Conditional ordering for Latin and English Names in SQLite - mysql

Question

I have a table 'Employee' which has column DevId, Id, FName, FNamePinYin.
FName will have both Chinese and English contact names. Now as per requirement I could manage to get contacts in below order:
FName FNamePinYin
爱华 杨 AIHUA YANG
安国华 ANGUOHUA
Anguohua ANGUOHUA
Aihua Yang AIHUA YANG
爸 BA
波 小 BO BEI BI XIAO
毕慧 BIHUI
Bin Guo BIN GUO
Bihui BIHUI
Ba BA
Using below query:
Select FName, SortString
from Employee
where Id in (SELECT Id
FROM EMP1
WHERE '1' = DevId
ORDER BY FnamePinYin
LIMIT 500 OFFSET 0)
ORDER BY substr(FnamePinYin,1,1) , Lower(FName) DESC
Now the problem is that contact names are not sorted in ascending order.
Note: Here Lower(FName) DESC is required to get Chinese names to be displayed first in each alphabet's category.
My desired output:
FName FNamePinYin
爱华 杨 AIHUA YANG
安国华 ANGUOHUA
Aihua Yang AIHUA YANG
Anguohua ANGUOHUA
爸 BA
波 小 BO BEI BI XIAO
毕慧 BIHUI
Ba BA
Bihui BIHUI
Bin Guo BIN GUO
FNamePinYin is English equivalent of Chinese names.
Can anyone help me get the result I want?

Answer 1

Your question is still not entirely clear, but based on your statement that "both Chinese and English Name should be in Acceding order" "in each category (A-Z)", then the following should do what I think you want:
select *
from Employee
where Id in (SELECT Id
FROM PBAPL1
WHERE '1' = DevId
ORDER BY FnamePinYin
LIMIT 500 OFFSET 0)
order by substr(FNamePinYin,1,1), (substr(FName,1,1) < 'zz'), FName;
