Oracle – Remove Column Header into the Output Text file

columnheaderoracleoracle-sqldeveloperspoolsqlplus

I want to create a flat file (text file) of my query from Oracle SQL Developer.

I have successfully created the text file using SPOOL, thru a script text file, but i want to remove the header of each column into my output.

I am getting this output:

Header000001 Header000002
------------ ------------
Adetail1     Bdetail1
Adetail2     Bdetail2
Adetail3     Bdetail3

But, I want to get this output:

Adetail1Bdetail1
Adetail2Bdetail2
Adetail3Bdetail3

I already tried the command "set heading off", but a message says:

"SQLPLUS COMMAND Skipped: set heading off".

These are the inputs I've issued:

spool on; 
spool C:\SQLFiles\PSB_ATMLKP.txt; 
set newpage 0; 
set echo off; 
set feedback off; 
set heading off; 

select terminal_number, terminal_name from terminal_table; 

spool off;

SQLPLUS COMMAND Skipped: set heading off

That message is most likely because you are not executing it through SQL*Plus, but some GUI based tool. You are using SQLPlus command in SQL Developer. Not all SQL*Plus commands are guaranteed to work with SQL Developer.

I would suggest you execute the script in SQLPlus and you would see no issues.

You need:

SET HEADING OFF

This will not include the column headers in the output.

Alternatively, you could also do this:

SET PAGESIZE 0

Using SQL Developer Version 3.2.20.10:

spool ON
spool D:\test.txt
SET heading OFF
SELECT ename FROM emp;
spool off

enter image description here

Spool file got created with no issues:

> set heading OFF
> SELECT ename FROM emp
