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
