15.6.5.6 REPEAT Statement

Press CTRL+C to copy
[begin_label:] REPEAT statement_list UNTIL search_condition END REPEAT [end_label]

The statement list within a REPEAT statement is repeated until the search_condition expression is true. Thus, a REPEAT always enters the loop at least once. statement_list consists of one or more statements, each terminated by a semicolon (;) statement delimiter.

A REPEAT statement can be labeled. For the rules regarding label use, see Section 15.6.2, “Statement Labels”.

Example:

mysql> delimiter // mysql> CREATE PROCEDURE dorepeat(p1 INT) BEGIN SET @x = 0; REPEAT SET @x = @x + 1; UNTIL @x > p1 END REPEAT; END // Query OK, 0 rows affected (0.00 sec) mysql> CALL dorepeat(1000)// Query OK, 0 rows affected (0.00 sec) mysql> SELECT @x// +------+ | @x | +------+ | 1001 | +------+ 1 row in set (0.00 sec)
