Remove in momgodb using java not giving proper result. Am i missing something? My database is as below. enter image description here

My code for removeing records where index = "7" is as,

BasicDBObject whereQuery = new BasicDBObject("nodes.index", new BasicDBObject("$eq", "7"));
node_info.remove(whereQuery);

It's returning all the records and deleting my complete database. What can be probably wrong.?

Instead of remove try $pull method code as below 

BasicDBObject match = new BasicDBObject("_id", object id here);
BasicDBObject update = new BasicDBObject("nodes", new BasicDBObject("index", 7)))
node_info.update(match, new BasicDBObject("$pull", update);

  • Superb. Thank you very much. _id is auto-generated so i used match = node_info.findOne() instead of your query. than works well. – Hitesh Vaghani Apr 13 '15 at 09:12
