I get an error when I use GetRows(adGetRowsRest). I have to use GetRows(-1)
ADODB.Recordset (0x800A0C93)
Operation is not allowed in this context.
/my_cards/set.asp, line 208


Also, I have to check for an array if the query comes back with rows, else I get a type mismatch error.
What could cause this?

Sub GetCards()
    dim strSql, rs, allSRData, SetRows

    strSql = "SELECT SR_CARDS FROM " & strTablePrefix & "SET_ROW " & _
             "WHERE SET_ID = " & SetID & " AND SR_CARDS > 0 AND SR_ROW_TYPE = 4"

    Set rs = Server.CreateObject("ADODB.Recordset")
    rs.open strSql, my_Conn

    if rs.EOF or rs.BOF then
        allSRData = ""
    else
        allSRData = rs.GetRows(-1)    'adGetRowsRest draws an error 
        SetRows = uBound(allSRData,2)
    end if

    rs.close
    set rs = nothing

    if not isArray(allSRData) then  'if allSRData = "" then -draws an error 
        SetCards = 0
        SetUniqueCards = 0
    else
        SetCards = SetRows + 1
    end if
End Sub

I know the docs say getrows() will return an array, but in extensive code I used a few years back I can say that getrows() did not always return an array. Maybe I can find some of that code and the notes I kept back then.

can't find anything that says it returns -1, the MS docs just say it returns an array, good practice would be to check if the recordset was empty before calling getRows. IIRC calling GetRows on an empty recordset errors rather than returning a value.

I used to use getrows() a lot years back, unless something has changed getrows() didn't return an array if you called it on an empty recordset, it used to return -1 or some other single value.

I always tested the return of getrows() with IsArray, and to make the rest of my code work right I converted the return value to an array so I could just pass along getrows() output to downstream code without having to test later on in the code.

oh man, I should be setting the row count to "", not the array.
Thanks Huw

you have to check for an array because that is what you are being given, getRows returns an array
cripto9t Posted - 11 March 2011 : 15:26:48
Nope it's been awhile. I just found that out in my search.
I still have to check for an array. I thought maybe they were connected.

do you have an include file that defines what adGetRowsRest is supposed to be ?
