PLS-00363: expression '0' cannot be used as an assignment target

[LKBrwn_DBA]

Another way is:

TargetInstance=""
SourceInstance=""
Rerun="N"
ReturnStatus=0

sqlplus -s /nolog << !EOF >> $LOG 2>&1
whenever sqlerror exit 99
connect apps/$PWD
var l_return_status number;
exec :l_return_status := 0;
declare
begin
  CLONE_SETUP.clone_main('$TargetInstance','$SourceInstance','$Rerun', :l_return_status);
  if :l_return_status = 0 then
    commit;
  else
    rollback;
  end if;
end;
/
exit :l_return_status
!EOF
ReturnStatus=$?
if [ ReturnStatus -eq 0 ]; then
  echo 'Rapid Clone succeeded, Commit performed'
else 
  echo 'Rapid Clone failed, Rollback performed'
fi
exit
