SQL SERVER编写存储过程小工具

　　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SETIDNTITY_INSERTON语句手工删除。

语法如下

sp_GenInsert<TableName>,<StoredProcedureName>

以northwind数据库为例

sp_GenInsertEmployees,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<TableName>,<PrimaryKey>,<StoredProcedureName>

以northwind数据库为例

sp_GenUpdateEmployees,EmployeeID,UPD_Employees

运行后生成如下所示的存储过程：

CreateProcedureUPD_Employees

@EmployeeIDint

@LastNamenvarchar(40),

@FirstNamenvarchar(20),

@Titlenvarchar(60),

@TitleofCourtesynvarchar(50),

@BirthDatedatetime,

@HireDatedatetime,

@Addressnvarchar(120),

@Citynvarchar(30),

@Regionnvarchar(30),

@PostalCodenvarchar(20),

@Countrynvarchar(30),

@HomePhonenvarchar(48),

@Extensionnvarchar(8),

@Photeimage,

@Notesntext,

@ReportsToint,

@PhotoPathnvarchar(510)

AS

UPDATEEmployees

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

WHEREEmployeeID=@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。
