1。执行
create or replace function count_rows(table_name in varchar2,
 owner in varchar2 default null)
 return number authid current_user IS
 num_rows number;
 stmt varchar2(2000);
begin
 if owner is null then
 stmt := 'select count(*) from "' || table_name || '"';
 else
 stmt := 'select count(*) from "' || owner || '"."' || table_name || '"';
 end if;
 execute immediate stmt
 into num_rows;
 return num_rows;
end;

2.执行
select table_name, count_rows(table_name) nrows
 from user_tables
 order by table_name asc
