Hi,

I am writing a shopping cart and need to find out how many items in the table match the given criteria.

I can search through the table and get each record until there are no more matches and increment a counter using code like the code below - but there must be a better way - all I need to know is the number of records which match the select criteria.

Maybe there is some kind of select 'count' where cookieid='002' or something like that - if someone could let me know this I would be greatfull.

I could achive what I want using the following code but it's going to be pretty sloppy to have to step through each matching record when I probably don't need to.

        Set lMyDB = DBEngine.OpenDatabase("c:\ecommerce\eshop.mdb")
        Set lMYRs = lMyDB.OpenRecordset("cart", dbOpenDynaset)

        lMYRs.FindFirst "cookieid=" + cookieid$
       
        If lMYRs.NoMatch = False Then
            ' First match has been found
            ' Start a loop for counting additional matches
            Do
            recordcount = recordcount + 1
                lMYRs.FindNext "cookieid=" + cookieid$

               
            Loop While lMYRs.NoMatch = False

        Else
            ' No items found
       
        End If


        lMYRs.Close
        lMyDB.Close
        Set lMYRs = Nothing
        Set lMyDB = Nothing


Thanks

I cannot think of any other better way then this below.

Dim lMyDB As Database, lMYRs As Recordset
Set lMyDB = DBEngine.OpenDatabase("c:\ecommerce\eshop.mdb")
Set lMYRs = lMyDB.OpenRecordset("Select * from cart where cookieid=" & cookieid$)
If lMYRs.RecordCount > 0 Then lMYRs.MoveLast
MsgBox lMYRs.RecordCount & " records have been found."
