使用Excel VBA运行SQL查询

I am fairly new to SQL and VBA. I have written a SQL query that I would like to be able to call and run from a VBA sub in an excel workbook and then bring the query results into the workbook. I have found some subs online (* and other places) that claim to do this but I am having trouble understanding them as they contain no explanation. For example, here is a sub that I found online:

我对SQL和VBA很陌生。我编写了一个SQL查询，我希望能够在excel工作簿中调用并运行VBA sub，然后将查询结果带入工作簿。我在网上找到了一些声称要这么做的潜艇(*和其他地方)，但我无法理解它们，因为它们没有任何解释。例如，我在网上找到了一个sub:

Sub ConnectSqlServer()

    Dim conn As ADODB.Connection
    Dim rs As ADODB.Recordset
    Dim sConnString As String

    ' Create the connection string.
    sConnString = "Provider=SQLOLEDB;Data Source=INSTANCE\SQLEXPRESS;" & _
                  "Initial Catalog=MyDatabaseName;" & _
                  "Integrated Security=SSPI;"

    ' Create the Connection and Recordset objects.
    Set conn = New ADODB.Connection
    Set rs = New ADODB.Recordset

    ' Open the connection and execute.
    conn.Open sConnString
    Set rs = conn.Execute("SELECT * FROM Table1;")

    ' Check we have data.
    If Not rs.EOF Then
        ' Transfer result.
        Sheets(1).Range("A1").CopyFromRecordset rs
    ' Close the recordset
        rs.Close
    Else
        MsgBox "Error: No records returned.", vbCritical
    End If

    ' Clean up
    If CBool(conn.State And adStateOpen) Then conn.Close
    Set conn = Nothing
    Set rs = Nothing

End Sub

First of all, would this work? Second, what do I need to replace in the sub (it looks like provider, data source, initial catalog, etc) and where do I find the info to replace them with?

首先，这行得通吗?第二，我需要在子目录中替换什么(它看起来像提供者、数据源、初始目录等)，我在哪里找到要替换它们的信息?

I hope this question is not too confusing and I appreciate your help!

我希望这个问题不要太让人迷惑，谢谢你的帮助!

Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):

下面是我目前用于将数据从MS SQL Server 2008提取到VBA中的代码。您需要确保有适当的ADODB引用[VBA编辑器->工具->引用]，并确保检查了Microsoft ActiveX数据对象2.8库，这是检查的倒数第二行(我在Windows 7上使用Excel 2010;你可能有一个稍微不同的ActiveX版本，但它仍将以微软ActiveX开始):

Dim rst As New ADODB.Recordset
Dim ConnectionString As String
Dim StrQuery As String

    'Opens connection to the database
    cnn.Open ConnectionString
    'Timeout error in seconds for executing the entire query; this will run for 15 minutes before VBA timesout, but your database might timeout before this value
    cnn.CommandTimeout = 900

    'This is your actual MS SQL query that you need to run; you should check this query first using a more robust SQL editor (such as HeidiSQL) to ensure your query is valid
    StrQuery = "SELECT TOP 10 * FROM tbl_table"

    'Performs the actual query
    rst.Open StrQuery, cnn
    'Dumps all the results from the StrQuery into cell A2 of the first sheet in the active workbook
    Sheets(1).Range("A2").CopyFromRecordset rst
