SQL - retain ordering based on the query params

Question

I\'m trying to perform a SELECT with an IN clause and I would like to be able to have the results returned in the same order as the elements in my list

Answer 1

If you want to go with DECODE to assign a numerical sort order:

SELECT ID FROM tbl WHERE ID IN (2,3,1)
ORDER BY DECODE(ID, 2, 1, 3, 2, 3)
