ERROR:The database could not be exclusively locked to perform the operation

今天在导数据时遇到几个问题,因为一个是英文操作系统,一个是中文操作系统,两个默认的不一样。我想现在就统一在数据库级别将中文的那个Collation 从 Chinese_PRC_CI_AS 改为 SQL_Latin1_General_CP1_CI_AS(英文系统默认)。

但当我运行:

ALTER DATABASE QinBide COLLATE SQL_Latin1_General_CP1_CI_AS

报出错误如下:

Msg 5030, Level 16, State 2, Line 1
The database could not be exclusively locked to perform the operation.
Msg 5072, Level 16, State 1, Line 1
ALTER DATABASE failed. The default collation of database 'XXXX' cannot be set to Chinese_PRC_CI_AS.

所在环境:

OS:  Windows 7 Professional English X64

DB: Sql Server 2008 R2

 

解决办法:

ALTER DATABASE QinBide SET SINGLE_USER WITH ROLLBACK IMMEDIATE
go

ALTER DATABASE QinBide COLLATE SQL_Latin1_General_CP1_CI_AS

go

ALTER DATABASE QinBide SET MULTI_USER
go

不过还有另外一个问题,对于原有的数据表字段,对应的Collation也是 Chinese_PRC_CI_AS,但我不知道如何统一一次性修改,由于表的数量不多,我暂时就直接进入各个表进行修改(下回请教公司DBA一下):

列属性 –> Collation –> Restore Default
