Question

I have the following subqueries, and they are throwing an error

 select ts.id,(CONCAT(ts.first_name, ' ', ts.last_name),
 (    select SUM(hours*pay)

   from 
 PTAddedApp aa 
   where 
   aa.tutor_id = ts.id
   and year(aa.date) = year(now())
   and month(aa.date) = month(now())


 ),
 (select SUM(nt.hours*nt.rate)
   from PT_NT_Work_Hours nt 
   where 
   nt.tutor_id = ts.id
   and year(nt.date) = year(now())
   and month(nt.date) = month(now())
 ) 

 from PT_Tutors ts

I get the following error message. I assume that I am doing something daft-
1064 – You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘from PT_Tutors ts’ at line 21

I posted a similar questions to see if I should use joins instead, and they pointed me back to subqueries, so I’m hoping someone can let me know what I am doing wrong.

Answer 1

You open 2 brackets near your concat function but only close 1. Remove the bracket before ‘CONCAT’

select ts.id,CONCAT(ts.first_name, ' ', ts.last_name),
 (    select SUM(hours*pay)

   from 
 PTAddedApp aa 
   where 
   aa.tutor_id = ts.id
   and year(aa.date) = year(now())
   and month(aa.date) = month(now())


 ),
 (select SUM(nt.hours*nt.rate)
   from PT_NT_Work_Hours nt 
   where 
   nt.tutor_id = ts.id
   and year(nt.date) = year(now())
   and month(nt.date) = month(now())
 ) 

from PT_Tutors ts
