sql - How to list the tables in a SQLite database file that was opened with ATTACH?

What SQL can be used to list the tables, and the rows within those tables in a SQLite database file - once I have attached it with the ATTACH command on the SQLite 3 command line tool?

Answer

The .tables, and .schema "helper" functions don't look into ATTACHed databases: they just query the SQLITE_MASTER table for the "main" database. Consequently, if you used

ATTACH some_file.db AS my_db;

then you need to do

SELECT name FROM my_db.sqlite_master WHERE type='table';

Note that temporary tables don't show up with .tables either: you have to list sqlite_temp_master for that:

SELECT name FROM sqlite_temp_master WHERE type='table';
