How do I spool to a CSV formatted file using SQLPLUS?

Solution 1:

You could also use the following, although it does introduce spaces between fields.

set colsep ,     -- separate columns with a comma
set pagesize 0   -- No header rows
set trimspool on -- remove trailing blanks
set headsep off  -- this may or may not be useful...depends on your headings.
set linesize X   -- X should be the sum of the column widths
set numw X       -- X should be the length you want for numbers (avoid scientific notation on IDs)

spool myfile.csv

select table_name, tablespace_name 
  from all_tables
 where owner = 'SYS'
   and tablespace_name is not null;

Output will be like:

    TABLE_PRIVILEGE_MAP           ,SYSTEM                        
    SYSTEM_PRIVILEGE_MAP          ,SYSTEM                        
    STMT_AUDIT_OPTION_MAP         ,SYSTEM                        
    DUAL                          ,SYSTEM 
...

This would be a lot less tedious than typing out all of the fields and concatenating them with the commas. You could follow up with a simple sed script to remove whitespace that appears before a comma, if you wanted.

Something like this might work...(my sed skills are very rusty, so this will likely need work)

sed 's/\s+,/,/' myfile.csv 

Solution 2:

If you are using 12.2, you can simply say

set markup csv on
spool myfile.csv

Solution 3:

I use this command for scripts which extracts data for dimensional tables (DW). So, I use the following syntax:

set colsep '|'
set echo off
set feedback off
set linesize 1000
set pagesize 0
set sqlprompt ''
set trimspool on
set headsep off

spool output.dat

select '|', <table>.*, '|'
  from <table>
where <conditions>

spool off

And works. I don't use sed for format the output file.

Solution 4:

I see a similar problem...

I need to spool CSV file from SQLPLUS, but the output has 250 columns.

What I did to avoid annoying SQLPLUS output formatting:

set linesize 9999
set pagesize 50000
spool myfile.csv
select x
from
(
select col1||';'||col2||';'||col3||';'||col4||';'||col5||';'||col6||';'||col7||';'||col8||';'||col9||';'||col10||';'||col11||';'||col12||';'||col13||';'||col14||';'||col15||';'||col16||';'||col17||';'||col18||';'||col19||';'||col20||';'||col21||';'||col22||';'||col23||';'||col24||';'||col25||';'||col26||';'||col27||';'||col28||';'||col29||';'||col30 as x
from (  
      ...  here is the "core" select
     )
);
spool off

the problem is you will lose column header names...

you can add this:

set heading off
spool myfile.csv
select col1_name||';'||col2_name||';'||col3_name||';'||col4_name||';'||col5_name||';'||col6_name||';'||col7_name||';'||col8_name||';'||col9_name||';'||col10_name||';'||col11_name||';'||col12_name||';'||col13_name||';'||col14_name||';'||col15_name||';'||col16_name||';'||col17_name||';'||col18_name||';'||col19_name||';'||col20_name||';'||col21_name||';'||col22_name||';'||col23_name||';'||col24_name||';'||col25_name||';'||col26_name||';'||col27_name||';'||col28_name||';'||col29_name||';'||col30_name from dual;

select x
from
(
select col1||';'||col2||';'||col3||';'||col4||';'||col5||';'||col6||';'||col7||';'||col8||';'||col9||';'||col10||';'||col11||';'||col12||';'||col13||';'||col14||';'||col15||';'||col16||';'||col17||';'||col18||';'||col19||';'||col20||';'||col21||';'||col22||';'||col23||';'||col24||';'||col25||';'||col26||';'||col27||';'||col28||';'||col29||';'||col30 as x
from (  
      ...  here is the "core" select
     )
);
spool off

I know it`s kinda hardcore, but it works for me...
