### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version mysql-java-connector: 5.1.13 mysql: 5.7 envrionment: spring-boot、DruidDatasource doris ： 1.1.5 ### What's Wrong? <img width="1395" alt="image" src="https://github.com/apache/doris/assets/40427110/2bf27912-6672-4db6-994f-41f9f6e412b6";> As you can see, when we use mysql version 5.1.13, there will be an error that the have_query_cache parameter is missing. This will disappear after upgrading to 8.x. However, in our company, the mysql version has been fixed to 5.1.13 and cannot be easily upgraded, otherwise business production problems will occur. ### What You Expected? We hope that the community can solve this parameter problem and be compatible with the java connector of the lower version of mysql 5.1.x ### How to Reproduce? _No response_ ### Anything Else? _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
