How do I format my oracle queries so the columns don't wrap?

Question

I've tried this, but it doesn't work:

col * format a20000

Do I really have to list every column specifically? That is a huge pain in the arse.

Answer 1

set linesize 3000

set wrap off

set termout off

set pagesize 0 embedded on

set trimspool on

Try with all above values.

Answer 2

set WRAP OFF
set PAGESIZE 0

Try using those settings.

Answer 3

Never mind, figured it out:

set wrap off
set linesize 3000 -- (or to a sufficiently large value to hold your results page)

Which I found by:

show all

And looking for some option that seemed relevant.

Answer 4

I use a generic query I call "dump" (why? I don't know) that looks like this:

SET NEWPAGE NONE
SET PAGESIZE 0
SET SPACE 0
SET LINESIZE 16000
SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET TERMOUT OFF
SET TRIMOUT ON
SET TRIMSPOOL ON
SET COLSEP |

spool &1..txt

@@&1

spool off
exit

I then call SQL*Plus passing the actual SQL script I want to run as an argument:

sqlplus -S user/password@database @dump.sql my_real_query.sql

The result is written to a file

my_real_query.sql.txt
