Java/MongoDB query by date

Question

I stored a value as a java.util.Date() in my collection, but when I query to get values between two specific dates, I end up getting values outside of the range. Here\'s my

Answer 1

Search Date with specific format following steps are that this also work in mongo 3.0

SimpleDateFormat simpleDateFormat = new SimpleDateFormat ("yyyy.MM.dd");

First convert your date in your specific format, you can use any format and parse your date with above format and then pass in query.

String date ="2014.01.02"; 
String data1 ="2014.01.10";
Date startDate = simpleDateFormat.parse(date);  
Date endDate = simpleDateFormat.parse(date1);

BasicDBObject query = new BasicDBObject("fieldName",
   new BasicDBObject("$gte",startDate).append("$lt",endDate ));

So base on your requirement you can search date by giving argument in BasicDBobject.

Answer 2

What you're doing is querying only with {$lte: toDate} losing $gte operator in the key overwrite. What you want is:

query.put("dateAdded", BasicDBObjectBuilder.start("$gte", fromDate).add("$lte", toDate).get());

Answer 3

I approach the query like this

new Document("datetime",Document.parse(
    "{$gte: ISODate('" + new SimpleDateFormat("yyyy-MM-dd").format(fromDate) + "'), 
     $lte: ISODate('" + new SimpleDateFormat("yyyy-MM-dd").format(endDate) + "')}"
))

Answer 4

You can do

    import org.bson.conversions.Bson;
    import static com.mongodb.client.model.Filters.*;
    import java.text.SimpleDateFormat;

    DateFormat format = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
    Bson filter = Filters.and(gte("date_field", format.parse("2018-10-01")),
                            lt("date_field", format.parse("2019-10-01")))

Answer 5

If you are using MongoTemplate of Spring-Data Mongodb, you can do the same in following way:-

public List<Link> getLinksBetweenDate(Date startDate, Date endDate) {
            Query query = new Query().addCriteria(Criteria.where("updatedOn").gt(startDate).lte(endDate));
            return mongoTemplate.find(query, Link.class);
        }

Answer 6

Using mongo client 3.0

DateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", Locale.ENGLISH);
Bson filter = new Document("$gte", format.parse("2015-05-01T00:00:00Z")).append("$lt", format.parse("2015-05-02T00:00:00Z"));
long count = db.getCollection("colection").count(new Document("field",filter) );
