Here is a list of common evaluation operators in MongoDB.
We are only looking at the basic functionality of these operators as each of these operators can be considered an advanced MongoDB functionality. The MongoDB evaluation operators can evaluate the overall data structure or individual field in a document. Within MongoDB there is a default date property type which stores date. In this example, we retrieve the document with the exact _id value “LS0009100”. must be unique within the population (length greater than 1 character).

The following table contains the common comparison operators. MongoDB comparison operators can be used to compare values in a document. Collections: employees, inventory, payments, promo.(We won’t touch on them all, there are so many.) We’ll use the following dataset with the find() function to demonstrate each operator’s functionality. Now, let’s look at commonly used operators. MongoDB operators can be used with any supported MongoDB command. MongoDB offers the following query operator types: The query operators enhance the functionality of MongoDB by allowing developers to create complex queries to interact with data sets that match their applications. Operators are special symbols or keywords that inform a compiler or an interpreter to carry out mathematical or logical operations. MongoDB offers different types of operators that can be used to interact with the database. Use the right-hand menu to navigate.) What are MongoDB operators? (This article is part of our MongoDB Guide. We’ll explain what they do, then share examples so you can see how they work.
