我有一张存储汽车登记号的表格， 但有些注册号是西里尔文。如果我搜索注册号“XX0000XX”，其中“X”是拉丁文，而表中的一个或多个“X”是西里尔文，则什么也找不到。 有没有办法写这个查询，例如：
Select from cars where reg_num = 'XX0000XX'
以这样一种方式，它也可以找到同时包含西里尔字母和拉丁字母的记录？在where 子句中，字符串是 100% 拉丁字母
【问题讨论】：
WHERE 子句中的字符串不是已经出现在两个字母表中了吗？这里的长期解决方案是选择一个涵盖所有数据的排序规则。
如果您使用 MS SQL。可以使用音译功能
GO
/****** Object: UserDefinedFunction [dbo].[TransLit] Script Date: 05.04.2017 10:25:38 ******/
SET ANSI_NULLS ON

SET QUOTED_IDENTIFIER ON

ALTER FUNCTION [dbo].[TransLit]
(
@@String VarChar(max)
)
RETURNS VarChar(max)
AS
BEGIN
DECLARE @TransTable TABLE(
Rus Char
,Lat VarChar(2)
)INSERT @TransTable SELECT 'А','A'
UNION ALL SELECT 'Б','B'
UNION ALL SELECT 'В','V'
UNION ALL SELECT 'Г','G'
UNION ALL SELECT 'Д','D'
UNION ALL SELECT 'Е','E'
UNION ALL SELECT 'Ё','YO'

UNION ALL SELECT 'Ы','Y'
UNION ALL SELECT 'Ь',''''
UNION ALL SELECT 'Э','E'
UNION ALL SELECT 'Ю','YU'
UNION ALL SELECT 'Я','YA'
DECLARE @Result VarChar(max)
SET @Result = @@String
SELECT @Result = Replace(@Result,Upper(Rus) COLLATE Cyrillic_General_CS_AS,Upper(Lat)) FROM @TransTable WHERE @@String LIKE '%' + Rus + '%'
SELECT @Result = Replace(@Result,Lower(Rus) COLLATE Cyrillic_General_CI_AS,Lower(Lat)) FROM @TransTable WHERE @@String LIKE '%' + Rus + '%'
RETURN @Result
END
然后是你的脚本
Select * from cars where TransLit(reg_num) = 'XX0000XX'
在“XX0000XX”中使用拉丁文。
【讨论】：
Here是这个问题的T-SQL解决方案。主要思想是您必须用拉丁文 C、X、H 替换所有俄语 С、Х、Н 等。这里有所有类似的字符对都用于此功能。您可以编写自己的函数，将每对中的第一个字符替换为第二个字符。
