size 32m
autoextend on
next 32m maxsize 2048m

/*第1步：创建临时表空间 */
create temporary tablespace user_temp
tempfile 'D:oracleoradataOracle9iuser_temp.dbf'
size 50m
autoextend on
next 50m maxsize 20480m

/*第2步：创建数据表空间 */
create tablespace user_data
logging
datafile 'D:oracleoradataOracle9iuser_data.dbf'
size 50m
autoextend on
next 50m maxsize 20480m

/*第3步：创建用户并指定表空间 */
create user username identified by password
default tablespace user_data
temporary tablespace user_temp;

/*第4步：给用户授予权限 */
grant connect,resource,dba to username;
