Mongodb query on nested array elements

Question

for my new project we started to use mongodb as a document repository. It works great for our requirements but now we need to implement a more advanced query on sub-sub-arr

Answer 1

Since there is no way to tell what driver you use here is a shell solution:

db.foo.find({
    "Asset.Metadata.Platforms.Platform": {
        $elemMatch: {
            "@name": VAR_PLATFORM,
            "PublishingRanges.PublishingRange": {
                $elemMatch: {
                    "@startdate": {$gt: VAR_START},
                    "@enddate": {$lt: VAR_END}
                }
            }
        }
    }  
})

By the way, you could simplify document structure by omitting Platform and PublishingRange and assigning arrays to Platforms an PublishingRanges respectively.
