### 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 2.0.2 ### What's Wrong? When selecting SELECT @@variables, query does not return column names in 2.0.2 compared to previous versions. This causes Mysql clients that check connection information to fail on connect. ### What You Expected? ```sql SELECT @@max_allowed_packet, @@character_set_client, @@character_set_connection, @@license, @@sql_mode, @@lower_case_table_names; ``` Query Results for Doris <2.0.1.1 ``` @@max_allowed_packet | @@character_set_client | @@character_set_connection | @@license | @@sql_mode | @@lower_case_table_names 1048576 | utf8 | utf8 | Apache License, Version 2.0 | | 0 ``` <img width="2232" alt="Screenshot 2023-10-14 at 6 03 11 PM" src="https://github.com/apache/doris/assets/544500/8f5bc7cf-c8a1-48e4-96f0-2d4194ce6162"> We expect to see "@@max_allowed_packet | @@character_set_client | @@character_set_connection | @@license | @@sql_mode | @@lower_case_table_names" returned. Query Results for Doris 2.0.2 BUG ``` 1048576 | 'utf8' | 'utf8' | 'Apache License, Version 2.0' | '' | 0 1048576 | utf8 | utf8 | Apache License, Version 2.0 | | 0 ``` <img width="2236" alt="Screenshot 2023-10-14 at 6 04 09 PM" src="https://github.com/apache/doris/assets/544500/049182ea-32ac-4303-9325-0ada055c1a2a"> ### How to Reproduce? Run the following query on Doris 2.0.2: ```sql SELECT @@max_allowed_packet, @@character_set_client, @@character_set_connection, @@license, @@sql_mode, @@lower_case_table_names; ``` ### Anything Else? _No response_ ### Are you willing to submit PR? - [ ] 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.
