 // Params:
 // 1. query (filter) if you only want to remove this field from some records. {} will select any.
 // 2. $unset the field(s) that you want to remove. Here I've set them to null but the value doesn't matter as it's ignored.
 // 3. multi must be set to true otherwise it will only operate on the first record that it finds.
 // 
 // Run this command in the MongoDB shell

 db.<collectionName>.update( {}, {$unset: {<fieldName1>: null, <fieldName2>: null}}, {multi: true});
