SQL Server编写存储过程小工具(三)

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 'knowsky.comset @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 /*＝＝＝＝＝＝＝源程序结束＝＝＝＝＝＝＝＝＝*/
