I have some complex queries that take a long time. Is there a tool that can tell me which steps in the query are taking the longest? I'm thinking of output similar to the EXPLAIN or EXPLAIN QUERY PLAN that would annotate the tables/indices/VM instructions with how long that portion of the query took.
I've tried using ANALYZE and it makes some of the queries faster but some slower. I've also noticed that SQLite really prefers subselects to joins. I've read the material on the web that describes the query optimizer but I still have a hard time knowing how to decide whether to force an order on operations and what that order should be. Does anyone have any hints?
