Hello All,
I am new to Teradata. I encountered a weird error and I am not sure about the cause of this error. I am trying to build a view using some select statement. Pasted below is the select statement -

When I tried to use replace or create view for the same select statement, which worked perfectly fine by the way, it showed error 3706 : DataType 'xml_hierarchy' does not match a defined data type name.
I am not sure how to eradicate this issue. Any help would be appreciated.
thanks,
