SQL API example

from cartoasync import Auth, SQLClient

auth = Auth(username='username', api_key='api_key')
sql_client = SQLClient(auth)
result = await sql_client.send('SELECT 1 AS one;')

print(result)
>>> {
>>>   "rows": [
>>>     {
>>>       "one": 1
>>>     }
>>>   ],
>>>   "time": 0.002,
>>>   "fields": {
>>>     "one": {
>>>       "type": "number"
>>>     }
>>>   },
>>>   "total_rows": 1
>>> }

SQL API example, step by step

1. Instantiate an Auth object:

1.1. CARTO cloud:

auth = Auth(username='username', api_key='api_key')

1.2. CARTO OnPremises or cloud organization with an implict user:

auth = Auth(base_url='https://myapp.com/user/username/', api_key='api_key')

1.3. CARTO OnPremises or cloud organization without an implicit user:

auth = Auth(base_url='https://myapp.com/', username='username', api_key='api_key')

1.4. SSL:

The Auth constructor has and ssl attribute. You can use it for handle to the library a Python's SSL context, or set it to False for relaxing certification checks. More info on AIOHTTP doc.

2. Instantiate the SQLClient and send queries:

2.1. SQLClient's own AIOHTTP session:

sql_client = SQLClient(auth)
result = await sql_client.send('SELECT 1 AS one;')

2.2. External AIOHTTP session you need to care until the end of its days:

import aiohttp

sql_client = SQLClient(auth)
result = await sql_client.send('SELECT 1 AS one;', aiohttp.ClientSession())
