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

I don't know if there is an elegant (or short) solution for this.

If you can build the query dynamically, the following should work:

WITH numbers AS (
   SELECT 1 as sort_order, 'B123' as order_no FROM DUAL
   union all
   SELECT 2 as sort_order, 'B483' as order_no FROM DUAL
   union all
   SELECT 2 as sort_order, 'B100' as order_no FROM DUAL
   union all
   SELECT 2 as sort_order, 'B932' as order_no FROM DUAL
)
SELECT orders.*
FROM numbers  
  LEFT JOIN orders ON orders.ord_no = numbers.ord_no
ORDER BY numbers.sort_order
