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。
