13.6.5.8 WHILE Syntax

Contents
  1. [begin_label:] WHILE search_condition DO
  2.     statement_list
  3. 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:

  1. CREATE PROCEDURE dowhile()
  2. BEGIN
  3.   DECLARE v1 INT DEFAULT 5;
  4.  
  5.   WHILE v1 > 0 DO
  6.     ...
  7.     SET v1 = v1 - 1;
  8.   END WHILE;
  9. END;
