Golang mongo-go-driver Beta 1 , using greater than operator

I have been trying to get records greater than an _id provided The code is below

filter = bson.M{"_id": bson.M{"$gt": "5c1760b4bd421c09e0f3140c"}}
cur, err := collection.Find(ctx, filter, &options)

But iam always getting null values. I think i need to convert that id to object id But iam not sure how to do it in latest release There is a bson.TypeObjectID shown in predictions . Can someone please provide some details to do this.? Thanks

Solution

  • You need to compare ObjectID to ObjectID. What you are doing is comparing an ObjectID to a string.

    objectID, _ := primitive.ObjectIDFromHex("5c1760b4bd421c09e0f3140c")
filter = bson.M{"_id": bson.M{"$gt": objectID}}
cur, err := collection.Find(ctx, filter, &options)
