[I] [Bug] SELECT @@variables does not return column names due to regression introduced in 2.0.2 [doris]
geoffreytran opened a new issue, #25445:
URL: https://github.com/apache/doris/issues/25445
### 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
```

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
```

### 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;
```
