MongoDB Query Operator $lte - Complete Tutorial

Understanding the $lte Operator

The $lte operator stands for 'less than or equal to'. It is used in MongoDB queries to match documents where the value of a specified field is less than or equal to the provided value.

This operator is part of MongoDB's comparison query operators, which allow you to compare field values against specified criteria.

• Syntax: { field: { $lte: value } }
• Matches documents where field ≤ value
• Works with numbers, dates, and strings

Using $lte in Queries

To use $lte, include it in the query document specifying the field and the maximum value allowed.

For example, to find all documents where the age is less than or equal to 30, you would write a query using $lte.

Combining $lte with Other Operators

MongoDB allows combining $lte with other operators like $gte to specify ranges.

This is useful for filtering documents where a field's value falls within a specific range.

• Use $gte and $lte together for inclusive range queries
• Combine with $and or $or for complex conditions
