The following fragment shows how the LEAVE statement is used to leave a loop.

SET i = 1;
lbl:
LOOP
   INSERT
   INTO Counters ( number )
   VALUES ( i );
   IF i >= 10 THEN
      LEAVE lbl;
   END IF;
   SET i = i + 1
END LOOP lbl

The following example fragment uses LEAVE in a nested loop.

outer_loop:
LOOP
   SET i = 1;
   inner_loop:
   LOOP
      ...
      SET i = i + 1;
      IF i >= 10 THEN
         LEAVE outer_loop
      END IF
   END LOOP inner_loop
END LOOP outer_loop
