Seeking simple example pl/sql to create text file from table data

Question

hello,
I am hoping someone can provide very simple example of creating a file on my local harddrive using a pl/sql program. The basic steps are as follows:
First, I store some text in a varchar2 variable like this:
1. select sometext into otextvar from mytable where recordid = 1;
Second, I want this text to become a file in my data directory:
2. c:\data\sometext.txt
The second step is where I need help.
Any suggestions are greatly appreciated.

Use this function
It will create for you a file in your /home/oracle directory with sysdate name and will insert all table names in it
CREATE OR REPLACE PROCEDURE my_proc AS
CURSOR cursor1 IS
SELECT table_name from all_tables;
CURSOR cursor2 IS
SELECT sysdate from dual;
rec1 cursor1%ROWTYPE;
rec2 cursor2%ROWTYPE;
created_file_name VARCHAR2(100);
file_name utl_file.file_type;
BEGIN
OPEN cursor2;
LOOP
FETCH cursor2 INTO rec2;
EXIT WHEN cursor2%NOTFOUND;
created_file_name:=rec2.sysdate;
file_name := utl_file.fopen('/home/oracle', created_file_name,'W');
OPEN cursor1;
LOOP
FETCH cursor1 INTO rec1;
EXIT WHEN cursor1%NOTFOUND;
utl_file.putf(file_name, '%s\n',rec1.TABLE_NAME);
END LOOP;
utl_file.fclose(file_name);
END LOOP;
END my_proc;
SQL>exec my_proc;
