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','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 ',
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 ',
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
