Header formatting while spooling a csv file in sqlplus
Solution 1
One easy way to have a csv with just one header is to do
set embedded on
set pagesize 0
set colsep '|'
set echo off
set feedback off
set linesize 1000
set trimspool on
set headsep off
the embedded
is a hidden option but it is important to have JUST one header
Solution 2
This is how I created a header:
set heading off
/* header */
SELECT '"'||PCL_CARRIER_NAME||'","'||SITETX_EQUIP_ID||'","'||SITETX_SITE_STAT||'","'||SITETX_CREATE_DATE||'","'||ADVTX_VEH_WT||'"'
FROM
(
SELECT 'PCL_CARRIER_NAME' AS PCL_CARRIER_NAME
, 'SITETX_EQUIP_ID' AS SITETX_EQUIP_ID
, 'SITETX_SITE_STAT' AS SITETX_SITE_STAT
, 'SITETX_CREATE_DATE' AS SITETX_CREATE_DATE
, 'ADVTX_VEH_WT' AS ADVTX_VEH_WT
FROM DUAL
)
UNION ALL
SELECT '"'||PCL_CARRIER_NAME||'","'||SITETX_EQUIP_ID||'","'||SITETX_SITE_STAT||'","'||SITETX_CREATE_DATE||'","'||ADVTX_VEH_WT||'"'
FROM
(
/* first row */
SELECT to_char(123) AS PCL_CARRIER_NAME
, to_char(sysdate, 'yyyy-mm-dd') AS SITETX_EQUIP_ID
, 'value3' AS SITETX_SITE_STAT
, 'value4' AS SITETX_CREATE_DATE
, 'value5' AS ADVTX_VEH_WT
FROM DUAL
UNION ALL
/* second row */
SELECT to_char(456) AS PCL_CARRIER_NAME
, to_char(sysdate-1, 'yyyy-mm-dd') AS SITETX_EQUIP_ID
, 'value3' AS SITETX_SITE_STAT
, 'value4' AS SITETX_CREATE_DATE
, 'value5' AS ADVTX_VEH_WT
FROM DUAL
) MISSING_HOST_SITE_TX_IDS;
Solution 3
This is how you add a pipe delimited header to SQL statements. Once you spool it out that "something" wont be there
-- this creates the header
select 'header_column1|header_column2|header_column3' as something
From dual
Union all
-- this is where you run the actual sql statement with pipes in it
select
rev.value1 ||'|'||
rev.value2 ||'|'||
'related_Rel' as something
from

I am required to spool a csv from a table in Oracle, using sqlplus. Following is the format required:
"HOST_SITE_TX_ID","SITE_ID","SITETX_TX_ID","SITETX_HELP_ID" "664436565","16","2195301","0" "664700792","52","1099970","0"
Following is the relevant piece of the shell script I wrote:
sqlplus -s $sql_user/$sql_password@$sid << eof >> /dev/null set feedback off set term off set linesize 1500 set pagesize 11000 --set colsep , --set colsep '","' set trimspool on set underline off set heading on --set headsep $ set newpage none spool "$folder$filename$ext" select '"'||PCL_CARRIER_NAME||'","'||SITETX_EQUIP_ID||'","'||SITETX_SITE_STAT||'","'||SITETX_CREATE_DATE||'","'||ADVTX_VEH_WT||'"' from cvo_admin.MISSING_HOST_SITE_TX_IDS; spool off
(I have used some commented statements in, to signify the things that I tried but couldn't get to work)
The output I receive is:
'"'||PCL_CARRIER_NAME||'","'||SITETX_EQUIP_ID||'","'||SITETX_SITE_STAT||'","'||SITETX_CREATE_DATE||'","'||ADVTX_VEH_WT||'"' "TRANSPORT INC","113","00000000","25-JAN-13 10.17.51 AM","" "TRANSPORT INC","1905","00000000","25-JAN-13 05.06.44 PM","0"
Which shows that the header is messed up - it is literally printing the whole string that should have been interpreted as an sql statement, as is the case with the data displayed.
Options I am considering:
1) Using colsep
set colsep '","' spool select * from TABLE spool off
This introduces other problems as the data having leading and trailing spaces, first and the last values in the files are not enclosed by quotes
HOST_SITE_TX_ID"," SITE_ID" " 12345"," 16" " 12345"," 21
I concluded that this method gives me more heartburn than the one I described earlier.
2) Getting the file and use a regex to modify the header.
3) Leaving the header altogether and manually adding a header string at the beginning of the file, using a script
Option 2 is more doable, but I was still interested in asking, if there might be a better way to format the header somehow, so it comes in a regular csv, (comma delimited, double quote bounded) format.
I am looking to do as less hard coding as possible - the table I am exporting has around 40 columns and I am currently running the script for around 4 million records - breaking them in a batch of around 10K each. I would really appreciate any suggestions, even totally different from my approach - I am a programmer in learning.

Sam B over 3 yearshow is this an answer??? he clearly said and I confirm adding colsep doesn't work all the time
