使用 $and 条件创建过滤器，SQL 到 golang 过滤器转换器？

Question

I have currently a working filter for.DeleteMany. It deletes all entries where _id is in the given array vids :

filter := bson.D{{Key: "_id", Value: bson.D{{Key: "$in", Value: vids}}}}
res, err := DB.Collection("data").DeleteMany(context.TODO(), filter)

Now I want to enhance the filter and add some $and condition to only delete entries where _id is in the given array vids and(!) the value of providerid is 1234 .

Sadly I'm stuck on how to do that in go. For me it is extremely hard to read and write such filters. Especially with all that bson.D, bson.M and []bson.D and the many curly brackets etc.

In SQL I would write DELETE FROM data WHERE _id IN( {list} ) AND providerid=1234;

Is there any SQL to golang mongodb filter converter?

Answer 1

Try

filter := bson.D{
    { "$and", []interface{}{
        bson.D{{ Key: "_id", Value: bson.D{{ Key: "$in", Value: vids }}}},
        bson.D{{ "providerid", 123}},
    }},
}

As per @VolkerSchmid comment

filter := bson.D{ { Key: "$and", Value: []interface{}{ bson.D{{ Key: "_id", Value: bson.D{{ Key: "$in", Value: vids }}}}, bson.D{{ Key: "providerid", Value: 123}}, }}, }
