oracle迁移表到新的表空间

姚海芮

1.创建新的表空间
CREATE TABLESPACE bayonet
DATAFILE '/oradata/db/bayonet_01.DBF'
SIZE 2G
AUTOEXTEND ON NEXT 1G MAXSIZE UNLIMITED LOGGING
EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO ;

2.修改用户默认表空间
ALTER USER dbuser DEFAULT tablespace bayonet;

3.创建迁移表到新的表空间SQL执行语句
==普通表：
SELECT 'alter table ' ||table_name || ' move tablespace bayonet;'   
FROM user_all_tables   
WHERE tablespace_name='USERS';
--无子分区
SELECT 'alter table ' ||t1.TABLE_NAME || ' move partition '|| t2.PARTITION_NAME ||' tablespace bayonet;'   
FROM user_all_tables t1,USER_TAB_PARTITIONS t2   
WHERE t1.TABLE_NAME=t2.TABLE_NAME AND t2.tablespace_name='USERS' and t2.subpartition_count>0;

--子分区
SELECT 'alter table ' ||t1.TABLE_NAME || ' move subpartition '|| t2.subpartition_name ||' tablespace bayonet;'   
FROM user_all_tables t1,all_tab_subpartitions t2   
WHERE t1.TABLE_NAME=t2.TABLE_NAME AND t2.tablespace_name='USERS';
SELECT 'alter table ' ||t1.TABLE_NAME || ' modify default ATTRIBUTES FOR partition '|| t2.PARTITION_NAME ||' tablespace bayonet;'   
FROM user_all_tables t1,USER_TAB_PARTITIONS t2   
WHERE t1.TABLE_NAME=t2.TABLE_NAME AND t2.tablespace_name='USERS';

4.创建索引重建的SQL执行语句

select 'alter table '||table_name||' disable primary key;' from user_constraints where constraint_type='P' and R_OWNER='DBUSER';
SELECT 'alter index ' ||index_name || ' rebuild  tablespace bayonet;'
FROM user_indexes  
WHERE index_type='NORMAL' AND DROPPED='NO' AND  
TABLE_NAME IN (
SELECT TABLE_NAME
FROM user_all_tables
WHERE tablespace_name='users'
);
select 'alter table '||table_name||' enable primary key;' from user_constraints
where constraint_type='P' and R_OWNER='DBUSER';



5.创建表分区
