【问题描述】*：
操作系统win10，数据库版本为DM8, 驱动依赖为DM8:

        <dependency>
            <groupId>com.dameng</groupId>
            <artifactId>DmJdbcDriver18</artifactId>
            <version>8.1.1.193</version>
        </dependency>

本来连接正常，后面为了兼容mysql，修改了配置，红框处修改为4，如图：

重启数据库后，然后就报以下错误：

后面配置修改回0，重启数据库后还是报相同的错误，这个问题要怎么解决？
