[Attribute] metaData [Restrictions] Optional [Meaning] 
If you specify metaData to be returned in a query request message, QuickBooks will return a retCount containing the approximate count of query objects to be returned. You can specify that the count of query objects is to be returned with the returned objects, or you can specify that only a count and no data is returned. (The default is that no count is returned.) If you don’t want a query to return a count, either don’t use this feature, or specify the value NoMetaData. If you want only a count, specify the value MetaDataOnly. If you want data and a count, specify MetaDataAndResponseData.
