Postgresql cursor loop

Postgresql cursor loop

Postgresql cursor loop

(OP)
Hi,
I'm new to postgresql. I'm trying to get a function that will loops through a cursor, and update every row. I have tried various permutations of the below, but am getting syntax errors. Can anyone suggest what is wrong with the given example?


DECLARE
curs1 CURSOR
FOR
SELECT *
FROM myTable ;

BEGIN

FOR i IN curs1  LOOP

UPDATE myTable
SET field3 =
i.field1 ||
i.field2
WHERE CURRENT OF curs1;

END LOOP

This gives me the error:

ERROR:  syntax error at or near "$1" at character 3
QUERY:    $1

Any ideas?
END;
