title: SQL Server Import Wizard treats NULL as literal string 'NULL'
body: <p>When I attempt to import a <code>.csv</code> comma-delimited flat file into a <code>Microsoft SQL server 2008R2 64-bit instance</code>, for <code>string</code> columns a <code>NULL</code> in the original data becomes a literal string <code>"NULL"</code> and in a <code>numeric</code> column I receive an import error. Can anyone please help??? </p>
