is there any command return the currently selected db?

[litao cheng]

hi, buddies.

I find the wiki page about the commands, I can't find a command return
the currently selected db.
Is it need to add new command to return this info? corresponding with
the SELECT command.

Best Regards

Generally I have not needed this as the Redis client that sets the
database will know the 'selected database'.
When you first connect to Redis, the initial database is '0', it will
stay at '0' for the duration of the connection until its changed.
This setting is 'per connection', so does not affect any new
connections which will start at the default db of 0.

You can use this example for ugly workaround:

from itertools import count
from redis import Redis, ResponseError

r = Redis()
try:
[r.select(x) and r.set('selected_db', x) for x in count()]
except ResponseError, e:
if not str(e) == 'invalid DB index':
raise e

>>> r.select(5)
'OK'

>>> r.get('selected_db')
5
