MongoDB Conditional Operators

MongoDB conditional operators are a set of special operators used to perform conditional checks, including ifNull, cond, and switch, which can be used to perform conditional branching and data conversion operations in aggregation queries. This page summarizes the conditional operators in MongoDB.

  1. $cond

    The $cond operator in MongoDB is a conditional expression operator used to evaluate and process data.

  2. $ifNull

    The $ifNull operator is used to look for a specified field in a document.

  3. $switch

    The $switch operator is one of the conditional statement operators in MongoDB, which can execute multiple different operations based on the given expression value, similar to the switch statement in programming languages.
