  • CPython >= 3.6 recommended (>= 3.4 will work, probably)

• rqlite Server

Example

The following code creates a connection and executes some statements:

import aiorqlite

@aiorqlite.arun
async def main():
        # Connect to the database
        async with aiorqlite.connect(':memory:') as db:
                async with db.cursor() as cursor:
                        await cursor.execute('CREATE TABLE foo (id integer not null primary key, name text)')
                        await cursor.executemany('INSERT INTO foo(name) VALUES(?)', seq_of_parameters=(('a',), ('b',)))

                async with db.cursor() as cursor:
                        # Read a single record with qmark parameter style
                        sql = "SELECT `id`, `name` FROM `foo` WHERE `name`=?"
                        await cursor.execute(sql, ('a',))
                        result = await cursor.fetchone()
                        print(result)
                        # Read a single record with named parameter style
                        sql = "SELECT `id`, `name` FROM `foo` WHERE `name`=:name"
                        await cursor.execute(sql, {'name': 'b'})
                        result = await cursor.fetchone()
                        print(result)

main()

This example will print:

{'id': 1, 'name': 'a'}
{'id': 2, 'name': 'b'}

Paramstyle

Only qmark and named paramstyles (as defined in PEP 249) are supported.

Limitations

Transactions are not supported.
