Я создаю календарь расписания, который работал отлично, но я хочу настроить SQL так, чтобы он отображался только тогда, когда нужно выполнить следующую работу. Я думал, что лучший способ добиться этого - использовать функцию MAX (), однако, когда я запускаю код, Access, похоже, не нравится.
Public Sub LoadArray()
'This sub loads an array with the relevant variables from a query
Dim db As Database
Dim rs As Recordset
Dim rsFiltered As Recordset
Dim strQuery As String
Dim i As Integer
Dim Text23 As Integer
On Error GoTo ErrorHandler
Text23 = Forms.frmPreventativeMenu.Form.CompanyName.Value
strQuery = "SELECT tblWMYReports.Company, tblWMYReports.Machine, MAX(tblWMYReports.NextDate), tblWMYReports.WMY " _
& "FROM tblWMYReports " _
& "WHERE (((tblWMYReports.Company)= " & Text23 & " ));"
Set db = CurrentDb
Set rs = db.OpenRecordset(strQuery)
With rs
If Not rs.BOF And Not rs.EOF Then
'Ensures the recordset contains records
For i = 0 To UBound(MyArray)
'Will loop through the array and use dates to filter down the query
'It firsts checks that the second column has true for its visible property
If MyArray(i, 1) = True Then
.Filter = "[NextDate]=" & MyArray(i, 0)
'To filter you must open a secondary recordset and
'Use that as the basis for a query
'This makes sense as you are building a query on a query
Set rsFiltered = .OpenRecordset
If Not rsFiltered.BOF And Not rsFiltered.EOF Then
'If the recordset is not empty then you are able
'to extract the text from the values provided
Do While Not rsFiltered.EOF = True
MyArray(i, 2) = MyArray(i, 2) & vbNewLine & DLookup("MachineName", "tblMachine", "MachineID=" & rsFiltered!Machine)
MyArray(i, 2) = MyArray(i, 2) & " - " & DLookup("WMY", "tblWMY", "ID=" & rsFiltered!WMY)
rsFiltered.MoveNext
Loop
End If
End If
Next i
End If
.Close
End With
ExitSub:
Set db = Nothing
Set rs = Nothing
