ClickHouseColumn bug when parsing a tuple type

[jnd77]

Hi.
There is a bug or unexpected behavior in ClickHouseColumn when parsing a tuple type:

ClickHouseColumn.parse("col_name Tuple(s String, i Int64)") is throwing the following exception:

java.lang.IllegalArgumentException: Unknown data type: s String

My use case retrieves the types with a DESCRIBE TABLE query and parsing them via ClickHouseColumn.parse.

Thanks @jnd77, I'm aware of this. Actually it's been fixed in my local in order to support Object/JSON data type.

Ok great. :)

ClickHouseColumn was enhanced to support both Object(a String, i Int64) and Tuple(a String, i Int64). However, as mentioned in ClickHouse/ClickHouse#35461, ClickHouse server will only return the latter even the column is defined as Object('JSON').

Looks like still have issue :<

-- not working
select tuple(1)::Tuple(i Int32)

-- workaround(longer field name)
select tuple(1)::Tuple(i1 Int32)
