Description
Bug report
Bug description:
root issue is here ( discussed w\ @zzzeek ): https://github.com/sqlalchemy/sqlalchemy/discussions/12767
An explicit emit of the autocommit attribute (=False) makes PRAGMA command not work. Example of the code:
engine = create_async_engine(
config.SQLITE_URL,
echo=True,
connect_args={"autocommit": False},
poolclass=NullPool
)
@event.listens_for(engine.sync_engine, "connect", named=True)
def enable_foreign_keys(dbapi_connection: AsyncAdapt_aiosqlite_connection, connection_record):
cursor = dbapi_connection.cursor()
cursor.execute("PRAGMA foreign_keys=ON")
cursor.execute("PRAGMA foreign_keys")
result = cursor.fetchone()
print(f"Foreign keys pragma value: {result}")
cursor.close()
