$lte¶

$lte¶

Syntax: { field: { $lte: value} }

$lte selects the documents where the value of the field is less than or equal to (i.e. <=) the specified value.

For most data types, comparison operators only perform comparisons on fields where the BSON type matches the query value’s type. MongoDB supports limited cross-BSON comparison through Type Bracketing.

Consider the following example:

copy

db.inventory.find( { qty: { $lte: 20 } } )

This query will select all documents in the inventory collection where the qty field value is less than or equal to 20.

Consider the following example which uses the $lt operator with a field from an embedded document:

copy

db.inventory.update( { "carrier.fee": { $lte: 5 } }, { $set: { price: 9.99 } } )

This update() operation will set the price field value in the documents that contain the embedded document carrier whose fee field value is less than or equal to 5.
