How do I implement pagination in SQL for MS Access?

Question

I\'m accessing a Microsoft Access 2002 database (MDB) using ASP.NET through the OdbcConnection class, which works quite well albeit very slowly.

If you wish to apply paging in MS Acces use this

SELECT *
FROM (
    SELECT Top 5 sub.ClientCode
    FROM (
        SELECT TOP 15 tblClient.ClientCode
        FROM tblClient
        ORDER BY tblClient.ClientCode
    ) sub
   ORDER BY sub.ClientCode DESC
) subOrdered
ORDER BY subOrdered.ClientCode

Where 15 is the StartPos + PageSize, and 5 is the PageSize.

EDIT to comment:

The error you are receiving, is because you are trying to reference a column name assign in the same level of the query, namely rownumber. If you were to change your query to:

SELECT *
FROM (
    SELECT ClientCode,
           (SELECT COUNT(c2.ClientCode)
            FROM tblClient AS c2
            WHERE c2.ClientCode <= c1.ClientCode) AS rownumber                
    FROM tblClient AS c1
)
WHERE rownumber BETWEEN 0 AND 15

It should not give you an error, but i dont think that this is the paging result you want.
