Per una tabella di quelle dimensioni, utilizzare una Common-Table Expression (CTE) e ROW_NUMBER; usa una piccola funzione per calcolare i record da riportare in base a @PageNumber
e @PageSize
variabili (o come vuoi chiamarle). Semplice esempio da una delle nostre stored procedure:
-- calculate the record numbers that we need
DECLARE @FirstRow INT, @LastRow INT
SELECT @FirstRow = ((@PageNumber - 1) * @PageSize) + 1,
@LastRow = ((@PageNumber - 1) * @PageSize) + @PageSize
;
WITH CTE AS
(
SELECT [Fields]
, ROW_NUMBER() OVER (ORDER BY [Field] [ASC|DESC]) as RowNumber
FROM [Tables]
WHERE [Conditions, etc]
)
SELECT *
-- get the total records so the web layer can work out
-- how many pages there are
, (SELECT COUNT(*) FROM CTE) AS TotalRecords
FROM CTE
WHERE RowNumber BETWEEN @FirstRow AND @LastRow
ORDER BY RowNumber ASC
