I have a simple SQL query in PostgreSQL 8.3 that grabs a bunch of comments. I provide a sorted list of values to the IN construct in the WHERE clause:

SELECT * FROM comments WHERE ( IN (1,3,2,4));

This returns comments in an arbitrary order which in my happens to be ids like 1,2,3,4.

I want the resulting rows sorted like the list in the IN construct: (1,3,2,4).

How to achieve that?

It'll be quite easy to do with VALUES (), () which is introduced in PostgreSQL 8.2.

Use the below query:

select c.*

from comments c

join (






) as x (id, ordering) on =

order by x.ordering
