Thank you for the explanation and a sample of creating a cursor.

>As Sergey mentioned using a schema is ideal. If the data comes from a .NET dataset export the dataset with a schema which is the easiest.

>If you don't have a schema you can pre-create the cursor to import to and XMLTOCURSOR() can infer the schema based on the cursor's structure. The following works:

>  <DBKey>1</DBKey>
>  <String>SQLNCLI10</String> 
>  </ConnectionInfo>
></DataBase>
