我找到了兩個存儲過程，能自動生成對一個數(shù)據(jù)表的插入和更新的存儲過程，現(xiàn)在奉獻給大家！
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
