报错“不是可以识别的 内置函数名称”
首页登录后就提示“'SUBSTR' 不是可以识别的 内置函数名称。”这个是问题是更换了数据库后出现的，原来使用的是mysql，没有出现过，换成sqlserver，只要首页一刷新，就会报这个错。
下面是错误信息。
全局处理异常捕获:

<!-- 在线聊天工具-->
<dependency>
<groupId>org.p3framework</groupId>
<artifactId>jeecg-p3-biz-chat</artifactId>
<version>1.0.2</version>
</dependency>
我把这个注释掉，再启动就报错了，别的查不到SUBSTR，请问下是应该把哪几个注释掉才正确。
解决了，谢谢。 将pom.xml中在线聊天工具注释掉，并把JeecgMinidaoDao.java中导入的一个包也注解掉
该问题就能解决了。
