### What problem does this PR solve?
This update fixes an issue where the `SHOW FULL COLUMNS` statement still
displayed `version` for `date`, `datetime`, and `decimal` data types. This
change aims for better compatibility with MySQL behavior and BI applications.
```txt
MySQL [(none)]> SHOW FULL COLUMNS FROM `doris_all_types_demo` FROM `tpch`;
