# A Python DB API 2.0 for Druid #

This module allows accessing Druid via its [experimental SQL API](http://druid.io/docs/latest/querying/sql.html).

## Usage ##

Using the DB API:

```python

from druiddb import connect

conn = connect(host='localhost', port=8082, path='/druid/v2/sql/', scheme='http')

curs = conn.cursor()

curs.execute("""

    SELECT place,

           CAST(REGEXP_EXTRACT(place, '(.*),', 1) AS FLOAT) AS lat,

           CAST(REGEXP_EXTRACT(place, ',(.*)', 1) AS FLOAT) AS lon

      FROM places

     LIMIT 10

""")

for row in curs:

    print(row)

```

        

Using SQLAlchemy:

```python

from sqlalchemy import *

from sqlalchemy.engine import create_engine

from sqlalchemy.schema import *

engine = create_engine('druid://localhost:8082/druid/v2/sql/')  # uses HTTP by default :(

# engine = create_engine('druid+http://localhost:8082/druid/v2/sql/')

# engine = create_engine('druid+https://localhost:8082/druid/v2/sql/')

places = Table('places', MetaData(bind=engine), autoload=True)

print(select([func.count('*')], from_obj=places).scalar())

```

Using the REPL:

```bash

$ druiddb http://localhost:8082/druid/v2/sql/

> SELECT COUNT(*) AS cnt FROM places

  cnt

-----

12345

```
