Use db2_fetch_row to iterate through a result set, or to point to a specific row in a result set if you requested a scrollable cursor.
To retrieve individual fields from the result set, call the db2_result function.
Rather than calling db2_fetch_row and db2_result, most applications will call one of db2_fetch_assoc, db2_fetch_both, or db2_fetch_array to advance the result set pointer and return a complete row as an array.
A valid stmt resource.
With scrollable cursors, you can request a specific row number in the result set. Row numbering is 1-indexed.
Returns true if the requested row exists in the result set. Returns false if the requested row does not exist in the result set.
