oracle fetch报错,Oralce fetch first ORA-00933 SQL命令未正确结束

项目使用的是MyBatis，之前用的是DB2的数据库，现切换到Oracle时，其中一条SQL语句报错ORA-00933：

select *

from com_transaction

where 1=1

and user_id = ?

order by id desc

fetch first 10 rows only

错误：

Caused by: org.springframework.jdbc.BadSqlGrammarException:

Error querying database. Cause: java.sql.SQLException: ORA-00933: SQL 命令未正确结束

The error may exist in conf-mybatis/biz/ComTransactionDao.xml

The error may involve com.hisun.branch.dao.ComTransactionMapper.getComTransactionByParams-Inline

The error occurred while setting parameters

SQL: select * from com_transaction where 1=1 and user_id = ? order by id desc fetch first 10 rows only;

Cause: java.sql.SQLException: ORA-00933: SQL 命令未正确结束

; bad SQL grammar []; nested exception is java.sql.SQLException: ORA-00933: SQL 命令未正确结束

在想会不会是Oracle不支持fetch first rows only关键字？

fetch first 10 rows only，这个是取前十条的记录吧，在oracle 12c中可以这样写，12c之前的版本要结合ronum进行判断，示例代码：

select *

from (

select t.*, rownum as rn

from com_transaction t

where 1=1

and user_id = ?

order by id desc

)

where rn <= 10

感谢@刑爱明 的答案，另外补充一下，在MyBatis中，“小于等于”符号必须要用CDATA包含起来

where rn <= 10
