API Reference

Connection

aiosqlite.connect(database, *, iter_chunk_size=64, loop=None, **kwargs)

Create and return a connection proxy to the sqlite database.

Parameters:

• database (str | Path) –

• loop (AbstractEventLoop | None) –

• kwargs (Any) –

Return type:

Connection

class aiosqlite.Connection(connector, iter_chunk_size, loop=None)

Bases: Thread

Parameters:

• connector (Callable[[], Connection]) –

• iter_chunk_size (int) –

• loop (AbstractEventLoop | None) –

async __aenter__()

Return type:

Connection

async __aexit__(exc_type, exc_val, exc_tb)

Return type:

None

__await__()

Return type:

Generator[Any, None, Connection]

async backup(target, *, pages=0, progress=None, name='main', sleep=0.25)

Make a backup of the current database to the target database.

Takes either a standard sqlite3 or aiosqlite Connection object as the target.

Parameters:

• target (Connection | Connection) –

• pages (int) –

• progress (Callable[[int, int, int], None] | None) –

• name (str) –

• sleep (float) –

Return type:

None

async close()

Complete queued queries/cursors and close the connection.

Return type:

None

async commit()

Commit the current transaction.

Return type:

None

async create_function(name, num_params, func, deterministic=False)

Create user-defined function that can be later used within SQL statements. Must be run within the same thread that query executions take place so instead of executing directly against the connection, we defer this to run function.

If deterministic is true, the created function is marked as deterministic, which allows SQLite to perform additional optimizations. This flag is supported by SQLite 3.8.3 or higher, NotSupportedError will be raised if used with older versions.

Parameters:

• name (str) –

• num_params (int) –

• func (Callable) –

• deterministic (bool) –

Return type:

None

cursor()

Create an aiosqlite cursor wrapping a sqlite3 cursor object.

Return type:

Cursor

async enable_load_extension(value)

Parameters:

value (bool) –

Return type:

None

execute(sql, parameters=None)

Helper to create a cursor and execute the given query.

Parameters:

execute_fetchall(sql, parameters=None)

Helper to execute a query and return all the data.

Parameters:

• sql (str) –

• parameters (Iterable[Any] | None) –

Return type:

Iterable[Row]

execute_insert(sql, parameters=None)

Helper to insert and get the last_insert_rowid.

Parameters:

• sql (str) –

• parameters (Iterable[Any] | None) –

Return type:

Row | None

executemany(sql, parameters)

Helper to create a cursor and execute the given multiquery.

executescript(sql_script)

Helper to create a cursor and execute a user script.

Parameters:

sql_script (str) –

Cursor

async interrupt()

Interrupt pending queries.

Return type:

None
