Question

Does Sqlite create a “query plan” for the complex queries? (I know mysql creates one and chooses the best of different available combination to execute the query). Is there any way i can get last_query_cost as i usually get in mysql. i am trying to migrate from mysql to sqlite due to some resource requirement for my application.

SQLite supports the EXPLAIN keyword, like MySQL, but syntax is slightly different:

EXPLAIN QUERY PLAN SELECT col FROM YOUR_TABLE
