One all null row is always in discard file of sqlldr

Question

Hi All,
My DB is 11.1.
I used spool to generate a formatted flat data and load it to oracle with sqlldr. I found everything was fine except that the discard file was always generated.
Its content is ~~~, which is line seperator specified in control file.
But before loading, I cleansed the data with the following command and it seems that the empty line should be in the data file any more.
sed '/^ *$/d' S_PROD_INT_PLC_BK_LEON.dat > S_PROD_INT_PLC_BK_LEON.dat1
mv S_PROD_INT_PLC_BK_LEON.dat1 S_PROD_INT_PLC_BK_LEON.dat
sed '/^~~~$/d' S_PROD_INT_PLC_BK_LEON.dat > S_PROD_INT_PLC_BK_LEON.dat1
mv S_PROD_INT_PLC_BK_LEON.dat1 S_PROD_INT_PLC_BK_LEON.dat
Could anyone give me some ideas on this?
Best regards,
Leon

Hi Kim Berg Hansen
Thank you for your reply. Besides the patterns in sed, I aslo greped the'grep '^ *~~~ *$' S_SRC_PLC_BK_LEON.dat' but no row returned.
Actually the file was generated by myself, and I think the '~~~' can only be in the last of one line.
The sample spool file looks like:
SET term OFF
SET heading OFF
SET feedback OFF
SET echo OFF
set linesize 32767
set trimspool on
SET NEWPAGE NONE
spool /home/bs7822/leon/S_SRC_PLC_BK_LEON.dat
alter session set nls_date_format = 'yyyymmdd hh24:mi:ss';
SELECT
ROW_ID||'|'||
SRC_NUM||'|'||
SUB_TYPE||'|'||
X_VISIT_SS_OVER||'~~~' FROM S_SRC_PLC_BK
where rownum<=500;
spool offYou say
Or perhaps it is on the last line and maybe missing the EOL?I checked the file with vi editor. When I used shift+G, I got to the last line of data that is not empty.
Best regards,
Leon
