Dear all,
i would set a script timeout from a .net application. My problem regards how to make sure that time out will be reset at the end of the script such as
SET statement_timeout 1000
SELECT pg_sleep(2);
trowhs exception
After that
SELECT pg_sleep(2);
wouldn't throw exception.
Can you help me to solve this issue?
Many thanks in advance.
BR
Roberto

This should work.
SELECT set_config('statement_timeout','1000 s',false);
The set_config function is quite flexible as can accept dynamic values.
More info here
http://www.postgresql.org/docs/current/static/functions-admin.html
I've used successfully to change the script timeout for each statement in
my maintenance scripts using a temporary table to store the deadline.
Kind Regards
Federico

Hi,
I think your suggestion is
SELECT set_config('statement_timeout','1000 s',false); -- enable timeout
--
-- DO SQL Statements here
--
SELECT set_config('statement_timeout','0',false); -- disable timeout
Am I correct? Moreover what can happen if another query runs on the same connection pool ?
I would limit the effect only on this specific query.
Roberto

Hi ,
When you don't specify unit, it's in ms.
See the test bellow:
BR
Patrick KUI-LI
postgres=# SET statement_timeout TO 1000;
SET
Time: 0.214 ms
postgres=# show statement_timeout;
statement_timeout
-------------------
1s
(1 row)
Example with unit:
postgres=# SET statement_timeout TO '1000s';
SET
Time: 0.229 ms
postgres=# SELECT pg_sleep(2);
pg_sleep
----------
(1 row)
Time: 2001.566 ms
postgres=#
