If you get this error using Microsoft JDBC driver to return records as a ResultSet:
The ResultSet has no current row
ResultSet rs = getResultSetFunction();
rs.next() <-----------
"ResultSet has not current row" does not mean that the resultset has not returned any records. It means that the recordset has not been positioned to the row you want to read from. When you first load the recordset, it's not positioned to any row.
So rs.next() will position the resultset to the first row (i.e. make the first row the current row), so you can read some data from that row.
The result set needs to have a current row to read some data from it.
