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

There are a few steps to see the tables in an SQLite database:

  1. List the tables in your database:

    .tables
    
  2. List how the table looks:

    .schema tablename
    
  3. Print the entire table:

    SELECT * FROM tablename;
    
  4. List all of the available SQLite prompt commands:

    .help
    

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';

It appears you need to go through the sqlite_master table, like this:

SELECT * FROM dbname.sqlite_master WHERE type='table';

And then manually go through each table with a SELECT or similar to look at the rows.

The .DUMP and .SCHEMA commands doesn't appear to see the database at all.
