Doris add or modify column

[XinSuiNian]

I want to add or modify a field in Doris. I would like to first check if the field exists, and then decide whether to add or modify the field based on that.

like this : ALTER TABLE if exists test_read_data ADD COLUMN if not exists aaabbb INT DEFAULT "0" ;

The content here is not what I'm looking for. I need to check if a field exists before adding or modifying it. If the field exists, then perform the modification; if it does not exist, then do nothing.

I did not find any relevant information in the documentation.
