Postgresql: Query Between time range using jsonb field -


i have table 2 fields:

id(serial), data(jsonb)

and data have records datetime field stored unix timestamps:

{"device":132,"datetime": 1434166552,...}

i'm trying query between ranges:

select * trips data->>'datetime' between     extract(epoch date '2014-04-01') ,     extract(epoch date '2014-04-15' + interval '1 day')     , id = 123

message

error:  operator not exist: text >= double precision line 3: data->>'datetime' between

something i'm doing wrong, please cloud me? thanks.

the ->> operator returns json object field text (see here). need cast :

select * trips (data->>'datetime')::int    between extract(epoch date '2014-04-01')        , extract(epoch date '2014-04-15' + interval '1 day')   , id = 123
