自动生成存储过程一

昨天领导让我把所有对数据的操作放在数据库进行,需要用到很多的存储过程,一想到要写那么多的存储过程,脑袋就两个大,于是在网上查找相关资料,竟然能找到自动生成存储过程的代码,不错,借用过来还真的能省不少时间呢,下面的存储过程Sp_GenInsert就可以帮我生成插入数据的存储过程。

调用sp_GenInsert存储过程的代码:
sp_GenInsert 'Employees', 'INS_Employees'

生成
sp_GenInsert存储过程代码:
CREATE procedure sp_GenInsert
@TableName varchar(130),
@ProcedureName varchar(130)
as
set nocount on

declare @maxcol int,
@TableID int

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
