【问题描述】*java程序是在win10系统中运行的，jdk版本为1.8，jdbc驱动为DmJdbcDriver18，版本是8.1.2.141。
在执行以下两个ddl时会报错：
1.ALTER TABLE DM_TWO DROP PRIMARY KEY
2.alter table DM_TWO add primary key (TWO_NL)
这两个ddl是分开执行的。
java程序在启动后，第一次执行以上两个ddl是肯定不会报错的，第二次执行是肯定会报错的，报错如下：
Caused by: org.springframework.dao.DataIntegrityViolationException:

Error updating database. Cause: dm.jdbc.driver.DMException: 对象定义[DM_TWO]被修改，版本检查失败

The error may exist in com/je/ibatis/extension/mapper/MetaBaseMapper.xml
