Oracle查询数据库中所有表的记录数
select t.table_name,t.num_rows from user_tables t
查询结果如下
若以上SQL查找不到，执行如下脚本即可：
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
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;

之后，再查select table_name, count_rows(table_name) nrows from user_tables ，OK
