Contents
Requirements
- Python -- one of the following:
- 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.
