Delete Oracle Table Field Comment

To remove a field’s comment in a table, you can use the ALTER TABLE statement to set the field’s comment to NULL. For example, if the table name is table_name and the field name is column_name, you can use the following statement to delete the field comment:

ALTER TABLE table_name MODIFY column_name COMMENT '';

This will remove the comment information of the column_name field. Please note that this will only delete the comment of the field, not the field itself.
