$lte
¶ Syntax:
{ field: { $lte: value} }
$lte
selects the documents where the value of thefield
is less than or equal to (i.e.<=
) the specifiedvalue
.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 theqty
field value is less than or equal to20
.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 theprice
field value in the documents that contain the embedded documentcarrier
whosefee
field value is less than or equal to5
.
