I'm trying to update one field (tblUSA.RunSum) with the running sum of another field (Length), starting at tblUSA.RunSum= 0 for the first value. So far, I'm having no luck. Mo updates tblUSA are writing.
Dim db As Database
Set db = CurrentDb()
Dim lastValue, thisValue
s = "tblUSA"
Set rs = db.OpenRecordset(s, dbOpenDynaset)
'rs.Sort ("DateS")
lastValue = rs.Fields("Length")
rs.MoveNext
While (Not rs.EOF())
thisValue = rs.Fields("Length")
rs.Edit
rs!RunSum = thisValue + lastValue
rs.Update
lastValue = thisValue ' remember previous value
rs.MoveNext ' advance to next record
Wend
MsgBox "Done with " & s
This might do:
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim lastValue As Double
Dim s As String
Set db = CurrentDb()
s = "Select * From tblUSA Order By DateS"
Set rs = db.OpenRecordset(s, dbOpenDynaset)
While Not rs.EOF
rs.Edit
rs!RunSum.Value = lastValue ' Initially = 0
rs.Update
lastValue = lastValue + rs.Fields("Length").Value
rs.MoveNext
Wend
rs.Close

I'm following this tutorial to create a add/subtract button that amends the 'Qty_Avail' value of a Stock table
https://www.youtube.com/watch?v=88erYOa8cmg
Private Sub cmdIN_Click()
Dim db As DAO.Database
Dim rst As DAO.Recordset
Set db = CurrentDb
Set rst = db.OpenRecordset("Select Qty_Avail from Stock where ID_Item =' " & Me.ID_Item & " ' ")
With rst
.Edit
!Qty_Avail = !Qty_Avail + Nz(Me.Quantity, 0)
.Update
End With
Me.QOH.Requery
Me.Quantity = "'"
End Sub
Try using the RecordsetClone - faster and updates at once:
Private Sub cmdIN_Click()
Dim rst As DAO.Recordset
Set rst = Me.RecordsetClone
With rst
' Locate current record.
.Bookmark = Me.Bookmark
' Edit the record.
.Edit
!Qty_Avail.Value = !Qty_Avail.Value + Nz(Me!Quantity.Value, 0)
.Update
.Close
End With
Me!Quantity.Value = 0 ' Or = Null
End Sub
So I have this SQL Query
SELECT *
FROM [Employee To Manager]
WHERE [Employee To Manager].[Manager UID] In(getMyTeamUserNames());
Which has a VBA function getMyTeamUserNames()
Public Function getMyTeamUserNames() As String
Dim rs As DAO.Recordset
Dim dbs As DAO.Database
Set dbs = CurrentDb
getMyTeamUserNames = commaDelimitArray(getTeamUserNames(getUserName, dbs))
End Function
Public Function commaDelimitArray(arrayStr) As String
Dim sepStr As String
sepStr = "','"
commaDelimitArray = "'" & Join(arrayStr, sepStr)
End Function
Public Function getTeamUserNames(username, dbs) As String()
Dim sqlstatement As String
sqlstatement = "SELECT * FROM [Employee to Manager] WHERE [Employee to
Manager].[Manager UID] = '" & username & "'"
Set rs = dbs.OpenRecordset(sqlstatement, dbOpenSnapshot)
Dim ComputerUsernames() As String
Dim FindRecordCount As Integer
If rs.EOF Then
FindRecordCount = 0
Exit Function
Else
rs.MoveLast
FindRecordCount = rs.RecordCount
End If
ReDim ComputerUsernames(FindRecordCount) As String
Dim i As Integer
i = 0
rs.MoveFirst
Do Until rs.EOF = True
ComputerUsernames(i) = rs("Computer Username")
If (ComputerUsernames(i) <> "") Then
i = i + 1
End If
If (ComputerUsernames(i - 1) <> username) Then
Dim recurResult() As String
recurResult = getTeamUserNames(ComputerUsernames(i - 1), dbs)
Dim resultSize As Integer
If Len(Join(recurResult)) > 0 Then
resultSize = UBound(recurResult) - LBound(recurResult) + 1
ReDim Preserve ComputerUsernames(UBound(ComputerUsernames) + resultSize)
For Each resultStr In recurResult
ComputerUsernames(i) = resultStr
If (ComputerUsernames(i) <> "") Then
i = i + 1
End If
Next resultStr
End If
End If
rs.MoveNext
Loop
ReDim Preserve ComputerUsernames(i - 1)
getTeamUserNames = ComputerUsernames
End Function
Query runs and I get no data.
However if I take the result from getMyTeamUserNames() and put it in the query by hand it works. getMyTeamUserNames() result varies from possibly 2 results to 40 (recursively gets subordinates all the way down the tree).
So a C Perkins specifically pointed out this would never work so I have rebuilt the query with some other queries.
'Below is the current code that I have and it will export to the excel workbook and worksheet correctly. The only problem is that I need to limit the data that gets exported by a month end date range (example: 1/31/2017 to 4/30/2017) and also by a plant number (example: "4101") thanks for any help it is greatly appreciated.

You can use:
Dim Date1 As Date
Dim Date2 As Date
Dim PlantNr As String
Dim Sql As String
Date1 = #1/31/2017#
Date2 = #4/30/2017#
PlantNr = "4101"
Sql = "Select * From [(QS)_Inventory] Where YourDateField Between #" & Format(Date1, "yyyy\/mm\/dd") & "# And #" & Format(Date2, "yyyy\/mm\/dd") & "# And [Plant Number] = '" & PlantNr & "'"
Set rs = CurrentDb.OpenRecordset(Sql)
My code is generating an Invalid Use Of Null and I am not seeing the issue. When I compile the code, I do not get an error, but when I run and debug it, the error occurs at strRESMILE = rs("RESMILE").
Any thoughts? I can upload the database if need be.

Handle the evident NULL in your [RESMILE] field by using Nz().
So change strRESMILE = rs("RESMILE") to strRESMILE = Nz(rs("RESMILE"))
I am unable to get the count of records by openining Ms Access Query, I use the following code.
Private Sub CmdGetData_Click()
Dim WRK As Workspace
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim StrSql As String
Set WRK = DBEngine.Workspaces(0)
Set db = CurrentDb
StrSql = "select * from [QrySalePatti]"
Set rs = db.OpenRecordset(StrSql, dbOpenDynaset)
Do While (Not rs.EOF)
rs.MoveFirst
rs.MoveLast
MsgBox rs.RecordCount
Loop
exitRoutine:
If Not (db Is Nothing) Then
db.Close
Set db = Nothing
End If
Set WRK = Nothing
End Sub
You should not need a Do While loop to get the RecordCount.
Set rs = db.OpenRecordset(StrSql, dbOpenDynaset)
With rs
If Not (.BOF And .EOF) Then
.MoveLast
End If
MsgBox .RecordCount
End With
However if your goal is only to count the rows from QrySalePatti, you could use a SELECT Count(*) query and read the value returned from that.
StrSql = "SELECT Count(*) AS row_count FROM [QrySalePatti]"
Set rs = db.OpenRecordset(StrSql)
MsgBox rs!row_count
Or you could use a DCount expression.
MsgBox DCount("*", "QrySalePatti")
