SQL 中 IN 子句中区分大小写的匹配

Question

I have 2 rows in my table like this我的表中有 2 行像这样

I want a case sensitive comparison.我想要区分大小写的比较。

I wrote a query like this我写了一个这样的查询

select *  
from table1 
where name in ('charlie', 'Frank') COLLATE Latin1_General_CS_AS;

but it is not working.但它不起作用。 What should be the query?查询应该是什么？

Answer 1

You need to change your column to case sensitive.您需要将列更改为区分大小写。 Something like:就像是：

ALTER TABLE table1
ALTER COLUMN name VARCHAR(100) 
COLLATE SQL_Latin1_General_CP1_CS_AS
