13.6.5.8 WHILE Syntax

[begin_label:] WHILE search_condition DO
    statement_list
END WHILE [end_label]

The statement list within a WHILE statement is repeated as long as the search_condition expression is true. statement_list consists of one or more SQL statements, each terminated by a semicolon (;) statement delimiter.

A WHILE statement can be labeled. For the rules regarding label use, see Section 13.6.2, “Statement Label Syntax”.

Example:

CREATE PROCEDURE dowhile()
BEGIN
  DECLARE v1 INT DEFAULT 5;

  WHILE v1 > 0 DO
    ...
    SET v1 = v1 - 1;
  END WHILE;
END;
