How to avoid last line(ie repeating last line)

Question

I wrote a procedure for writing DB table to flat file.
but the last line is repeating ie printing twice.
     OPEN curr_v FOR str_all_cols_sel;          
LOOP FETCH curr_v INTO l_columnValue;
          utl_file.put_line(l_output,l_columnValue);
EXIT WHEN curr_v%NOTFOUND;
END LOOP; -- curr_v
Any help?

Answer 1

If you reached the last record, it gets printed. Then it fetches once more, but no data is found. However you first print and then exit. That's why the last line gets printed twice.
The code should be:
OPEN curr_v FOR str_all_cols_sel;
LOOP
FETCH curr_v INTO l_columnValue;
EXIT WHEN curr_v%NOTFOUND;
utl_file.put_line(l_output,l_columnValue);
END LOOP; -- curr_v
