Use the command "EXPLAIN QUERY PLAN {your sql command}". This will give
you a high level overview of all the tables being accessed, and which
indices (if any) will be used for each.
For a simple query like your example, SQLite will almost certainly use
an index on "id" if one is available. You can use above to verify this.
