Question

Here’s a query:

SELECT * 
  FROM table
 WHERE id = 1
    OR id = 100
    OR id = 50

Note that I provided the ids in this order: 1,100,50.

I want the rows to come back in that order: 1,100,50.

Currently, i comes back 1,50,100 – basically in ascending order. Assume the rows in the table were inserted in ascending order also.

Answer 1

You can just do this with ORDER BY:

ORDER BY
   id = 1 DESC, id = 100 DESC, id = 50 DESC

0 is before 1 in ORDER BY.
