Op voorwaarde dat u unieke indices heeft op beide (ProductID, CategoryID)
en (ProductID, InvoiceID)
:
SELECT ProductID
FROM (
SELECT ProductID
FROM ProductInvoice
WHERE InvoiceID IN (1, 2)
UNION ALL
SELECT ProductID
FROM ProductCategory pc
WHERE CategoryID IN (3, 4)
) q
GROUP BY
ProductID
HAVING COUNT(*) = 4
of, als uw waarden worden doorgegeven in CSV
snaren:
WITH catids(value) AS
(
SELECT DISTINCT CAST([value] AS INT)
FROM dbo.split(@categories, ' '))
),
(
SELECT DISTINCT CAST([value] AS INT)
FROM dbo.split(@invoices, ' '))
)
SELECT ProductID
FROM (
SELECT ProductID
FROM ProductInvoice
WHERE InvoiceID IN
(
SELECT value
FROM invoiceids
)
UNION ALL
SELECT ProductID
FROM ProductCategory pc
WHERE CategoryID IN
(
SELECT value
FROM catids
)
) q
GROUP BY
ProductID
HAVING COUNT(*) =
(
SELECT COUNT(*)
FROM catids
) +
(
SELECT COUNT(*)
FROM invoiceids
)
Merk op dat in SQL Server 2008
u kunt parameters met tabelwaarde doorgeven aan de opgeslagen procedures.
