SQLFetchScroll versus SQLGetData

[pixieshoes]

As an ODBC novice I need to retrieve more than one row at a time from a database. What are the pro's and con's of the following;

1. Calling SQLFetch with a block cursor and then calling SQLGetData
2. Using SQLFetchScroll

Any replies much appreciated. I've been using the MSDN documentation so far - any there any other recommended sources for learning??

Thanks
