开发环境直连数据库，生产环境直连 cobar ，出现问题了

Error updating database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; Error occurs around this fragment: { UPDATE heart_bea}. Error cause: SQL syntax error!

在开发环境测试过了，没有问题呢，

No files or tests are named. First compare the failing UPDATE around “UPDATE heart_bea” when sent directly to MySQL and when sent through Cobar, using a production-like configuration and the complete SQL from the error. Done means the statement succeeds through Cobar or the incompatible SQL behavior is reproduced and documented with a minimal case.
