oracle 查询所有表的记录数 SQL
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、然后通过计算函数进行统计
select table_name, count_rows(table_name) nrows from user_tables order by nrows desc

上面的数据需要验证
