Effectively, after removing the column names from x(jina, namba, nasaba_1) it works now. Thank you very much. But then I don't understand the advantage or inconvenience of naming or not naming the columns there. Is there any explanation somewhere?
SQL is big on providing ways to give aliases/names to things. It just boils down to readability or, more often, conventions, as to which ones to use. The CTE column names clause doesn’t get used much that I have seen. You have to write a full query inside the CTE anyway so column aliases are more conventional.
