Question

我有在互联网上获得的（最终）代码。这行代码在WHERE中给出了错误，因为它是文本：

strSQL = " SELECT [VENDAS$].[Data], [VENDAS$].[Vendedor], [VENDAS$].[Total]" & _
" FROM [VENDAS$] WHERE [VENDAS$].[Vendedor] = Murilo;"

用以下数字代替下面的数字不会引起错误：

strSQL = " SELECT [VENDAS$].[Data], [VENDAS$].[Vendedor], [VENDAS$].[Total]" & _
" FROM [VENDAS$] WHERE [VENDAS$].[Total] >= 100000;"

然后我问：您最后需要这个分号吗？

这是完整的代码，我还问：是否需要在代码末尾为变量conn，rst和fld设置Nothing？要运行完整代码，我需要添加一些库吗？

Sub RunSQL()
On Error GoTo ErrHandle
    Dim conn As Object, rst As Object
    Dim strConnection As String, strSQL As String
    Dim wkCaminho, wkArquivo As String
    Dim I As Integer
    Dim fld As Object

    Set conn = CreateObject("ADODB.Connection")
    Set rst = CreateObject("ADODB.Recordset")
    wkCaminho = ThisWorkbook.Path & "\"
    wkArquivo = "MATRIZ DE DADOS.xlsx"
    ActiveSheet.Cells.Delete
    ' Hard code database location and name
    strConnection = "Provider=Microsoft.ACE.OLEDB.12.0;" _
                       & "Data Source='" & wkCaminho & wkArquivo & "';" _
                       & "Extended Properties=""Excel 8.0;HDR=YES;"";"

'    strSQL = " SELECT [VENDAS$].[Data], [VENDAS$].[Vendedor], [VENDAS$].[Total]" & _
'    " FROM [VENDAS$] WHERE [VENDAS$].[Total] >= 100000;"

    strSQL = " SELECT [VENDAS$].[Data], [VENDAS$].[Vendedor], [VENDAS$].[Total]" & _
    " FROM [VENDAS$] WHERE [VENDAS$].[Vendedor] = Murilo;"

    ' Open the db connection
    conn.Open strConnection
    rst.Open strSQL, conn

    ' column headers
    I = 0
    Worksheets("Results").Range("A1").Activate
    For Each fld In rst.Fields
        ActiveCell.Offset(0, I) = fld.Name
        I = I + 1
    Next fld

    ' data rows
    Worksheets("Results").Range("A2").CopyFromRecordset rst

    rst.Close
    conn.Close

    MsgBox "Successfully ran SQL query!", vbInformation
    Exit Sub

ErrHandle:
    MsgBox Err.Number & " = " & Err.Description, vbCritical
    Exit Sub
End Sub

Answer 1

...WHERE [VENDAS$].[Vendedor] = Murilo;"

应该是

...WHERE [VENDAS$].[Vendedor] = 'Murilo'"

非数字字段需要在值两边加上引号。

我通常会省略分号-如果发现包含分号，我会发现它是一个问题，但在将其排除在外时我从未遇到任何问题。
