Utl_file + query

Question

Hi guys.
I am really newbie in procedures.
I am trying to implement a procedure, using utl_dir :
create or replace procedure UTL_FILE_EXAMPLE is
FILE_HANDLE utl_file.file_type;
COL1 varchar2;
RETRIEVED_BUFFER varchar2(100);
DIR_NAME varchar2(40) := 'UTF_DIR';
FILE_NAME varchar2(40) := 'myfile.txt';
begin
FILE_HANDLE := utl_file.fopen(DIR_NAME,FILE_NAME,'W');
utl_file.put_line(FILE_HANDLE, 'auditing and testing');
cursor CUR_EMISOR is
SELECT username,
extended_timestamp,
owner,
obj_name,
action_name,
sql_text
FROM dba_audit_trail
ORDER BY timestamp;
utl_file.putf (
FILE_HANDLE, CUR_EMISOR
utl_file.fclose(FILE_HANDLE);
file_handle := utl_file.fopen(DIR_NAME,FILE_NAME,'R');
utl_file.get_line (FILE_HANDLE, RETRIEVED_BUFFER);
dbms_output.put_line(RETRIEVED_BUFFER);
utl_file.fclose(FILE_HANDLE);
end;
I am trying to get the results of the query and put it on a .txt file.
Could anybody gimme a hint ?
Thanks!

Hello guys.
I've Tried to follow user11181920´s hint
create or replace procedure UTL_FILE_EXAMPLE is
FILE_HANDLE utl_file.file_type;
COL1 varchar2(10);
RETRIEVED_BUFFER varchar2(100);
DIR_NAME varchar2(40) := 'UTF_DIR';
FILE_NAME varchar2(40) := 'myfile.txt';
begin
FILE_HANDLE := utl_file.fopen(DIR_NAME,FILE_NAME,'W');
FOR C in (
SELECT username,extended_timestamp,owner,obj_name,action_name,sql_text FROM dba_audit_trail
ORDER BY timestamp)
LOOP
utl_file.put_line(FILE_HANDLE,C.username||','||C.extended_timestamp||','||C.owner);
END LOOP;
utl_file.fclose(FILE_HANDLE);
end;
I had some errors:
At line 11: PL/SQL: ORA-00942: table or view does not exist
At Line 11: PL/SQL: sql statement ignored
At line 15: PLS-00364: loop index variable 'C' use in invalid
At line 15: PL/SQL: sql statement ignored
Ps.: Normally i can do this select, i have access on the table, the table has this columns mentioned on the query.
Thanks.
