自动生成对表进行插入和更新的存储过程的存储过程

2006-12-01 22:37 701 查看
我找到了两个存储过程,能自动生成对一个数据表的插入和更新的存储过程,现在奉献给大家!
用法,先把它们入数据库,执行,拷贝以table形式出现的结果,此时剪贴板里的内容就是你想要的存储过程。

 

插入:

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

更新:

Create procedure sp_GenUpdate
@TableName varchar(130),
@PrimaryKey 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 '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
