between "Chinese_PRC_CI_AS" and "SQL_Latin1_General_CP1_CI_AS"的问题

某网友的解决办法: 该办法在使用where或inner join时没有区别
DataTable t = Luo.Base.ExecuteSql4Ds("select [游船时刻表].*,[游船].[星级],[游船].[向上价格],[游船].[向下价格],[游船].[静态文件名] from [游船时刻表] inner join [游船] on [游船时刻表].[游船名称] COLLATE SQL_Latin1_General_CP1_CI_AS =[游船].[游船名称] order by [游船时刻表].[游船名称]").Tables[0];

或DataTable father_table = Luo.Base.ExecuteSql4Ds("select [行程类型].[行程类型名称] from [行程类型] where [行程类型].[行程类型名称] COLLATE SQL_Latin1_General_CP1_CI_AS in(select [行程].[行程类型] from [行程])").Tables[0];
DataTable son_table = Luo.Base.ExecuteSql4Ds("select * from [行程] where [行程].[行程类型] COLLATE SQL_Latin1_General_CP1_CI_AS in(select [行程类型].[行程类型名称] from [行程类型] where [行程类型].[行程类型名称] COLLATE SQL_Latin1_General_CP1_CI_AS in(select [行程].[行程类型] from [行程]))").Tables[0];
father_table.TableName = "t1";
son_table.TableName = "t2";
DataSet ds = new DataSet();
ds.Tables.Add(father_table.Copy());
ds.Tables.Add(son_table.Copy());
ds.Relations.Add("myrelation", ds.Tables[0].Columns["行程类型名称"], ds.Tables[1].Columns["行程类型"]);

Repeater_tourtype.DataSource = ds.Tables[0];
Repeater_tourtype.DataBind();

以下是在网上搜索到的：

　　最近在测试程序的时候，因为我总是不停地换数据库测试，发现了一个问题，在有些库里面运行正常的程序，在另外一些库中就会出现错误，提示为：
　　Msg 468, Level 16, State 9, Line 1
　　Cannot resolve the collation conflict between
　　 "Chinese_PRC_CI_AS" and "SQL_Latin1_General_CP1_CI_AS"
　　in the equal to operation.
　　
　　出现这样的错误的代码中，都有创建临时表“create table #tmp（。。。）”这样的操作，因为数据库都是从标准测试库中备份恢复出来的，估计是因为字符集不一样的原因。解决的方法是在创建临时表的时候增加collate database_default。
　　例如：
　　create table #tmp (code nvarchar(10) collate database_default)

另一种说法：
Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Chinese_PRC_CI_AS" in the equal to operation??
使用的数据库是英文的是不是语言问题怎么解决？？

1排序规则冲突。什么操作时引起的？
2看看你表的字段排序规则是否一致。
3再加上Collate子句好了
原因是有两种排序规则，必须显示指定其中一种
把语句贴出来更好说明一点
4操作时指定COLLATE
5将表结构里字段排序规则改为一致就可以了
6WHERE A.Column COLLATE SQL_Latin1_General_CP1_CI_AS = B.Column

第三种说法：

在SQL Server端不能将汉字作为查询条件

我使用一个系统，开发工具为PB9.0，数据库为SQL Server2000英文版，我们的用户在前端可正
常输入汉字，我也可在SQL Query Analyzer查看到汉字，但当我在SQL Query Analyzer上用汉字
作为查询条件时，就查不出记录，如下查询语句：
select * from employee where empname='张华'.
但是在PB9.0端可以查询。
请问：有谁知道怎样解决及什么原因？谢谢！
set quoted_identifier on 开启分隔标示符。
谢谢KAKAJE的回答，我设定了set quoted_identifier on, 但执行以汉字为查询条件的语句时，
仍然不能返回记录，如下语句：
select * from employee where empname='张华' OR
select * from employee where empname=N'张华'.
请问：我还可以怎样做？及设定set quoted_identifier on 对数据库是否有影响？谢谢！
你试试这个行不行

select * from employee where ename like '%张华%'
like语句也是不可以的，我想应该是SQL Server不能正确转化汉字的内码，但我不知道应怎样做
？
what is the collation of the employee table name column,
it should like:
chinese_prc_......

The column's collation is: SQL_Latin1_General_CP1_CI_AS, and this is database
defualt value. because the SQL Server2000 is been upgraded from SQL Server6.5, I use
all default setting according to SQL Server6.5. and I don't dare modifing the
collation because I worry about there are any error caused.

SQL_Latin1_General_CP1_CI_AS is usually used from english edition. You can set your
NAME table as
nchar or nvarchar data type, and use Chinese_Prc_CI_AS as the column collation. It
will work fine for both english and chinese name.
When you insert/query data, always use N'张华' as your constant expression, since
it will treat it as a unicode string instead of a ANSI string.

Thank you: qingsongy. Now My database exists the following some case:
1. The collation of Database: SQL_Latin1_General_CP1_CI_AS . and I don't know
whether can change its collation to Chinese_Prc_CI_AS and how to change?
2. When I want to change the column: empname's collation from <database Default> to
Chinese_Prc_CI_AS, there is a error encountered and can't be changed, the error as
follows:
'employee' table
- Unable to modify table.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Line 4: Incorrect syntax
near 'COLLATE'.
Please ask how to solve it?
3. There isn't Chinese_Prc_CI_AS the option in [SQL Collation], Only [Windows
Collation] includes it. Please ask the difference between [SQL Collation] and
[Windows Collation]?
At fact, I made a testing database and the testing database's collation is
Chinese_Prc_CI_AS, then I copy all data from living database. On SQL Server I can
enquiry relevant records by chinese enquiry condition.
By the way, My SQL Server IS SQL Server2000 English Standard Edition.
