让我们首先创建一个存储过程-mysql>DELIMITER//
mysql>CREATEPROCEDUREExtenddatesWithMonthdemo(INdate1datetime,INNumberOfMonthint)
->BEGIN
->SELECTDATE_ADD(date1,INTERVALNumberOfMonthMONTH)ASExtendDate;
->END;
->//
mysql>DELIMITER;
现在，使用help SHOW CREATE命令检查存储过程是否存在。
查询如下-mysql>SHOWCREATEPROCEDUREExtenddatesWithMonthdemo;
Thefollowingistheoutputdisplayingthedetailsofthestoredprocedurewecreatedabove:

借助CALL命令调用存储过程。查询如下-mysql>callExtenddatesWithMonthdemo('-02-13',6);
输出结果+---------------------+
|ExtendDate|
+---------------------+
|-08-1300:00:00|
