Spool Command: Do not output SQL statement to file - oracle

Question

I am wanting to output a Query to a CSV file and am using the below as a small test;
spool c:\test.csv
select /*csv*/ username, user_id, created from all_users;
spool off;
but the output has the actual select statment as the first line
> select /*csv*/ username user_id created from all_users
USERNAME USER_ID CREATED
REPORT 52 11-Sep-13
WEBFOCUS 51 18-Sep-12
Is there a way to prevent this? I tried SET Heading Off thinking that might do it, but it did not change. I am using SQL Developer an running as script.
Thanks
Bruce

Answer 1

Unfortunately SQL Developer doesn't fully honour the set echo off command that would (appear to) solve this in SQL*Plus.
The only workaround I've found for this is to save what you're doing as a script, e.g. test.sql with:
set echo off
spool c:\test.csv
select /*csv*/ username, user_id, created from all_users;
spool off;
And then from SQL Developer, only have a call to that script:
#test.sql
And run that as a script (F5).
Saving as a script file shouldn't be much of a hardship anyway for anything other than an ad hoc query; and running that with # instead of opening the script and running it directly is only a bit of a pain.
A bit of searching found the same solution on the SQL Developer forum, and the development team suggest it's intentional behaviour to mimic what SQL*Plus does; you need to run a script with # there too in order to hide the query text.

Answer 2

My shell script calls the sql file and executes it. The spool output had the SQL query at the beginning followed by the query result.
This did not resolve my problem:
set echo off
This resolved my problem:
set verify off

Answer 3

Just for anyone who stumbles upon this (after 7+ years) ...
This works for me ... adapt it to your way of invoking sqlplus.
sqlplus -s / as sysdba 2>&1 > /dev/null <<EOF
whenever sqlerror exit sql.sqlcode;
set echo off
set verify off
set feedback off
set term off
set head off
set pages 1000
set lines 200
spool /tmp/whatever.output
### Your_SQL_statement_here ###
example: select sysdate from dual;
example: select * from V\$LOGFILE;
spool off
EOF
-s flag here is the key to not displaying the SQL statements when runing a script.

Answer 4

set echo off
spool c:\test.csv
select /*csv*/ username, user_id, created from all_users;
spool off;

Answer 5

You can directly export the query result with export option in the result grig.
This export has various options to export. I think this will work.

Answer 6

Exec the query in TOAD or SQL DEVELOPER
---select /*csv*/ username, user_id, created from all_users;
Save in .SQL format in "C" drive
--- x.sql
execute command
---- set serveroutput on
spool y.csv
#c:\x.sql
spool off;
