Re: Stored Procedure Record Updates using For Loops - Postgres 8.1

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
