2- db.copyDatabase('nexgtv_16','nexgtv_bcup_9aug','172.31.22.235');

3-  Create replicate table in mongodb

db.ASSETS.aggregate([{"$match":{}},{"$out":"Assets_5August"}])

4. //group by record

db.ASSETS.aggregate(
   {$group : { '_id' : "$channel_name",'charge_code':{'$first':'$charge_code'},'platform':{'$first':'$platform'}}}
)


 db.KEYWORDS.aggregate(
 [
 {"$group":
 {"_id":{"title":"$title"},
 "uniqueIds":{"$addToSet":"$_id"},
 "count":{"$sum":1}}},
 {"$match":{"count":{"$gte":2}}},
 {"$sort":{"count":-1}}
 ]).pretty();


 db.KEYWORDS.aggregate(

 {"$group":
 {"_id":{"title":"$title"},
 "uniqueIds":{"$addToSet":"$_id"},
 }}


 ).pretty();

Q1:- update query command line using mongo db:-

db.ASSETS.update({categories:{$in:['CTG513','CTG514']}},{$set:
{content_id:"5682cd15cc95b319a65da89b"}},{multi:true})



Q2:- 


db.ASSETS.aggregate([{"$match":{"plateform":{"$in":["mobile_app","all"]},"status":"1","catlogue":{"$in":["565c8c878c86ba151d29b689"]},
