I'm trying to create a function that loops through records returned from a
query. This is what I came up with but it doesn't work. Can anyone tell me
what I'm doing wrong?
CREATE FUNCTION test_loop(INT4, VARCHAR)
RETURNS INT4
AS 'DECLARE
int_key ALIAS FOR $1;
var_test VARCHAR;
BEGIN
var_test := $2;
FOR row IN SELECT * FROM companies LOOP
UPDATE companies SET name = var_test;
END LOOP;
RETURN int_key;
END;'
LANGUAGE 'plpgsql';
Here's how I call the test loop and the error I get:
db=# SELECT test_loop(1, 'testing');
ERROR: parse error at or near ";"
db=#
Thanks
