鉴于大家对SQL SERVER十分关注，我们编辑小组在此为大家搜集整理了“MSSQL Server编写存储过程小工具(三)”一文，供大家参考学习!
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
