表空间相关操作

--1、查看表在那个表空间 select tablespace_name,table_name from user_talbes where table_name='test';

--2、获取用户的默认表空间 select username, DEFAULT_TABLESPACE from dba_users where username='MXH';

--3、查看表空间所有的文件 select * from dba_data_files where tablespace_name='USERS';

--4、查看表空间使用情况：

SELECT tbs 表空间名,

sum(totalM) 总共大小M,

sum(usedM) 已使用空间M,

sum(remainedM) 剩余空间M,

sum(usedM)/sum(totalM)*100 已使用百分比,

sum(remainedM)/sum(totalM)*100 剩余百分比

FROM(

SELECT b.file_id ID,

b.tablespace_name tbs,

b.file_name name,

b.bytes/1024/1024 totalM,

(b.bytes-sum(nvl(a.bytes,0)))/1024/1024 usedM,

sum(nvl(a.bytes,0)/1024/1024) remainedM,

sum(nvl(a.bytes,0)/(b.bytes)*100),

(100 - (sum(nvl(a.bytes,0))/(b.bytes)*100))

FROM dba_free_space a,dba_data_files b

WHERE a.file_id = b.file_id

GROUP BY b.tablespace_name,b.file_name,b.file_id,b.bytes

ORDER BY b.tablespace_name

)

GROUP BY tbs

--5、扩展表空间 alterdatabase datafile 'D:\ORACLE\PRODUCT\ORADATA\TEST\USERS01.DBF' resize 50m;

--自动增长 alterdatabase datafile 'D:\ORACLE\PRODUCT\ORADATA\TEST\USERS01.DBF' autoextend onnext 50m maxsize 500m;

--增加数据文件 alter tablespace USERS add datafile 'd:\users02.dbf' size 5m;

一些查询语句 没有注释 自用：

INSERT INTO YX_HIGHBANDWIDTH

SELECT *

FROM YX_201405

WHERE to_date(STARTDATE,'yyyy-mm-dd') >= to_date('2014-05-27','yyyy-mm-dd')

AND to_date(ENDDATE,'yyyy-mm-dd') <= to_date('2014-05-31','yyyy-mm-dd');

select count(*) from YX_HIGHBANDWIDTH

INSERT INTO YX_HIGHBANDWIDTH

SELECT *

FROM YX_201406

WHERE to_date(STARTDATE,'yyyy-mm-dd') >= to_date('2014-06-01','yyyy-mm-dd')

AND to_date(ENDDATE,'yyyy-mm-dd') <= to_date('2014-06-02','yyyy-mm-dd');

FROM dba_tablespaces t, dba_data_files d

WHERE t.tablespace_name = d.tablespace_name

GROUP BY t.tablespace_name;

round((total - free) / total, 4) * 100 "使用率 %"
