Loop Through Records in Oracle Form's Tabular Data Block

In the following example, it will execute the query in the EMP block and will loop through all the records, to calculate the total salary.

DECLARE
   l_sal   NUMBER;
BEGIN
   GO_BLOCK ('emp');
   EXECUTE_QUERY;
   -- move pointer to first record
   FIRST_RECORD;
   l_sal := 0;

   LOOP
      l_sal := l_sal + :emp.sal;

      IF :SYSTEM.LAST_RECORD = 'TRUE'
      THEN
         EXIT;
      END IF;

      NEXT_RECORD;
   END LOOP;
