Before you can create a tablespace, you must create a database to contain it. The primary tablespace in any database is the
SYSTEM
tablespace, which contains information basic to the functioning of the database server, such as the data dictionary and the system rollback segment. The
SYSTEM
tablespace is the first tablespace created at database creation. It is managed as any other tablespace, but requires a higher level of privilege and is restricted in some ways. For example, you cannot rename or drop the
SYSTEM
tablespace or take it offline.
The
SYSAUX tablespace, which acts as an auxiliary tablespace to the SYSTEM tablespace, is also always created when you create a database. It contains the schemasused by various Oracle products and features, so that those products do not require their own tablespaces. As for the SYSTEM tablespace, management of theSYSAUX tablespace requires a higher level of security and you cannot rename or drop it. The management of the SYSAUX tablespace is discussed separately in"Managing the SYSAUX Tablespace"
To create a new tablespace, use the SQL statement
CREATE TABLESPACE or CREATE TEMPORARY TABLESPACE
. You must have the
CREATE TABLESPACE
system privilege
to create a tablespace. Later, you can use the
ALTER TABLESPACE or ALTER DATABASE
statements to alter the tablespace. You must have the
ALTER TABLESPACE
or
ALTER DATABASE
system privilege, correspondingly. ---
U
se the
CREATE UNDO TABLESPACE
statement to create a special type of tablespace called an
undo tablespace.
- 创建表空间,具体参考oracle 官方文档
CREATE TABLESPACE index_new DATAFILE '+data' SIZE 256M autoextend on next 1M maxsize 4G extent management local;
- 查看表空间
select t.name,d.name from v$tablespace t,v$datafile d where t.ts#=d.ts#；- 生成创建表空间的脚本
SQL> spool C:\get_ddl_tablespace.sql
SQL> SELECT 'Select dbms_metadata.get_ddl('
