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
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.
