Hi,

I needed script to export one table partition every day.
-----------------------------------------------------------------
I wrote the script but It is not running properly.

#!/bin/bash


# Oracle Environment Variables

ORACLE_SID=dwsales1
export ORACLE_SID
CONNECT=salesqa2/salesqa2@dwsales1
#CONNECT=sys/tera1234@dwsales1

# set oracle environment
#if [ -f /home/oracle/scripts/orarpt.sh ]; then
# . /home/oracle/scripts/orarpt.sh
#fi


partition_name=`sqlplus -s / as sysdba <<EOF
set heading off
set feedback off
set echo off
set term off
select 'PIN_MESSAGE_D' || to_char(sysdate -1,'YYYYMMDD') from dual;
exit
EOF`
echo $partition_name

EXPORT_DIRECTORY=MANDBA_DUMP_DIR

#expdp $CONNECT directory=$EXPORT_DIRECTORY dumpfile=$partition_name.dmp logfile=$partition_name.log tables=PIN_MESSAGE:$partition_name

declare
V_partname Varchar2(240);
begin
select 'PIN_MESSAGE_D' || to_char(sysdate -1,'YYYYMMDD') into V_partname from dual;

end;


select to_char(sysdate, 'Dy DD-Mon-YYYY HH24:MI:SS') from dual;

spool off ;

--------------------------------------------------------------
(I am exporting this partition Successfully, When I ran directly in Unix).
#expdp CONNECT directory=EXPORT_DIRECTORY dumpfile=partition_name.dmp logfile=partition_name.log tables=EMPLOYEES:partition_name.
--------------------------------------------------------------

But When I Insert this export command in Unix Script it is not working.

Can Anyone Modify/Rewrite the script.

My Requirement is: I need to export the Yesterday Partition.

If you "termout off" then you will have nothing in "partition_name" variable.
In addition you don't need to pass to Oracle to get 'PIN_MESSAGE_D'||YYYYMMDD in your variable just do it in Unix:
> echo 'PIN_MESSAGE_D'`date +"20%y%m%d"`
PIN_MESSAGE_D20100526

Regards
Michel

WRONG:
$ cat k0
#!/usr/bin/ksh
partition_name=`sqlplus -s / <<EOF
set head off feed off echo off
set term off
select 'PIN_MESSAGE_D' || to_char(sysdate -1,'YYYYMMDD') from dual;
exit
EOF`
echo $partition_name

$ ./k0
PIN_MESSAGE_D20100615
$
