Обсуждение: Record unassigned yet
Hello, I'm experiencing a strange problem. Here it is : I've created a function with a FOR loop. DECLARE Current RECORD; BEGIN FOR current IN SELECT * FROM employees LOOP Tmp := current.id; END LOOP; ... When I call the function, I get the error :ERROR: record " current " is unassigned yet Any idea?
