Hi Bartek,

Thanks for the quick response.

Syntax error cleared up and loads fine but executing the stored
procedure fails to update the row.

Regards,

Patrick

Hi,
instead of
update workorderRecord set wfstatus='failed';

try:
workorderRecord.wfstatus := 'failed';

I haven't tested, but workorderRecord is ROWTYPE, so shouldn't be
updated like a table.
I'm sticked to 9.1, hope the same is for 8.1
http://www.postgresql.org/docs/9.1/static/plpgsql-declarations.html

According to doc for 8.3 it looks the same
(http://www.postgresql.org/docs/8.3/static/plpgsql-declarations.html)
so should work.

Regards,
Bartek

Hi,

I'm trying to update a record within a for loop and at the point
of updating I get the following syntax error:

ERROR: syntax error at or near "$1"
LINE 1: update $1 set wfstatus='failed'
^
QUERY: update $1 set wfstatus='failed'
CONTEXT: SQL statement in PL/PgSQL function
"workorder_status_integrity_check" near line 13

********** Error **********

ERROR: syntax error at or near "$1"
SQL state: 42601
Context: SQL statement in PL/PgSQL function
"workorder_status_integrity_check" near line 13

Below is the procedure in question using Postgres 8.1:

CREATE OR REPLACE FUNCTION workorder_status_integrity_check()
RETURNS integer AS $$
DECLARE
workorderRecord workorder%ROWTYPE;
declare counter int DEFAULT 0;
BEGIN

FOR workorderRecord IN SELECT * from workorder LOOP

IF workorderRecord.wfstatus = 'canceled' THEN
counter = counter +1;
ELSEIF workorderRecord.wfstatus = 'finished' THEN
counter = counter +1;
ELSE
update workorderRecord set wfstatus='failed';

END IF;
END LOOP;
RETURN counter;
END;
$$ LANGUAGE plpgsql;

Thanks, Patrick
