mysql顺序依次显示大写结果

Question

我有一个简单的mysql查询，从表中提取AES_ENCRYPTED个名字， 我希望结果显示在alphabetical order，但问题是结果首先显示资本结果 .. 我的意思是

A

B

a

b

但我想要

A

a

B

b

这是我的query ..

select 
id as id,
AES_DECRYPT(fname,'$_ENCKEY') as fname1,
AES_DECRYPT(lname,'$_ENCKEY') as lname 
from patient 
order by fname1 ASC 

我也试过LOWER, UPPER, UCASE etc....但没有运气......

我正在使用 PDO ...

Answer 1

尝试将AES_ENCRYPT的返回值强制转换为CHAR。

   select 
   id as id,
   CAST(AES_DECRYPT(fname,'$_ENCKEY') AS CHAR CHARACTER SET latin1 ) as fname1,
   AES_DECRYPT(lname,'$_ENCKEY') as lname 
   from patient 
   order by fname1 collate latin1_general_cs

Answer 2

这是一个区分大小写的问题：

尝试：

select 
id as id,
AES_DECRYPT(fname,'$_ENCKEY') as fname1,
AES_DECRYPT(lname,'$_ENCKEY') as lname 
from patient 
order by fname1 COLLATE 'latin1_swedish_ci' ASC
