问个sql语句,该如何处理

问个sql语句
现在数据库中的某个字段的数据是这样的
GENERATE
SUBMIT
APPROVE
APPROVAL_REJECT
SUBMIT
APPROVE
APPROVE
APPROVAL_REJECT
SUBMIT
APPROVE
APPROVE
APPROVE
我如何从最后一次SUBMIT开始取数据呢?（如上面，会取出最后四行）


[解决办法]
测试数据：

SQL code

CREATE  TABLE T29(    ID      VARCHAR2(20),    des     VARCHAR2(20));INSERT INTO T29 VALUES('1', 'GENERATE');INSERT INTO T29 VALUES('2', 'SUBMIT');INSERT INTO T29 VALUES('3', 'APPROVE');INSERT INTO T29 VALUES('4', 'APPROVAL_REJECT');INSERT INTO T29 VALUES('5', 'SUBMIT');INSERT INTO T29 VALUES('6', 'APPROVE');INSERT INTO T29 VALUES('7', 'APPROVE');INSERT INTO T29 VALUES('8', 'APPROVAL_REJECT');INSERT INTO T29 VALUES('9', 'SUBMIT');INSERT INTO T29 VALUES('10', 'APPROVE');INSERT INTO T29 VALUES('11', 'APPROVE');INSERT INTO T29 VALUES('12', 'APPROVE');

SQL code
with t as (select 'GENERATE'  a     from dual  union all select 'SUBMIT'          from dual  union all select 'APPROVE'         from dual  union all select 'APPROVAL_REJECT' from dual  union all select 'SUBMIT'          from dual  union all select 'APPROVE'         from dual  union all select 'APPROVE'         from dual  union all select 'APPROVAL_REJECT' from dual  union all select 'SUBMIT'          from dual  union all select 'APPROVE'         from dual  union all select 'APPROVE'         from dual  union all select 'APPROVE'         from dual            ) select a from  (select  a,row_number() over (order by rownum) rn from t  ) c where c.rn>=( select  max(rn) from (select a,row_number() over (order by rownum) rn from t )  where a='SUBMIT' )
