Note : Not Tested.
DECLARE
V1 VARCHAR2(32767);
F1 UTL_FILE.FILE_TYPE;
cursor c1 is select ename,empno from emp;
r_c1 c1%rowtype;
BEGIN
-- In this example MAX_LINESIZE is less than GET_LINE's length request
-- so the number of bytes returned will be 256 or less if a line terminator is seen.
open c1;
F1 := UTL_FILE.FOPEN('MYDIR','MYFILE','W',256);
loop
fetch c1 into r_c1;
v1:= r_c1.ename||''||To_char(r_c1.empno);
UTL_FILE.PUT_LINE (F1, v1,TRUE);
v1:= null;
Exit when c1%not found;
end loop;
UTL_FILE.FCLOSE(F1);
