Column heading is not coming while generating a .csv file from .sql file

Question

Hi all,
Now since I am able to generate a .csv file by executing my .sql file, the column heading is missing in that. Please advise. I have used the following parameters in my query:
set linesize 1000
set colsep ','
set echo off
set feedback off
set pagesize 0
set trimspool on
spool /path/file.csv
select ...... from .... where .....;
spool off
exit

Answer 1

set pagesize 0 <-- your problem
you must set it into a high value (max value 50000)
see:
SQL> select * from dual;
D
X
SQL> set pagesize 0
SQL> select * from dual;
X
SQL> set pagesize 50000
SQL> select * from dual;
D
X
