Hi Anju,
You can format Col Output before sending it to file. Here is one Sample I just
tried on 10g. Let us know if you are getting stuck somewhere. One point to
highlight: the files are generated on database server, security (if you have
one) may Object to this. In our env. Interfaces are to be dealt with on
Mid-tier.
AM01:AMAR> create or replace directory tmp as '/tmp/';
Directory created.
create or replace procedure utl_file_io is
l_fil utl_file.file_type;
l_buf varchar2(200);
begin
l_fil := utl_file.fopen('TMP', 'amar_test.t', 'W');
utl_file.put_line(l_fil, 'This is a sample text file.');
utl_file.put_line(l_fil, 'Generated from Oracle utl_file package.');
utl_file.put_line(l_fil, 'Below is the content of am1010 table.');
for rec in (select col1, col2 from am1000) loop
utl_file.put_line(l_fil, rpad(rec.col1, 15, ' ') || rec.col2);
end loop;
utl_file.put_line(l_fil, 'End of File');
utl_file.fclose(l_fil);
l_fil := utl_file.fopen('TMP', 'amar_test.t', 'R');
loop
utl_file.get_line(l_fil, l_buf);
dbms_output.put_line(l_buf);
end loop;
exception
when no_data_found then
utl_file.fclose(l_fil);
end;
/
AM01:AMAR> exec utl_file_io

Subject: Writing text file from PL/SQL block
hi list,
I have a strange but interesting problem. I have three tables with below
structure , I need to generate a text file using a PL/SQL block on the basis
of below criteria:
Table1 structure
****************
dealerid number;name varchar2(100);age number(3);sex char(1);
table2 structure
*******************
feed_id number(10);feed_name varchar(20);feed_format clob;
table3 structure
******************
feed_id number(10);column_name varchar2(100); -- to store the column name of
table1
column_position number(2); -- to store at what position column of table1
should be written
application_id number(4); -- to store what application it is
scenario1
************
i have to generate a text file from PL/SQL block wherein table1 column data
should be written based on the position mentioned in table3. for example if
dealerid is in 3 position,name is in 1 and age is in 2 position then my text
file should contain data something like :
name,age,position
Scenario2
************
if table3 doesnt contain any record for any column of table1 then that
column should not be written.
I know it can only be done using UTL_FILE package but dont know how to
achieve it? I would really be obliged if anyone can provide with a sample
block to achive this to me.
Please
