MSSQL Server编写存储过程小工具(三)

核心提示:SQL
Server编写存储过程小工具功能:为给定表创建Update存储过程

USE [XXX] GO

SQL Server编写存储过程小工具 功能:为给定表创建Update存储过程 语法:
sp_GenUpdate Table Name,Primary Key,Stored Procedure Name 以northwind
数据库为例 sp_GenUpdate Employees,EmployeeID,UPD_澳门新葡萄京官网注册,Employees

QUOTED_IDENTIFIER ON GO

注释:如果您在Master系统数据库中创建该过程,那您就可以在您服务器上所有的数据库中使用该过程。
