PostgreSQL - DataError: nieprawidłowa składnia wejściowa dla typu numerycznego: "Produkt"

Question

Więc nie rozumiem, dlaczego daje ten błąd. jest wartością pola "Numer produktu"? .. Mam zapytanie z UNION ALL, co powoduje, że pierwszy wiersz pokazuje całkowitą sumę innych wierszy. Moje zapytanie jest dość długie, więc nie opublikuję go (ale jeśli będzie to konieczne, opublikuję to).

Więc najpierw dam fragment mojego kodu:

with w as (
SELECT 
... 
CASE x.variants WHEN x.variants THEN x.product || ' - ' || x.variants else x.product END as product 
... 

) 

SELECT 
... 
'Product' as product, 
... 
UNION ALL 
SELECT * FROM w 

Więc używam kolumny produkt, aby pokazać się w pierwszym rzędzie jako „produkt” (bo nie trzeba obliczyć w tej dziedzinie . pierwszy wiersz Ale obliczyć pozostałe pola łącznie)

Gdy uruchomię mojej kwerendy wyprowadza ten błąd:

DataError: invalid input syntax for type numeric: "Product" 
LINE 104: 'Product' as product,

Answer 1

Ok dowiedziałem się, co się stało. Głupi ja:). Dało to błąd, ponieważ główna część zapytania, wybór kolejności kolumn była błędna (mimo że w moim systemie jest ona porządkowana przy użyciu interfejsu graficznego, ale w tym przypadku, przy użyciu UNION ALL, kolumny muszą być również poprawnie zamawiane). Zmieniłem więc kolejność tak, aby była taka sama jak w pierwszym rzędzie i zadziałało.
