Room user configurable order by queries

Question

I am migrating an app to use Room from normal Sqlite and one part that I am having trouble with is that there are several queries that have an orde

Answer 1

I'm facing the same problem right now. The thing that can be done is to use CASE:

SELECT * FROM Table
ORDER BY 
CASE WHEN :parameter = 1 THEN Column END ASC,
CASE WHEN :parameter = 2 THEN Column2 END DESC

But I'm assuming you are using a ViewModel as well, so you will probably have to reinitialise it every time. I think this way is a little bit better than writing 15 queries, maybe not as compact though.

This answer also has a nice example, but the logic is reversed I believe.
