Type mismatch issue where column contains some alpha numeric entries but Starfish believes the data is numeric.
If a column of data contains numeric data for the first few rows and then later contains alphanumeric data Starfish will expect numeric data from every row in the data and will then fail to parse the alphanumeric data. Because by default the Microsoft Jet driver that is used for this functionality only scans the first 16 rows, it tries to make a ‘guess’ based on that data for each column type. This is only a problem is the data changes from numeric to alphanumeric partway through the data as thinks the data is all numbers. In registry, navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Jet\4.0\Engines\Text Find the MaxScanRows key, and change the value to ‘0’. Restart Starfish. It may also be necessary to perform an IISRESET.
