Przykłady SQL do raportów

Użyteczne konstrukcje i funkcje językowe SQL

--Formatuje datę
SELECT to_char(d.adddat, 'YYYY-MM-DD') FROM documents d; 

-- Pobiera rok
select extract(YEAR from CURRENT_DATE);

-- Oblicza czas który upłynął od daty do daty (np. na realizacji zadania)
((extract(EPOCH FROM d.rlend_) - extract(EPOCH FROM d.rlstrt))/3600)::numeric(12,2) AS duration

-- Zamienia liczbę sekund na ciąg: H:M:S - np. 00:30:03
SELECT (1803 || 's')::interval

-- Formatuje kwotę z pól tekstowych np. z formularzy customowych
select cast(regexp_replace(regexp_replace('301 110,43',' ',''),',', '.') as numeric(12,2)) + 12.50;

-- Warunkowo koloruje pole
CASE WHEN p.pr_sta = 1 THEN '<div style="color: red">Rozpoczęte</div>' WHEN p.pr_sta = 2 THEN 'W trakcie realizacji' WHEN p.pr_sta = 3 THEN 'Zakończone' END  AS status,

-- Wybiera te rekordy których data jest w tym tugodniu
to_char(CURRENT_DATE, 'WW') = to_char (adddat, 'WW')

-- wybiera rekordy nie starsze niż miesiąc
AND dcr.adddat > CURRENT_DATE - interval '1 month'

-- ogranicza filtr jeśli {value} zwraca pusty string
CASE WHEN NULLIF('{value}', '') IS NULL THEN adduid IS NULL ELSE adduid IN ({value}) END
