php - Mysql Case Syntax - 


select * case_study order case when expiry_date_case > curdate() 1 end when expiry_date_case null 2 desc end when expire_date_case < curdate() 3 desc end;

when trying run query getting error

#1064 - have error in sql syntax; check manual corresponds mysql server version right syntax use near 'when expiry_date_case null 2 desc end when expire_date_case < curdate() ' @ line 4

where doing wrong?

try

select * case_study order case when expiry_date_case > curdate() 1  when expiry_date_case null 2  when expire_date_case < curdate() 3 end desc

you have many end's , many desc's
