Mam stosunkowo dużą tabelę (obecnie 2 miliony rekordów) i chciałbym wiedzieć, czy można poprawić wydajność zapytań ad-hoc. Kluczowe jest tutaj słowo ad-hoc . Dodawanie indeksów nie jest opcją (istnieją już indeksy w kolumnach, które są najczęściej zadawane).
Uruchomienie prostego zapytania w celu zwrócenia 100 ostatnio zaktualizowanych rekordów:
select top 100 * from ER101_ACCT_ORDER_DTL order by er101_upd_date_iso desc
Trwa kilka minut. Zobacz plan wykonania poniżej:
Dodatkowe szczegóły ze skanu tabeli:
SQL Server Execution Times:
CPU time = 3945 ms, elapsed time = 148524 ms.
Serwer jest dość wydajny (z pamięci 48 GB RAM, 24-rdzeniowy procesor) z systemem SQL Server 2008 R2 x64.
Aktualizacja
Znalazłem ten kod, aby utworzyć tabelę z 1 000 000 rekordów. Pomyślałem, że mógłbym wtedy uruchomić SELECT TOP 100 * FROM testEnvironment ORDER BY mailAddress DESC
na kilku różnych serwerach, aby sprawdzić, czy moje prędkości dostępu do dysku na serwerze są słabe.
WITH t1(N) AS (SELECT 1 UNION ALL SELECT 1),
t2(N) AS (SELECT 1 FROM t1 x, t1 y),
t3(N) AS (SELECT 1 FROM t2 x, t2 y),
Tally(N) AS (SELECT TOP 98 ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM t3 x, t3 y),
Tally2(N) AS (SELECT TOP 5 ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM t3 x, t3 y),
Combinations(N) AS (SELECT DISTINCT LTRIM(RTRIM(RTRIM(SUBSTRING(poss,a.N,2)) + SUBSTRING(vowels,b.N,1)))
FROM Tally a
CROSS JOIN Tally2 b
CROSS APPLY (SELECT 'B C D F G H J K L M N P R S T V W Z SCSKKNSNSPSTBLCLFLGLPLSLBRCRDRFRGRPRTRVRSHSMGHCHPHRHWHBWCWSWTW') d(poss)
CROSS APPLY (SELECT 'AEIOU') e(vowels))
SELECT IDENTITY(INT,1,1) AS ID, a.N + b.N AS N
INTO #testNames

CROSS JOIN Combinations b;
SELECT IDENTITY(INT,1,1) AS ID, firstName, secondName
INTO #testNames2
FROM (SELECT firstName, secondName
FROM (SELECT TOP 1000 --1000 * 1000 = 1,000,000 rows
N AS firstName
FROM #testNames
ORDER BY NEWID()) a
CROSS JOIN (SELECT TOP 1000 --1000 * 1000 = 1,000,000 rows
N AS secondName
FROM #testNames
ORDER BY NEWID()) b) innerQ;
SELECT firstName, secondName,
firstName + '.' + secondName + '@fake.com' AS eMail,
CAST((ABS(CHECKSUM(NEWID())) % 250) + 1 AS VARCHAR(3)) + ' ' AS mailAddress,
(ABS(CHECKSUM(NEWID())) % 152100) + 1 AS jID,
IDENTITY(INT,1,1) AS ID
INTO #testNames3
FROM #testNames2
SELECT IDENTITY(INT,1,1) AS ID, firstName, secondName, eMail,
mailAddress + b.N + b.N AS mailAddress
INTO testEnvironment
FROM #testNames3 a
INNER JOIN #testNames b ON a.jID = b.ID;
--CLEAN UP USELESS TABLES
DROP TABLE #testNames;
DROP TABLE #testNames2;
DROP TABLE #testNames3;
Ale na trzech serwerach testowych zapytanie przebiegło niemal natychmiast. Czy ktoś może to wyjaśnić?

Dziękuję za komentarze - proszę, nie przestawajcie ich przekazywać ... skłoniły mnie do zmiany indeksu klucza podstawowego z nieklastrowego na klastrowy z dość interesującymi (i nieoczekiwanymi?) Wynikami.
Nieklastrowy:
SQL Server Execution Times:
CPU time = 3634 ms, elapsed time = 154179 ms.
Klastrowany:
SQL Server Execution Times:
CPU time = 2650 ms, elapsed time = 52177 ms.
Jak to jest możliwe? Bez indeksu w kolumnie er101_upd_date_iso, jak można użyć skanowania indeksu klastrowego?
Zaktualizuj 3
Zgodnie z żądaniem - to jest skrypt tworzenia tabeli:
