ITERATE label

ITERATE can appear only within LOOP, REPEAT, and WHILE statements. ITERATE means “do the loop again.”

Example:

CREATE PROCEDURE doiterate(p1 INT)
BEGIN
  label1: LOOP
    SET p1 = p1 + 1;
    IF p1 < 10 THEN ITERATE label1; END IF;
    LEAVE label1;
  END LOOP label1;
  SET @x = p1;
END
