Good day,

Iam traying to get result of my record as below

If next record is biger than previous show "1"
If next record is same previous show "1"
If next record is smallest show "0"
if next record is same previous show "0"

Example

id	Time		Code	Price	Res
   1	10:00:00 AM	1010	905     0
 464	10:00:34 AM	1010	906     1
 626	10:00:56 AM	1010	906	1
1523	10:02:16 AM	1010	904	0
1568	10:02:21 AM	1010	904	0
1569	10:02:21 AM	1010	905	1

the code gave me correct result for some filed and other incorrect !

Could you please check the code and correct it for me.

I have attached the DB for any correction

Note: the command bottons on Form1 of Forms Object.

the vb code:


Private Sub cmdUpdate_Click()
Dim cnn As ADODB.Connection
Dim rst As New ADODB.Recordset
Dim SQL As String
Dim Code As String
Dim Price As Long
'Dim Res As String
Dim Res As Variant
'Dim PrevRes As String
Dim PrevRes As Variant

Set cnn = CurrentProject.Connection
SQL = "Select [Code],[Price],[Res] from [tt]" & _
" order by [Code],[ID]"

rst.Open SQL, cnn, adOpenKeyset, adLockOptimistic

Do While Not rst.EOF
Code = rst![Code]
Price = rst![Price]
'PrevRes = ""
PrevRes = Null
rst.MoveNext
Do While rst![Code] = Code
'Res = IIf(rst![Price] > [Price], "1", IIf(rst![Price] < [Price], "0", IIf(rst![Price] = [Price], PrevRes, Null)))
Res = IIf(rst![Price] > [Price], "1", IIf(rst![Price] < [Price], "0", PrevRes))
rst![Res] = Res
PrevRes = Res
Price = rst![Price]
rst.MoveNext
If rst.EOF Then
Exit Do
End If
Loop
Loop
Set cnn = Nothing
Set rst = Nothing

MsgBox "Res field updated."

End Sub

thanks for assistant . :)

Iam sorry my expamle was not cleared.

Asum that I have this fields: Id,Code,Price,Res

the "res" field will show the vb code result

if the current price = 905 then I input a new entery with price 905 the Res filed should show "0" because the price same as previous price. Then when I input a new entry with price 906 the result should show "1" because the previos record is less.
