Question

Can i have 2 results within a single query?

For example:
I have the following query.

SELECT * 
FROM table1 JOIN table2 ON table1.id = table2.id 
WHERE table1.user_id = $var;

I want the first result is WHERE table1.user_id = $var.
The second result is loop without WHERE table1.user_id = $var.

Answer 1

Do you want the result on which the userid is equal to $var to be on top of the result on which userid is not equal to $var?

SELECT * 
FROM   table1 
       JOIN table2 
           ON table1.id = table2.id 
ORDER BY IF(table1.user_id = $var, 0 , 1) ASC
