Python Sqlite3 Get Sqlite Connection path

Question

Given an sqlite3 connection object, how can retrieve the file path to the sqlite3 file?

Answer 1

The Python connection object doesn't store this information.

You could store the path before you open the connection:

path = '/path/to/database/file.db'
conn = sqlite3.connect(path)

or you can ask the database itself what connections it has, using the database_list pragma:

for id_, name, filename in conn.execute('PRAGMA database_list'):
    if name == 'main' and filename is not None:
        path = filename
        break

If you used a connection URI (connecting with the sqlite3.connect() parameter uri=True), the filename will not include the URI parameters or the file:// prefix.
