Static variable in SQL

[pando]

dont understand what you really mean but I will try...

declare
  l_append_tab varchar2(100);
begin
  for i in (select * from dba_tables
            where owner in ('LSC', 'TEST')
            order by owner, table_name)
  loop
    if i.owner = 'LSC'
    then
    l_append_tab := i.owner||'.'||i.table_name;
    dbms_output.put_line(l_append_tab);
    end if;
  end loop;
end;
/
