При условие, че имате уникални индекси и на двата (ProductID, CategoryID)
и (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
или, ако вашите стойности са предадени в CSV
низове:
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
)
Имайте предвид, че в SQL Server 2008
можете да предавате параметри с таблична стойност в съхранените процедури.
