Subject Re: [firebird-support] Help interpret plan
Author Svein Erling Tysvær
How many records are there in BUPD, are the other indexes in the plan selective and can you show us the query? Just wondering if it can be rewritten so that the query performs better (I assume the reason for you asking about the plan being that you have a query that is too slow).
