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

You can change your query to this

$num_rows = $db->doQuery('SELECT TOP 100 strUserId, TotalTime, Nation, LoginDT FROM USERDATA WHERE Authority IN(1, 2) ORDER BY (TotalTime + ('.time().' + 7200 - LoginDT)) DESC');

Please note that the query is concatenated with time() since it's a PHP function, not a SQL Server function.

This is the generated query

SELECT TOP 100 strUserId, TotalTime, Nation, LoginDT FROM USERDATA WHERE Authority IN(1, 2) ORDER BY (TotalTime + (1416132847 + 7200 - LoginDT)) DESC

Answer 2

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
