Thanks,All, To Tino,I want to order by IN condition "(6,3,4,10,7)".
To Sergio,my answer is "Yes".
To Kenny,I think this is not the result I want to get.
To Scott,In database,there are thousands of products.the select
query is generated by application,and it is not sure how many product_id
in condition,maybe the next query would be .........product_id in
(4,26,7,8,9,23,27,54)
Maybe,temp table is a solution,but that would be performance issue.
thanks
