BEGIN and END Statements

BEGIN and END statements group statements in procedures with more than one SQL statement. Declarations can be made only within a BEGIN ... END block. You can define a label for the block to clarify your code. The labels must match exactly. yourLableName: BEGIN <SQL statement>; END yourLableName mysql> mysql> DELIMITER // mysql> CREATE FUNCTION myProc (cost DECIMAL(10,2))     -> RETURNS DECIMAL(10,2)     ->     -> SQL SECURITY DEFINER     ->     -> tax: BEGIN     ->     DECLARE order_tax DECIMAL(10,2);     ->     SET order_tax = cost * .05;     ->     RETURN order_tax;     -> END     -> // Query OK, 0 rows affected (0.00 sec) mysql> DELIMITER ; mysql> mysql> select myProc(123.45); +----------------+ | myProc(123.45) | +----------------+ |           6.17 | +----------------+ 1 row in set, 1 warning (0.00 sec) mysql> mysql> drop function myProc; Query OK, 0 rows affected (0.00 sec) mysql>
