SQL Server 企业管理器 - 批量删除表和更改表的所有权

Question

我几乎没有使用 SQL Server 的企业管理器的经验，所以我不确定这是否可能（或者希望简单得可笑！）

在导入数据库期间，发生了一些事情，每个表都重复了自己，但有两个重要的区别。

第一个是两个表上的 Owner 不同，第二个是其中一个副本上只复制了结构。

Sod 定律表明数据当然存储在错误的人拥有的表上，所以我的问题是我是否可以快速删除一个用户拥有的所有表，我是否可以快速更改所有其他表的所有权以将它们带来排队。

有足够多的表格，自动化将是我长期的首选！

Answer 1

declare @emptyOwner varchar(20)
declare @wrongOwner varchar(20)
declare @emptyOwnerID bigint
declare @wrongOwnerID bigint
declare @tableName nvarchar(255)

set @emptyOwner = 'dbo'
set @wrongOwner = 'guest'

select @emptyOwnerID = (select uid from sysusers where name = @emptyOwner)
select @wrongOwnerID = (select uid from sysusers where name = @wrongOwner)

select name as tableName
into #tempTable
from systables
where type='U'
and exists (select 1 from systables where type = 'U' and uid = @emptyOwnerID)
and exists (select 1 from systables where type = 'U' and uid = @wrongOwnerID)

declare @dynSQL nvarchar(MAX)

declare ownme cursor for
  select tableName from #tempTable

open ownme
fetch next from ownme into @tableName

while @@FETCH_STATUS = 0
begin
    @dynSQL = 'DROP TABLE [' + @emptyOwner + '].[' + @tableName + ']'
    exec(@dynSQL)

    @dynSQL = 'sp_changeobjectowner ''[' + @wrongOwner + '].[' + @tableName + ']'',''' + @emptyOwner + ''''
    exec(@dynSQL)

    fetch next from ownme into @tableName
end

close ownme
deallocate ownme

有关更改所有权，请参阅：SQL Table Ownership Changes, Quick and Easy

上面链接给出的代码是：

DECLARE @old sysname, @new sysname, @sql varchar(1000)

SELECT
  @old = 'oldOwner_CHANGE_THIS'
  , @new = 'dbo'
  , @sql = '
  IF EXISTS (SELECT NULL FROM INFORMATION_SCHEMA.TABLES
  WHERE
      QUOTENAME(TABLE_SCHEMA)+''.''+QUOTENAME(TABLE_NAME) = ''?''
      AND TABLE_SCHEMA = ''' + @old + '''
  )
  EXECUTE sp_changeobjectowner ''?'', ''' + @new + ''''

EXECUTE sp_MSforeachtable @sql
