How to change the type of a field?

Question

I am trying to change the type of a field from within the mongo shell.

I am doing this...

db.meta.update(
  {\'fields.properties.default\': { $type :         


        

Answer 1

db.coll.find().forEach(function(data) {
    db.coll.update({_id:data._id},{$set:{myfield:parseInt(data.myfield)}});
})
