       long count
           number of rows to fetch for FETCH_FORWARD or FETCH_BACKWARD; absolute row number to fetch for
           FETCH_ABSOLUTE; or relative row number to fetch for FETCH_RELATIVE

RETURN VALUE

NOTES

       See the SQL FETCH(7) command for details of the interpretation of the direction and count parameters.

       Direction values other than FETCH_FORWARD may fail if the cursor's plan was not created with the
       CURSOR_OPT_SCROLL option.
