Mixing Range and Expression Lists in the Same FOR Statement

If loop_var is an INT or SMALLINT value, you can mix ranges and expression lists in the same FOR statement. The following example shows a mixture that uses an integer variable. Values in the expression list include the value that is returned from a SELECT statement, a sum of an integer variable and a constant, the values that are returned from an SPL function named p_get_int, and integer constants:

CREATE PROCEDURE for_ex ()
   DEFINE i, j INT;
   LET j = 10;
   FOR i IN (1 TO 20, (SELECT c1 FROM tab WHERE id = 1),
         j+20 to j-20, p_get_int(99),98,90 to 80 step -2)
      INSERT INTO tab VALUES (i);
   END FOR;
END PROCEDURE;
