Question

I have this mysql query:

SELECT * FROM `mytable` WHERE (condition 1) OR (condition 2) OR (condition3)

Can I make this query show the rows from condition 1, followed by the ones from condition2 and finally condition 3?

I did this by using UNION and it worked, but it’s slower (tested the query on my mysql) – actually it’s faster than the “OR” query if there are no duplicates but way slower if there are.

Ty!

Not sure if this would work for you:

SELECT * FROM `mytable` WHERE (condition 1) OR (condition 2) OR (condition3)
ORDER BY CASE WHEN condition=1 THEN 1 
         CASE WHEN condition=2 THEN 2
         CASE WHEN condition=3 THEN 3
         END
