例如，
ops$tkyte@ORA10GR1> create table t1
2 ( x int primary key,
3 y varchar2(25),
4 z date
5 )
6 organization index;
Table created.
使用一下方法查看详细定义语句：
ops$tkyte@ORA10GR1> select dbms_metadata.get_ddl( 'TABLE', 'T1' ) from dual;
S_METADATA.GET_DDL('TABLE','T1')
-----------------------------------------------------------------------------
CREATE TABLE "OPS$TKYTE"."T1"
(
"X" NUMBER(*,0),
"Y" VARCHAR2(25),
"Z" DATE,
PRIMARY KEY ("X") ENABLE
)
ORGANIZATION INDEX

在此基础上可以进行修改。
注意：select dbms_metadata.get_ddl( 'TABLE', 'T1' ) from dual;中“ 'TABLE', 'T1'”均要大写！
