What is Query Modifications?

Mongo DB gives inquiry modifiers, for example, the 'cutoff' and 'Orders' condition to give greater adaptability while executing questions. We will investigate the accompanying question modifiers

MongoDB Limit Query Results

This modifier is utilized to restrict the quantity of reports which are returned in the outcome set for a question. The accompanying model demonstrates the way that this should be possible. db. Employee. find().limit(2).for Each(printjson);The above code takes the find capability which returns each of the reports in the assortment however at that point utilizes the limit statement to restrict the quantity of archives being gotten back to only 2.Assuming the order is executed effectively, the accompanying Output will be shown The result plainly shows that since there is a cutoff modifier, so at most only 2 records are returned as a component of the outcome set in light of the Object Id in climbing request.

MongoDB Sort by Descending Order

One can determine the request for reports to be returned in view of rising or dropping request of any critical in the assortment. The accompanying model demonstrates the way that this should be possible. db. Employee. find().sort({Employeeid:- 1}). for Each (printjson)The above code takes the sort capability which returns each of the reports in the assortment however at that point utilizes the modifier to change the request in which the records are returned. Here the - 1 shows that we need to return the records in view of the diving request of Employee id.

What is Cursor in MongoDB?

When the db. collection. find () capacity is used to search for reports in the grouping, the result returns a pointer to the combination of records returned which is known as a cursor. As per usual, the cursor will be iterated thusly when the result of the request is returned. In any case, one can in like manner explicitly go through the things returned in the cursor separately. Accepting you see the under model, in case we have 3 documents in our combination, the cursor thing will feature the fundamental report and a short time later stress through every one of the records of the variety.

MongoDB cursor

The going with model exhibits the way that this ought to be conceivable.

First we take the result set of the inquiry which finds the Employee's whose id is more noticeable than 2 and dispense it to the JavaScript variable 'my Employee'

Next we use the while circle to rehash through the records which are completely returned as an element of the request.

Finally for each report, we print the nuances of that record in JSON clear game plan.

Accepting the request is executed actually, the going with Output will be shown
