[begin_label
:] REPEATstatement_list
UNTILsearch_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 13.6.2,
"Statement Label Syntax".
Example:
mysql>delimiter //
mysql>CREATE PROCEDURE dorepeat(p1 INT)
->BEGIN
->SET @x = 0;
->REPEAT
->SET @x = @x + 1;
->UNTIL @x > p1 END REPEAT;
->END
->//
