How to update a single field in a MongoDB collection for all documents matching a specific criteria
// FROM: http://www.mongodb.org/display/DOCS/Updating#Updating-update%28%29
//
// db.collection.update( criteria, objNew, upsert, multi )
// criteria - query which selects the record to update;
// objNew - updated object or $ operators (e.g., $inc) which manipulate the object
// upsert - if this should be an "upsert"; that is, if the record does not exist, insert it
// multi - if all documents matching criteria should be updated
//
// SQL VERSION:
// UPDATE myTable SET dateField = '2011-01-01' WHERE condField = 'condValue'
db.myCollection.update({condField: 'condValue'}, { $set: { dateField: new Date(2011, 0, 1)}}, false, true);
