RE: How can I set a timeout for a locked table in Function ? - Mailing list pgsql-general
Hi,
You cannot set the statement_timeout within a function.
You have to set it before you call the function.
For example, you can try :
BEGIN;
SET LOCAL statement_timeout = 6000;
SELECT * from public.”testlock”();
COMMIT;
The reason why is explained in this post : https://dba.stackexchange.com/questions/82977/why-set-local-statement-timeout-does-not-work-as-expected-with-postgresql-func

state integer,
owner character varying

LANGUAGE 'plpgsql'
AS $BODY$
BEGIN
SET "statement_timeout" = 6000; --- It's not changing. !!
LOCK TABLE public."lock" IN ROW EXCLUSIVE MODE;
UPDATE public."lock" as l set name = 'deneme' WHERE l."id" = 4;
RETURN QUERY
select l."id",l."name",l."state",l."owner" from public."lock" as l, pg_sleep(10) where l."id" = 4;
END;
$BODY$; select * from public."testlock"(); How can I do ?Attachment
