存储过程可以使用CREATE PROCEDURE语句创建。CREATE PROCEDURE语句的基本语法如下: 代码语言:javascript 代码运行次数:0 AI代码解释 CREATEPROCEDUREprocedure_name([parameter1 datatype1,parameter2 datatype2,...])[characteristics]BEGIN--SQL语句集合END; procedure_name是存储过程的名称。 parameter1, parameter2, ......

方法/步骤 1 1、打开MySqlWorkbench登录页面，输入密码，点击登录按钮 2 2、进入主页面，点击左上方的sql+按钮，如图所示：3 3、创建存储过程：create procedure procedure_name([procedure_parameter …..])routine_bodyprocedure_parameter：表示存储过程的参数，3种参数类型：in输入参数：只能传入，out输出参数，inout...
I have 2 input parameters namely entityname,state.i am passing as ('entity1,CA,NY',',') as the delimited in parameter value. I am able to insert the delimited values into the temp table. This below is the select statement i have written in the procedure. select entityname,state ...
In MySQL, a parameter has one of three modes IN, OUT or INOUT. IN –is the default mode. When you define an IN parameter in a stored procedure, the calling program has to pass an argument to the stored procedure. In addition, the value of an IN parameter is protected. It means ...
mysql的profile指标解读 mysql的procedure 一. 存储过程(PROCEDURE) 存储过程(Stored Procedure)是一种在数据库中存储复杂程序,以便外部程序调用的一种数据库对象。 存储过程是为了完成特定功能的SQL语句集,经编译创建并保存在数据库中,用户可通过指定存储过程的名字并给定参数(需要时)来调用执行。
CREATE PROCEDURE sp_name([proc_parameter[,...]])…… 2、确保参数的名字不等于列的名字,否则在过程体中,参数名被当做列名来处理 建议: 输入值使用in参数。 返回值使用out参数。 inout参数就尽量的少用。 三、变量 1. 变量定义 局部变量声明一定要放在存储过程体的开始: ...
