Question

One of the most common queries I use with mysql is:

select * from database where id in(1,5,3,2,4) order by field(id,1,5,3,2,4)

On a new project I’m using MongoDB, is there a similar query I can use? We use a separate search engine for actual searching and returns a list of ID’s in a specific order.

Answer 1

The equivalent MongoDB query would be:

db.collection.find({id: $in: [1,2,3,4,5]}).sort({id: 1})

But if you wanted to customize the id order beyond pure ascending you’d have to use the aggregation framework.
