Compare 2 dates in mongo find method

Question

I have mongo documents containing a last_active date and a created date. I would like to search for all documents where the day of last_active is not equal

Answer 1

You can use a function within your query:

db.mycollection.find({
  $where: function() {
    return this.created.getDate() !== this.last_active.getDate();
  }
})
