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.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
