问题
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
回答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.

set echo off
spool c:\test.csv
select /*csv*/ username, user_id, created from all_users;
spool off;
回答3:
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
回答4:
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.
回答5:
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;
