我如何去掉弦上的重音?

I have the following string

我有下面的字符串。

áéíóú

which I need to convert it to

我需要把它转换成?

aeiou

How can I achieve it? (I don't need to compare, I need the new string to save)

我怎样才能做到呢?(我不需要比较，我需要新的字符串来保存)

3 个解决方案

#1

Try using COLLATE:

试着用整理:

select 'áéíóú' collate SQL_Latin1_General_Cp1251_CS_AS

For Unicode data, try the following:

关于Unicode数据，请尝试以下操作:

select cast(N'áéíóú' as varchar(max)) collate SQL_Latin1_General_Cp1251_CS_AS

I am not sure what you may lose in the translation when using the second approach.

我不确定在使用第二种方法时，您在翻译过程中会失去什么。

It looks like œ is a special case, and we have to handle upper and lower case separately. You can do it like this (this code is a good candidate for a user-defined function):

œ似乎是一个特例,我们必须处理分别大写和小写。您可以这样做(此代码是用户定义函数的一个很好的候选):

declare @str nvarchar(max) = N'ñaàeéêèioô; Œuf un œuf'
select cast(
    replace((
        replace(@str collate Latin1_General_CS_AS, 'Œ' collate Latin1_General_CS_AS, 'OE' collate Latin1_General_CS_AS) 
    ) collate Latin1_General_CS_AS, 'œ' collate Latin1_General_CS_AS, 'oe' collate Latin1_General_CS_AS) as varchar(max)
) collate SQL_Latin1_General_Cp1251_CS_AS 
-- Output:
-- naaeeeeioo; Oeuf un oeuf

I had the same problem. In Greek for proper conversion to UPPER() you must suppress accent. Changing collation caused issues in other applications. Putting some REPLACE() functions I had more control on the behavior maintaining collation. Below is my ToUpperCaseGR function.

我也有同样的问题。在希腊语中，要正确地转换为UPPER()，你必须抑制重音。更改排序规则会在其他应用程序中引起问题。放置一些REPLACE()函数可以更好地控制行为维护排序。下面是ToUpperCaseGR函数。

    SET ANSI_NULLS ON
    GO
    SET QUOTED_IDENTIFIER ON
    GO

    create FUNCTION ToUpperCaseGR
    (
     @word nvarchar(max)
    )
    RETURNS nvarchar(max)
    AS
    BEGIN
        -- Declare the return variable here
        declare @res nvarchar(max)
        set @res = UPPER(@word)
        set @res = replace(@res,'Ά','Α')
        set @res = replace(@res,'Έ','Ε')
        set @res = replace(@res,'Ί','Ι')
        set @res = replace(@res,'Ή','Η')
        set @res = replace(@res,'Ό','Ο')
        set @res = replace(@res,'Ύ','Υ')
        set @res = replace(@res,'Ώ','Ω')


        -- Return the result of the function
        RETURN @res

    END
    GO

#3

Use this function:

使用这个函数:

CREATE FUNCTION [dbo].[F_RemoveDiacritics] (
 @String varchar(max)
)   RETURNS varchar(max)

AS BEGIN
DECLARE @StringResult VARCHAR(max);

select @StringResult= @String collate SQL_Latin1_General_Cp1251_CS_AS

return @StringResult


END
