sql中的越南字符选择像

Question

When I search with the following query

Select * From [table] WHERE Name like '%Hà Nội T&T%'

in my mssql database I get no results , even though I'm sure it exists in the db.

I seem to have trouble with characters like ộ, ẫ, and Đ .

I have tried changing collation-settings but nothing helps.

Any suggestions?

Answer 1

尝试：

Select * From [table] WHERE Name like N'%Hà Nội T&T%'

Answer 2

You need to alter your column containing Vietnamese characters.

ALTER TABLE [table] ALTER COLUMN name NVARCHAR(100) COLLATE Vietnamese_CI_AS

And then do

SELECT * FROM [table] WHERE name LIKE '%Hà Nội%'

Try changing connection encoding using:

SET character_set_client = charset_name;

Also please do not use Latin1 encoding, try switching to UTF8. Here is a FAQ for Vietnamse Unicode: http://vietunicode.sourceforge.net/main.html
