Re: [sqlite] Table has different rootpage in EXPLAIN and sqlite_master
You were correct David. The explain rootpage referred to an index and I was checking against the table rootpage. -- Sent from: http://sqlite.1065341.n5.nabble.com/ ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
Re: [sqlite] Table has different rootpage in EXPLAIN and sqlite_master
Hi David, The two queries were as follows explain select vCol,* from Race,Meta.vCols; and select * from meta.sqlite_master where type='table'; Sorry, I don’t have a copy of the unvacuumed db.

Do you have a copy of the weird version of the database still, or have a copy of the explain text and the sqlite_master contents? Was there another index or table whose root page is what was listed in the explain output? For example, were you expecting it to use the table, but it used a covering index instead? -Original Message- From: sqlite-users On Behalf Of x Sent: Monday, February 3, 2020 1:07 PM To: Discussion of SQLite Database Subject: [sqlite] Table has different rootpage in EXPLAIN and sqlite_master Differing by 1.
