You do realize that format has nothing to do with how SQL Server stores datetime, right?

You can use <code>set dateformat</code> for each session. There is no setting for database only.

If you use parameters for data insert or update or where filtering you won't have any problems with that.

blocks|key|319553|text|您只能更改整个服务器上的语言，而不能更改单个数据库。但是，如果需要支持UK，则可以在所有输入和输出之前运行以下命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|319554|set+language+'british+english'|code-block|syntax|javascript|319555|或者，如果您在从应用程序输入数据时遇到问题，您可能需要考虑一种通用输入类型，如|319556|319557|+1-2008年12月-|blockquote|319558|319559|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|Q|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|R|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|S|8|@]|9|@]|A|$]]|$1|J|3|K|5|L|7|T|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|U|8|@]|9|@]|A|$]]|$1|N|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|O|$]]

You can only change the language on the whole server, not individual databases. However if you need to support the UK you can run the following command before all inputs and outputs:

<pre><code>set language 'british english'
</code></pre>

Or if you are having issues entering datatimes from your application you might want to consider a universal input type such as

<blockquote>
 1-Dec-2008
</blockquote>

blocks|key|647383|text|如果这确实是QA问题，并且您不能更改代码。在机器上安装一个新的服务器实例，并将语言设置为“英式英语”|type|unstyled|depth|inlineStyleRanges|entityRanges|data|647384|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

If this really is a QA issue and you can't change the code. Setup a new server instance on the machine and setup the language as "British English"

blocks|key|320441|text|为了避免处理这些非常无聊的问题，我建议您始终使用标准和惟一的SQL/ISO日期格式(YYYY)解析数据。然后，无论您的主服务器上或查询客户端上的日期参数是什么(本地日期设置可能与主服务器设置不同)，您的查询都将在国际范围内工作！|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|320442|entityMap^0|O|H|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

In order to avoid dealing with these very boring issues, I advise you to always parse your data with the standard and unique SQL/ISO date format which is YYYY-MM-DD. Your queries will then work internationally, no matter what the date parameters are on your main server or on the querying clients (where local date settings might be different than main server settings)!

blocks|key|635891|text|您可以使用SET+DATEFORMAT，如本例所示|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|635892|declare+@dates+table+(orig+varchar(50)+,parsed+datetime)

SET+DATEFORMAT+ydm;

SET+DATEFORMAT+ymd;
insert+into+@dates
select+'2008-09-01','2008-09-01'

select+*+from+@dates|code-block|syntax|javascript|635893|在解析XML数据时，需要在代码中指定日期格式。|635894|entityMap^0|5|E|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|S|8|@]|D|@]|E|$]]|$1|M|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|N|$]]

You could use SET DATEFORMAT, like in this example

<pre><code>declare @dates table (orig varchar(50) ,parsed datetime)

SET DATEFORMAT ydm;

insert into @dates
select '2008-09-01','2008-09-01'

SET DATEFORMAT ymd;
insert into @dates
select '2008-09-01','2008-09-01'

select * from @dates
</code></pre>

You would need to specify the dateformat in the code when you parse your XML data

blocks|key|647447|text|使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|647448|select+*+from+mytest
EXEC+sp_rename+'mytest.eid',+'id',+'COLUMN'

ALTER+TABLE+[dbo].[yourtablename]+ADD+DEFAULT+(getdate())+FOR+[yourfieldname]|code-block|syntax|javascript|647449|它100%25都能用。|647450|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Use:

<pre><code>select * from mytest
EXEC sp_rename 'mytest.eid', 'id', 'COLUMN'
alter table mytest add id int not null identity(1,1)
update mytset set eid=id
ALTER TABLE mytest DROP COLUMN eid

ALTER TABLE [dbo].[yourtablename] ADD DEFAULT (getdate()) FOR [yourfieldname]
</code></pre>

It's working 100%.

blocks|key|320452|text|对于Server+2008，运行：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|320453|EXEC+sp_defaultlanguage+'username',+'british'|code-block|syntax|javascript|320454|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

For SQL Server 2008 run:

<pre><code>EXEC sp_defaultlanguage 'username', 'british'
</code></pre>

blocks|key|319618|text|虽然不能为单个数据库设置默认日期格式，但可以更改用于访问此数据库的登录的默认语言：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|319619|ALTER+LOGIN+your_login+WITH+DEFAULT_LANGUAGE=British|code-block|syntax|javascript|319620|在某些情况下是有帮助的。|319621|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Although you can not set the default date format for a single database, you can change the default language for a login which is used to access this database:

<pre><code>ALTER LOGIN your_login WITH DEFAULT_LANGUAGE=British
</code></pre>

In some cases it helps.

I need to change the date format from US (mm/dd/YYYY) to UK (dd/mm/YYYY) on a single database on a SQL server machine.

How can this be done?

I've seen statements that do this for the whole system, and ones that do it for the session, but I can't change the code now as it will have to go through QA again, so I need a quick fix to change the date time format.

Update

I realize that the date time has nothing to do with how SQL Server stores the data, but it does have a lot to do with how it parses queries.

I'm chucking raw data from an XML file into a database. The dates in the XML file are in UK date format.
