Question

我在Excel VBA中有一个Access DataBase和一个表单。我输入数据库的所有数据都是通过VBA表格输入的。

此数据库包含我们今年在公司收到的所有福利卡。但是同一个员工可以要求两次或两次以上的卡，所以我们在DB上会有多个记录供他使用。

我需要的是当记录数大于1时，SQL语句结果应出现在Excel报告中。

我使用SELECT (*) COUNT语句来了解何时有多条记录与搜索条件兼容。但我不能使结果出现在Excel文件中。

这是我的代码：

Public Function Relatorio()
    Dim sql As String
    Dim cn  As ADODB.Connection
    Dim rs  As ADODB.Recordset
    Dim rel As String

    Set cn = New ADODB.Connection
    cn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & enderecoDB & ";Jet OLEDB:Database"
    cn.Open
    Set rs = New ADODB.Recordset
    sql = "INSERT INTO OPENROWSET('Microsoft.ACE.OLEDB.12.0', 'Excel 12.0;Database=" & enderecoDB & ";', 'SELECT * FROM [Planilha1$]') SELECT * FROM controle WHERE BP = " & controlectform.nmbpbox.Value & ";"
    rs.Open sql, cn
End Function

当我运行此代码时，它会给我一条消息，上面写着：

找不到OPENROWSET表退出

我无法安装新程序，因此我只需使用Excel VBA和Access DB即可。

我该如何做到这一点？

Answer 1

我不认为Access支持您正在使用的OPENROWSET动态表。我有很多旧的项目，但这是我的方法

Public Function Relatorio()

    Dim sql As String
    Dim cn  As ADODB.Connection
    Dim rs  As ADODB.Recordset
    Dim rel As String


    Set cn = New ADODB.Connection

    cn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & enderecoDB & ";Jet OLEDB:Database"

    cn.Open

    Set rs = New ADODB.Recordset

    dim path_To_XLSX
    dim name_of_sheet
    path_To_XLSX = "c:\temp\output.xlsx"
    name_of_sheet = "Planilha1"
    sql = sql = "SELECT * INTO [Excel 12.0;Database=" & path_To_XLSX & "]." & name_of_sheet & " FROM controle WHERE BP = '" & controlectform.nmbpbox.Value & "';" 

    rs.Open sql, cn

    'If this application is in an unsecure environment, use the following code instead!  This is to prevent a SQL injection, security concern here.
    'As it is an Access Database, this is likely overkill for this project
    'Create Command Object.
    Set Cmd1 = New ADODB.Command
    Cmd1.ActiveConnection = cn
    cmd1.CommandText = "SELECT * FROM controle INTO [Excel 12.0;Database=" & path_To_XLSX & "]." & name_of_sheet & " WHERE BP = ?"
    ' Create Parameter Object.
    Set Param1 = Cmd1.CreateParameter(, adInteger, adParamInput, 5) 'use adVarchar for strings(versus adInteger), https://www.w3schools.com/asp/met_comm_createparameter.asp
    Param1.Value = controlectform.nmbpbox.Value
    Cmd1.Parameters.Append Param1
    Set Param1 = Nothing
    Set Rs = Cmd1.Execute()

End Function

这么多年以前我遇到了这个挑战，但是我记不起了这个链接。检查它是否有帮助。

尝试{connw.Open（）; OleDbCommand命令; command = new OleDbCommand（＆＃34; Update Deliveries＆＃34; +＆＃34; SET Deliveries.EmployeeID = ?, Deliveries.FIN = ?, Deliveries.TodaysOrders =？，connw）; command.Parameters.Add（new OleDbParameter（＆＃34; @ EMPID＆＃34;，Convert.ToDecimal（empsplitIt [1]）））; command.Parameters.Add（new OleDbParameter（＆＃34; @ FIN＆＃34;，truckSplit [1] .ToString（）））; command.Parameters.Add（new OleDbParameter（＆＃34; @ TodaysOrder＆＃34;，＆＃34; R＆＃34;））; catchReturnedRows = command.ExecuteNonQuery（）; // Commit connw.Close（）; } catch（OleDbException异常）{MessageBox.Show（exception.Message，＆＃34; OleDb Exception＆＃34;）; }

Answer 3

您可以使用它来打印实际的SQL。

Private Sub Command2_Click()

Dim db As Database
Dim qr As QueryDef

Set db = CurrentDb

For Each qr In db.QueryDefs
  TextOut (qr.Name)
  TextOut (qr.SQL)
  TextOut (String(100, "-"))
Next

End Sub

Public Sub TextOut(OutputString As String)

    Dim fh As Long

    fh = FreeFile
    Open "C:\Users\rs17746\Desktop\Text_Files\sample.txt" For Append As fh
    Print #fh, OutputString
    Close fh

End Sub

这是您的另一个版本。这会将每个查询的结果导出到一个单独的文本文件中。

Private Sub Command0_Click()


Dim qdf As QueryDef
Dim strFileName As String
For Each qdf In CurrentDb.QueryDefs
If Left(qdf.Name, 1) <> "~" Then

'you need to figure out TransferText command. Maybe
'you won't be lazy and expect people to read it to
'you and tutor you on how it works.
strFileName = qdf.Name

'Docmd.TransferText ....
DoCmd.TransferText transferType:=acExportDelim, TableName:=strFileName, FileName:="C:\test\" & strFileName & ".txt", hasfieldnames:=True

End If
Next qdf
MsgBox "Done"


End Sub
