--查询SCOTT用户中所有表的记录数
declare
  v_count number;
  query   varchar2(4000);
begin
  for i in (select table_name
              from all_tables
             where owner = 'SCOTT'
             order by 1) loop
    query := 'select count(*) from "' || i.table_name || '"';
    execute immediate query
      into v_count;
    dbms_output.put_line(rpad(i.table_name, 35, ' ') || '-----' || v_count);
  end loop;
end;



--查看分区表的行数
declare
  v_count number;
  query   varchar2(4000);
begin
  for i in (select table_name,partition_name
              from user_tab_partitions
             where table_name='DDM_TRANSACTION_LOG'
             order by 1) loop
    query := 'select count(*) from ' || i.table_name || ' partition(' || i.partition_name || ')' || '';
    execute immediate query
      into v_count;
    dbms_output.put_line(rpad(i.partition_name, 35, ' ') || '-----' || v_count);
  end loop;
