How to update date field in mongo console?

Question

For example I want to update all records to \'2012-01-01\' ( \"time\" : ISODate(\"2011-12-31T13:52:40Z\") ).

db.test.update( { time : \'2012-01-01\' }, false,          


        

Answer 1

You can do this in the old-school way by creating ISO date

  db.test.update({_id : 1}, {
      $set : {
         "time" : new ISODate("your current date")
      }
  });

But note that with new Mongo 2.6 you will be able to update date to a current date really easy with $currentDate.

db.test.update( { _id: 1 }, {
  $currentDate: {
      time: true,
  },
})
