How to ORDER BY with different columns as one column?

Question

I\'ve got the following code below:

$db = $this->database[GDB];
$num_rows = $db->doQuery(\'SELECT TOP 100 strUserId, TotalTime, Nation, LoginDT FROM USERDA         


        

Answer 1

Have you tried

SELECT TOP 100 strUserId, TotalTime + (time() + 7200 - LoginDT) as
newTotalTime, Nation, LoginDT FROM USERDATA WHERE Authority IN(1, 2)
ORDER BY newTotalTime DESC
