This article describes how to modify a stored procedure in SQL Server by using SQL Server Management Studio or Transact-SQL. Limitations Transact-SQL stored procedures cannot be modified to be CLR stored proced
存储过程(stored procedure)是一组为了完成特定功能的SQL语句集合,经编译后存储在服务器端的数据库中,利用存储过程可以加速SQL语句的执行。 自定义存储过程,由用户创建并能完成某一特定功能的存储过程,存储过程既可以有参数又有返回值,但是它与函数不同,存储过程的返回值只是指明执行是否成功, 存储过程并不能像函数那...
触发器(trigger)是个特殊的存储过程,它的执行不是由程序调用,也不是手工启动,而是由个事件来触发,比如当对一个表进行操作(insert,delete,update)时就会激活它执行。 SQL Server 包括三种常规类型的触发器:DML 触发器、DDL 触发器和登录触发器。 DML触发器:当数据库中表中的数据发生变化时,包括insert,update,delet...
--1、 不带参数的存储过程:创建一个存储过程,查看所有读者的姓名、可借本数、可借天数和已借书本数。 create procedure usp_selelctReader as select rdName,canLendQty,canLendDay,rdBorrowQty from Reader, ReaderType where Reader.rdType=ReaderType.rdType --测试执行 exec usp_selelctReader 1. 2. 3. ...
Asysadmin可以使用sp_procoption来停止在 SQL Server 启动时自动执行的过程。 在SSMS 中,连接到数据库引擎。 在标准工具栏中,选择“新建查询”。 将以下命令输入到查询窗口中。 SQL EXEC sp_procoption @ProcName = N'<stored procedure name>' , @OptionName = 'startup' , @OptionValue = 'off'; GO ...
存储过程(Stored Procedure)是一组为了完成特定功能的SQL语句集,经编译后存储在数据库中,用户通过指定存储过程的名字并给定参数(如果该存储过程带有参数)来调用执行它。外部程序可以直接调用数据库里面定义好的存储过程,另外数据库内部的触发器(trigger)、或者其他存储过程也可以调用它。
Extended stored procedures will be removed in a future version of SQL Server. Don't use this feature in new development work, and modify applications that currently use this feature as soon as possible. Create CLR procedures instead. This method provides a more robust and secure alternative to ...
There are different ways to execute a stored procedure. The first and most common approach is for an application or user to call the procedure. Another approach is to set the stored procedure to run automatically when an instance of SQL Server starts. ...
