Re: Wrong index used in SELECT , ROW_NUMBER() OVER (PARTITION BY

The table has no primary key.

What problem are your table partitions meant to solve?

The optimiser seems to have decided that the (`client_id`,`end_date`,`division_id`) index wasn't worth the trouble. Can you prove the optimiser wrong?
