Bye~

The type of id is : Nullable(Tuple(Nullable(Int32), Nullable(Nullable(String))))

But in databend-py type of id is :Tuple(Int32 NULL, Array(String NULL

ignore a ) quote and The type is not null.

cat ~/a.py                                                                                                                                                                                  ✔  2m 5s   eason@databend-arch1

[('id', 'Tuple(Int32 NULL, Array(String NULL')]
[('NULL',)]

@TCeason The raw response in python is [{'name': 'id', 'type': 'Nullable(Tuple(Int32 NULL, Array(String NULL) NULL))'}] as shown in the following pic:

So I need to shown the colum type as : Nullable(Tuple(Int32 NULL, Array(String NULL) NULL))
