             Summary: JDBC getColumnName may return empty string
                 Key: NIFI-2918
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.1.0
            Reporter: Peter Wicks
            Assignee: Peter Wicks

The SAP Hana JDBC Driver returns an empty string for getColumnName if the 
column name in the SELECT statement was aliased.

Instead you have to call getColumnLabel on the ResultSetMetaData.

SAP as a company feels this is per the JDBC spec, so they are not going to 
change it.
