MongoDB - Script to Delete all collection with exclusion

Semplice script per eliminare tutte le collection di un db ad esclusione di una lista di collection.

	function deleteAllCollection(dbName,excludeCollection){
	var dbOne = db.getSisterDB(dbName);
	for(var colName in dbOne.getCollectionNames()){
	var collectionName = dbOne.getCollectionNames()[colName];
	if(!collectionName || collectionName == "")
	continue;
	if(excludeCollection.indexOf(collectionName) > -1)
	continue;
	dbOne[collectionName].drop();
	};
	};
	deleteAllCollection("<dbName>",["<exclude_col_name_1>","<exclude_col_name_2>","<exclude_col_name_N>"]]);
	//run with
	// mongo --host <host_name> --port <port_name> DropCollectionInDB.js
