下面是个SQL SERVER编写存储过程小工具教程，撑握了其技术要点，学起来就简单多了。赶紧跟着小编一起来看看吧！
在开发数据库系统的过程中，经常要写很多的存储过程。为了统一格式和简化开发过程，我编写一些存储过程，用来自动生成存储过程。下面就为您简单介绍一下它们。其中一个用于生成Insert过程，另一个用于生成Update过程。
Sp_GenInsert
该过程运行后，它为给定的表生成一个完整的Insert过程。如果原来的表有标识列，您得将生成的过程中的SET IDNTITY_INSERT ON 语句手工删除。
语法如下
sp_GenInsert Table Name , Stored Procedure Name
以northwind 数据库为例
sp_GenInsert Employees, INS_Employees
最后会生成一个Insert存储过程。利用它，您可以作进一步的开发。
Sp_GenUpdate
它会为一个表生成update存储过程。语法如下：
sp_GenUpdate Table Name , Primary Key , Stored Procedure Name
以northwind 数据库为例
sp_GenUpdate Employees,EmployeeID,UPD_Employees
运行后生成如下所示的存储过程：
Create Procedure UPD_Employees
@EmployeeID int
@LastName nvarchar(40) ,
@FirstName nvarchar(20) ,
@Title nvarchar(60) ,
@TitleofCourtesy nvarchar(50) ,
@BirthDate datetime ,
@HireDate datetime ,
@Address nvarchar(120) ,
@City nvarchar(30) ,
@Region nvarchar(30) ,
@PostalCode nvarchar(20) ,
@Country nvarchar(30) ,
@HomePhone nvarchar(48) ,
@Extension nvarchar(8) ,
@Phote image ,
@Notes ntext ,
@ReportsTo int ,
@PhotoPath nvarchar(510)
AS
UPDATE Employees
SET
LastName = @LastName,
FirstName = @FirstName,
Title = @Title,
TitleofCourtesy = @TitleofCourtesy,
BirthDate = @BirthDate,
HireDate = @HireDate,
Address = @Address,
City = @City,
Regin = @Regin,
PostalCode = @PostCode,
Country = @Country,
HomePhone = @HomePhone,
Extension = @Extension,
Photo = @Photo
Notes = @Notes，
ReportsTo = @ReportsTo,
PhotoPath = @PhotoPath
WHERE EmployeeID = @EmployeeID
使用以上的两个存储过程，节省了我不少时间。特别是在改变了表结构后，重新构造各个存储过程的过程中。您可以改写这两个程序，来自动生成别的存储过程。
