WHILE Statement
[begin_label:] WHILE search_condition DO statement(s) END WHILE [end_label] |
The statements within a WHILE statement are repeated as long as the
search_condition is true.
begin_label and end_label must be the same, if both are
specified.
For example:
CREATE PROCEDURE dowhile()
BEGIN
DECLARE v1 INT DEFAULT 5;
WHILE v1 > 0 DO
...
SET v1 = v1 - 1;
END WHILE;
END
