$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:
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:
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.
