脚本宝典收集整理的这篇文章主要介绍了SQL SERVER编写存储过程小工具,脚本宝典觉得挺不错的,现在分享给大家,也给大家做个参考。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。
SQL Server编写存储过程小工具
以下是两个存储过程的源程序
/*===========================================================
语法: sp_GenInsert <Table Name>,<Stored Procedure Name>
以northwind 数据库为例
sp_GenInsert 'Employees', 'INS_Employees'
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。
=============================================================*/
CREATE procedure sp_GenInsert
@TableName varchar(130),
@Procedurename varchar(130)
as
set nocount on
declare @maxcol int,
@TableID int
--itlearner.COM
set @TableID = object_id(@TableName)
select @MaxCol = max(colorder)
From Syscolumns
where id = @TableID
select 'Create Procedure ' + rtrim(@ProcedureName) as tyPE,0 as colorder into #TempProc
union
select convert(char(35),'@' + syscolumns.name)
+ rtrim(systypes.name)
+ case when rtrim(systypes.name) in ('binary','char','nchar','nvarchar','varbinary','varchar') then '(' + rtrim(convert(char(4),syscolumns.length)) + ')'
when rtrim(systypes.name) not in ('binary','char','nchar','nvarchar','varbinary','varchar') then ' '
end
+ case when colorder < @maxcol then ','
when colorder = @maxcol then ' '
end
as type,
colorder
from syscolumns
join systypes on syscolumns.xtype = systypes.xtype
where id = @TableID and systypes.name <> 'sysname'
union
select 'AS',@maxcol + 1 as colorder
union
select 'INSERT INTO ' + @TableName,@maxcol + 2 as colorder
union
select '(',@maxcol + 3 as colorder
union
select syscolumns.name
+ case when colorder < @maxcol then ','
when colorder = @maxcol then ' '
end
as type,
colorder + @maxcol + 3 as colorder
from syscolumns
join systypes on syscolumns.xtype = systypes.xtype
where id = @TableID and systypes.name <> 'sysname'
union
select ')',(2 * @maxcol) + 4 as colorder
union
select 'VALUES',(2 * @maxcol) + 5 as colorder
union
select '(',(2 * @maxcol) + 6 as colorder
union
select '@' + syscolumns.name
+ case when colorder < @maxcol then ','
when colorder = @maxcol then ' '
end
as type,
colorder + (2 * @maxcol + 6) as colorder
from syscolumns
join systypes on syscolumns.xtype = systypes.xtype
where id = @TableID and systypes.name <> 'sysname'
union
select ')',(3 * @maxcol) + 7 as colorder
order by colorder
select type from #tempproc order by colorder
drop table #tempproc
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_Employees'
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。
===========================================================*/
CREATE procedure sp_GenUpdate
@TableName varchar(130),
@PrimaryKey varchar(130),
@ProcedureName varchar(130)
as
set nocount on
declare @maxcol int,
@TableID int
--itlearner.com
set @TableID = object_id(@TableName)
select @MaxCol = max(colorder)
from syscolumns
where id = @TableID
select 'Create Procedure ' + rtrim(@ProcedureName) as type,0 as colorder into #TempProc
union
select convert(char(35),'@' + syscolumns.name)
+ rtrim(systypes.name)
+ case when rtrim(systypes.name) in ('binary','char','nchar','nvarchar','varbinary','varchar') then '(' + rtrim(convert(char(4),syscolumns.length)) + ')'
when rtrim(systypes.name) not in ('binary','char','nchar','nvarchar','varbinary','varchar') then ' '
end
+ case when colorder < @maxcol then ','
when colorder = @maxcol then ' '
end
as type,
colorder
from syscolumns
join systypes on syscolumns.xtype = systypes.xtype
where id = @TableID and systypes.name <> 'sysname'
union
select 'AS',@maxcol + 1 as colorder
union
select 'UPDATE ' + @TableName,@maxcol + 2 as colorder
union
select 'SET',@maxcol + 3 as colorder
union
select syscolumns.name + ' = @' + syscolumns.name
+ case when colorder < @maxcol then ','
when colorder = @maxcol then ' '
end
as type,
colorder + @maxcol + 3 as colorder
from syscolumns
join systypes on syscolumns.xtype = systypes.xtype
where id = @TableID and syscolumns.name <> @PrimaryKey and systypes.name <> 'sysname'
union
select 'WHERE ' + @PrimaryKey + ' = @' + @PrimaryKey,(2 * @maxcol) + 4 as colorder
order by colorder
select type from #tempproc order by colorder
drop table #tempproc
