com.tableausoftware.nativeapi.dll.DataSourceException: [Teradata][ODBC Teradata Driver][Teradata Database] Syntax error: expected something between the 'AND' keyword and the 'HOUR' keyword.
Unable to connect to the server "tdps.ukroi.tesco.org". Check that the server is running and that you have access privileges to the requested database.
Are you using any initial SQL on that extract ?
