API Reference

Connection

aiosqlite.connect(database: Union[str, pathlib.Path], *, iter_chunk_size=64, loop: Optional[asyncio.events.AbstractEventLoop] = None, **kwargs: Any) → aiosqlite.core.Connection

Create and return a connection proxy to the sqlite database.

class aiosqlite.Connection(connector: Callable[], sqlite3.Connection], iter_chunk_size: int, loop: Optional[asyncio.events.AbstractEventLoop] = None)

Bases: threading.Thread

async __aenter__() → aiosqlite.core.Connection

async __aexit__(exc_type, exc_val, exc_tb) → None

__await__() → Generator[Any, None, aiosqlite.core.Connection]

async backup(target: Union[aiosqlite.core.Connection, sqlite3.Connection], *, pages: int = 0, progress: Optional[Callable[[int, int, int], None]] = None, name: str = 'main', sleep: float = 0.25) → None

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

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

async close() → None

Complete queued queries/cursors and close the connection.

async commit() → None

Commit the current transaction.

async create_function(name: str, num_params: int, func: Callable, deterministic: bool = False) → None

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.

In Python 3.8 and above, 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.

cursor() → aiosqlite.cursor.Cursor

Create an aiosqlite cursor wrapping a sqlite3 cursor object.

async enable_load_extension(value: bool) → None

execute(sql: str, parameters: Iterable[Any] = None) → aiosqlite.cursor.Cursor

Helper to create a cursor and execute the given query.

execute_fetchall(sql: str, parameters: Iterable[Any] = None) → Iterable[sqlite3.Row]

Helper to execute a query and return all the data.

execute_insert(sql: str, parameters: Iterable[Any] = None) → Optional[sqlite3.Row]

Helper to insert and get the last_insert_rowid.

executemany(sql: str, parameters: Iterable[Iterable[Any]]) → aiosqlite.cursor.Cursor

Helper to create a cursor and execute the given multiquery.

executescript(sql_script: str) → aiosqlite.cursor.Cursor

Helper to create a cursor and execute a user script.

async interrupt() → None

Interrupt pending queries.

iterdump() → AsyncIterator[str]

Return an async iterator to dump the database in SQL text format.

Example:

async for line in db.iterdump():
    ...

async load_extension(path: str)

async rollback() → None

Roll back the current transaction.

async set_progress_handler(handler: Callable[], Optional[int]], n: int) → None

async set_trace_callback(handler: Callable) → None

Cursors

class aiosqlite.cursor.Cursor(conn: Connection, cursor: sqlite3.Cursor)

Bases: object

async __aenter__()

async __aexit__(exc_type, exc_val, exc_tb)

__aiter__() → AsyncIterator[sqlite3.Row]

The cursor proxy is also an async iterator.

async close() → None

Close the cursor.

async execute(sql: str, parameters: Optional[Iterable[Any]] = None) → aiosqlite.cursor.Cursor

Execute the given query.

async executemany(sql: str, parameters: Iterable[Iterable[Any]]) → aiosqlite.cursor.Cursor

Execute the given multiquery.

async executescript(sql_script: str) → aiosqlite.cursor.Cursor

Execute a user script.

async fetchall() → Iterable[sqlite3.Row]

Fetch all remaining rows.

async fetchmany(size: Optional[int] = None) → Iterable[sqlite3.Row]

Fetch up to cursor.arraysize number of rows.

async fetchone() → Optional[sqlite3.Row]

Fetch a single row.
