Aggregation Expression - $and

Function Build

Build $and with the And function from the aggregation package.

// bson.D{bson.E{Key:"valid", Value:bson.D{bson.E{Key:"$and", Value:[]interface {}{"$isActive", "$isVerified"}}}}}
result := aggregation.And("valid", "$isActive", "$isVerified")

Method Build (Builder)

Build $and with the And method from aggregation.NewBuilder().

// bson.D{bson.E{Key:"valid", Value:bson.D{bson.E{Key:"$and", Value:[]interface {}{"$isActive", "$isVerified"}}}}}
result := aggregation.NewBuilder().
    And("valid", "$isActive", "$isVerified").
    Build()

Build Without Key

When an expression needs to be passed as an argument to another expression, use a WithoutKey variant to build an expression fragment without an output field name.

AndWithoutKey

Function build:

// bson.D{bson.E{Key:"$and", Value:[]any{"$isActive", "$isVerified"}}}
expr := aggregation.AndWithoutKey("$isActive", "$isVerified")

Method build (Builder):

// bson.D{bson.E{Key:"$and", Value:[]any{"$isActive", "$isVerified"}}}
expr := aggregation.NewBuilder().
    AndWithoutKey("$isActive", "$isVerified").
    Build()
