Splunk DB Connect and MSSQL View

I am using DB Connect V2 to query tables in MSSQL 2014 and no problem. Then I created a DB Input pointing to the same DB but a simple View rather than a table and during the Input setup query preview step the SQL query runs for at least 5mins and no response. This is a simple <1sec query, so I created a table with the same data as the view and that worked. Is there a limitation on this app that does not allow for querying views? In the "Advanced query" option I played with the syntax to validate that SQL server was retrieving error messages.
