Question

I want based on a value queried from another table order ASC or DESC.

So something like this:

SELECT *
FROM table
ORDER BY 
    CASE (SELECT sorting from table2 WHERE table2.id = ?)
        WHEN 1 THEN table.date ASC END 
        WHEN 0 THEN table.date DESC END
    END

Is anything like that available in MySQL?

I’ve seen for MS-SQL Server some solution: how to order 2 SQL Fields in asc and desc dynamically

EDIT: I just saw I made a mistake in the description, fixed.

Answer 1

order by if((select sorting from table2 where table2.id = ?) = 1,
  unix_timestamp(table.date), -unix_timestamp(table.date))

negation works if your column is numeric. if it’s a string, you might be able to find another function to map high values to low values…
