Re: Is the query order guaranteed using Btree indexes and no ORDER BY

From the literature the below query rows/results should be ordered by columns c1, c2, c10 where c10 may have 1 or more distinct values.

Eh? What literature is that?

A fundamental rule of relational databases (eg EF Codd's rule 8) is that query order is undefined unless specified.

If you want to specify order, add an Order By clause.
