Solution 1

All it does is check if the returned data consists of a single row, and that the first cell of that row contain a specific value.
If it does, the username exists, if it doesn't it doesn't.

It's not login code, it's registration code most likely - and exactly how it works will depend on the query which filled the DataSet and DataTable(s).

Not necessarily. As I said, "exactly how it works will depend on the query which filled the DataSet and DataTable(s)".
