Hi Everyone,
I am newbie and writing a plpgsql function. I have included source
code here for function. When I execute this function where it finds a
row in table it works fine and gives expected output.
The problem is when I run this function by passing a parameter values
where row does not exist in table. I expect it to print message and
return false. Instead it disconnects from server and throughs lot of
errors in log file. Here is output from executing this function
====When row is found======
called from psql
test=# select func1('2');
NOTICE: Value of ID 2
NOTICE: Value of NDI1
NOTICE: Value of CSSG 5007
NOTICE: Value of Interval Dischargefunc1
-------t
(1 row)
======when row is not found=====
test=# select func1('99');
pqReadData() -- backend closed the channel unexpectedly. This probably means the backend terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
!#
=====also i see following errors in server logfile===
Server process (pid 21536) exited with status 139 at Fri Nov 30
22:28:57 2001
Terminating any active server processes...
Server processes were terminated at Fri Nov 30 22:28:57 2001

Any idea what is happeing?
Appreciate any help?
BTW- where can I find good documentation on plpgsql functions?
TIA

=======Function code========
DROP FUNCTION func1(text);
create function func1(text) returns bool as '

foundfor key %'', key; return false; end if; raise notice ''Value of ID %'', ndiraw_rec.ID ; raise notice
