### Cause: java.sql.SQLSyntaxErrorException: ORA-00911: 无效字符

前言

使用MyBatis进行SQL查询，报出SQL异常，原因为SQL语句最后结束加了分号( )()

 org.springframework.jdbc.BadSqlGrammarException: 
### Error querying database.  Cause: java.sql.SQLSyntaxErrorException: ORA-00911: 无效字符

### The error may exist in com/df/dao/RunOverviewMapper.java (best guess)
