批量删除存储过程和批量修改存储过程 修改:

 

三、技巧
1、1=1,1=2 的使用,在 SQL 语句组合时用的较多
“where 1=1” 是表示选择全部
“where 1=2”全部不选,
如:
if @strWhere !=”
begin set @strSQL = ‘select count(*) as Total from [‘ + @tblName + ‘]
where ‘ + @strWhere
end
else
begin
set @strSQL = ‘select count(*) as Total from [‘ + @tblName + ‘]’
end

因为一些网站是使用虚拟主机.用sql-server导数据上去的话.
数据库的用户默认是你登录的用户,不是dbo,有时就和本地产生不一致.

declare proccur cursor for select [name] from sysobjects where name
like ‘Foods_%’declare @procname varchar(100)declare @temp
varchar(100)open proccurfetch next from proccur into
@procnamewhile(@@FETCH_STATUS = 0)begin set @temp=’kcb_’+@procname
EXEC SP_RENAME @procname,@temp print(@procname + ‘已被删除’) fetch
next from proccur into @procnameendclose proccurdeallocate proccur

CREATE PROCEDURE dbo.ChangeObjectOwner
@CurrentOwner as NVARCHAR(128),–当前所有者
@NewOwner as NVARCHAR(128)–新所有者
AS 
DECLARE @Name   as NVARCHAR(128) 
DECLARE @Owner as NVARCHAR(128)
DECLARE @OwnerName as NVARCHAR(128) 

我们可以直接写成
set @strSQL = ‘select count(*) as Total from [‘ + @tblName + ‘]
where 1=1 ‘+ @strWhere

–功能说明:成批更改数据库所有者的对象 –作者:不详 –用法:exec
ChangeObjectOwner nmkspro,dbo –即可将所有nmkspro所有者的对象改为dbo所有
–运行成功后将提示:注意: 更改对象名的任一部分都可能破坏脚本和存储过程。
CREATE PROCEDURE dbo.ChangeObjectOwner @OldOwner as
NVARCHAR(128),–参数原所有者 @NewOwner as NVARCHAR(128)–参数新所有者 AS

详细实例

DECLARE curObject CURSOR FOR 
select ‘Name’   = name,
‘Owner’   = user_name(uid)
from sysobjects
where user_name(uid)=@CurrentOwner  –and   xtype=’p’
order by name 

2、收缩数据库
–重建索引 DBCC REINDEX DBCC INDEXDEFRAG
–收缩数据和日志 DBCC SHRINKDB DBCC SHRINKFILE

DECLARE @Name as NVARCHAR(128) DECLARE @Owner as NVARCHAR(128) DECLARE
@OwnerName as NVARCHAR(128)

批量修改表的所有者:

OPEN curObject
FETCH NEXT FROM curObject INTO @Name, @Owner
WHILE(@@FETCH_STATUS=0)
BEGIN   
if @Owner=@CurrentOwner 
begin
set @OwnerName = @CurrentOwner + ‘.’ + rtrim(@Name)
exec sp_changeobjectowner @OwnerName, @NewOwner
end  

3、压缩数据库 dbcc shrinkdatabase(dbname)
