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

Question

What SQL can be used to list the tables, and the rows within those tables in an SQLite database file - once I have attached it with the

Answer 1

Use:

import sqlite3

TABLE_LIST_QUERY = "SELECT * FROM sqlite_master where type='table'"

Answer 2

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.

Answer 3

There is a command available for this on the SQLite command line:

.tables ?PATTERN?      List names of tables matching a LIKE pattern

Which converts to the following SQL:

SELECT name FROM sqlite_master
WHERE type IN ('table','view') AND name NOT LIKE 'sqlite_%'
UNION ALL
SELECT name FROM sqlite_temp_master
WHERE type IN ('table','view')
ORDER BY 1

Answer 4

To list the tables you can also do:

SELECT name FROM sqlite_master
WHERE type='table';

Answer 5

The ".schema" commando will list available tables and their rows, by showing you the statement used to create said tables:

sqlite> create table_a (id int, a int, b int);
sqlite> .schema table_a
CREATE TABLE table_a (id int, a int, b int);

Answer 6

.da to see all databases - one called 'main'

tables of this database can be seen by

SELECT distinct tbl_name from sqlite_master order by 1;

The attached databases need prefixes you chose with AS in the statement ATTACH e.g. aa (, bb, cc...) so:

SELECT distinct tbl_name from aa.sqlite_master order by 1;

Note that here you get the views as well. To exclude these add where type = 'table' before ' order'
