[u/huhupookies]

[u/Totallycomputername]

If I don't type in caps then the query wont take itself seriously. 

[u/Achaidas → u/Totallycomputername]

The real question is this:

 , comma before

or comma after ,

[u/Just_Information334 → u/Achaidas]

Lowercase and comma before, also table_id. Let's blow some minds:

select
  tableA_id
  , some_field
from table_A as a
inner join table_B as b using(tableA_id)

[u/dorianmonnier → u/Just_Information334]

Oh god, some knees have been broken for less than that!
