:45:36 -0300 mailte Hugo folgendes:

Hi,

is it possible to check for sqlstate inside a function , something like:
....
loop
fetch bla.....
if sqlstate = '02000' then
exit;
end if;
....
end loop;
if I try to save the above I get a : sqlstate not defined error

Which version?

With release 8.1 you can use SQLSTATE and SQLERRM inside exception
blocks.
-> http://www.postgresql.org/docs/8.1/interactive/release-8-1.html

You can find the errorcodes there:

my fuction:

the symbol is correct , i checked it in the appendix A postgres error codes
and constants, have you got any idea what the problem could be.
....
loop
Begin
fetch bla.....
Exception
when no_data then
exit;

end loop;

NO_DATA isn't an error condition, only a warning, thus there is no case
in which an exception block would trap it. So plpgsql doesn't bother to
recognize it.

Hi,

update sentence in a trigger function ??
