往cobar写数据的时候报错

[job-0] ERROR RetryUtil - Exception when calling callable, 异常Msg:Code:[DBUtilErrorCode-10], Description:[连接数据库失败. 请检查您的 账号、密码、数据库名称、IP、Port或者向 DBA 寻求帮助(注意网络环境).]. - 具体错误信息为：java.sql.SQLException: Unknown system variable 'language'

Start with the reported Cobar write failure and trace the Java database connection path that produces DBUtilErrorCode-10. Investigate the java.sql.SQLException for the unknown system variable 'language' and determine the affected database compatibility or configuration; done means the reported write no longer fails and the error case is covered by an appropriate test.
