How can I 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:

List the tables in your database: .tables List how the table looks: .schema tablename Print the entire table: SELECT * FROM tablename; 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.

---

To show all tables, use

SELECT name FROM sqlite_master WHERE type = "table"

To show all rows, I guess you can iterate through all tables and just do a SELECT * on each one. But maybe a DUMP is what you're after?

---

Use .help to check for available commands.

.table

This command would show all tables under your current database.

---

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

---

To list the tables you can also do:

SELECT name FROM sqlite_master
WHERE type='table';

---

Try PRAGMA table_info(table-name);
http://www.sqlite.org/pragma.html#schema

---

I use this query to get it:

SELECT name FROM sqlite_master WHERE type='table'

And to use in iOS:

NSString *aStrQuery=[NSString stringWithFormat:@"SELECT name FROM sqlite_master WHERE type='table'"];

---

According to the documentation, the equivalent of MySQL's SHOW TABLES; is:

The ".tables" command is similar to setting list mode then executing the following query:

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;

However, if you are checking if a single table exists (or to get its details), see LuizGeron's answer.

As of the latest versions of SQLite 3 you can issue:

.fullschema

to see all of your create statements.

---

The easiest way to do this is to open the database directly and use the .dump command, rather than attaching it after invoking the SQLite 3 shell tool.

So... (assume your OS command line prompt is $) instead of $sqlite3:

sqlite3> ATTACH database.sqlite as "attached"

From your OS command line, open the database directly:

$sqlite3 database.sqlite
sqlite3> .dump

---

Via a union all, combine all tables into one list.

select name
from sqlite_master 
where type='table'

union all 

select name 
from sqlite_temp_master 
where type='table'

---

Use:

import sqlite3

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

---

Since nobody has mentioned about the official reference of SQLite, I think it may be useful to refer to it under this heading:

https://www.sqlite.org/cli.html

You can manipulate your database using the commands described in this link. Besides, if you are using Windows OS and do not know where the command shell is, that is in the SQLite's site:

https://www.sqlite.org/download.html

After downloading it, click sqlite3.exe file to initialize the SQLite command shell. When it is initialized, by default this SQLite session is using an in-memory database, not a file on disk, and so all changes will be lost when the session exits. To use a persistent disk file as the database, enter the ".open ex1.db" command immediately after the terminal window starts up.

The example above causes the database file named "ex1.db" to be opened and used, and created if it does not previously exist. You might want to use a full pathname to ensure that the file is in the directory that you think it is in. Use forward-slashes as the directory separator character. In other words use "c:/work/ex1.db", not "c:\work\ex1.db".

To see all tables in the database you have previously chosen, type the command .tables as it is said in the above link.

If you work in Windows, I think it might be useful to move this sqlite.exe file to same folder with the other Python files. In this way, the Python file writes to and the SQLite shell reads from .db files are in the same path.

Use .da to see all databases - one is 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'

---

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);
