sql-server - 使用 VBA 通过参数化查询在 Excel 中查询 SQL Server

Question

我正在尝试使用 VBA 查询 Microsoft Excel 中的表。我已经编写了一些代码来尝试完成此任务，但我不断收到运行时错误“1004”，指出这是常规 ODBC 错误。我不确定需要做什么才能使该代码正常运行，以便我可以查询该表。

我正在使用 SQL Server Express，我正在连接到的服务器:.\SQLEXPRESS

数据库:

Databaselink

查询产品表VBA代码:

Sub ParameterQueryExample()
'---creates a ListObject-QueryTable on Sheet1 that uses the value in 
'        Cell Z1 as the ProductID Parameter for an SQL Query
'        Once created, the query will refresh upon changes to Z1. 

Dim sSQL As String
Dim qt As QueryTable
Dim rDest As Range


'--build connection string-must use ODBC to allow parameters
Const sConnect = "ODBC;" & _
    "Driver={SQL Server Native Client 10.0};" & _
    "Server=.\SQLEXPRESS;" & _
    "Database=TSQL2012;" & _
    "Trusted_Connection=yes"


'--build SQL statement
sSQL = "SELECT *" & _
        " FROM TSQL2012.Production.Products Products" & _
        " WHERE Products.productid = ?;"


'--create ListObject and get QueryTable
Set rDest = Sheets("Sheet1").Range("A1")
rDest.CurrentRegion.Clear  'optional- delete existing table


Set qt = rDest.Parent.ListObjects.Add(SourceType:=xlSrcExternal, _
    Source:=Array(sConnect), Destination:=rDest).QueryTable


'--add Parameter to QueryTable-use Cell Z1 as parameter
With qt.Parameters.Add("ProductID", xlParamTypeVarChar)
    .SetParam xlRange, Sheets("Sheet1").Range("Z1")
    .RefreshOnChange = True
End With


'--populate QueryTable
With qt
    .CommandText = sSQL
    .CommandType = xlCmdSql
    .AdjustColumnWidth = True  'add any other table properties here
    .BackgroundQuery = False
    .Refresh
End With


Set qt = Nothing
Set rDest = Nothing
End Sub

我通过 Google 搜索发现了这个 Stack Overflow 问题。看起来没有人尝试回答这个问题，所以这就是我最终所做的。不要使用“QueryTable”，而是使用 ADO 命令对象，如 this MSDN article 中所做的那样。 .

MSDN 示例:

Dim Conn1 As ADODB.Connection
Dim Cmd1 As ADODB.Command
Dim Param1 As ADODB.Parameter
Dim Rs1 As ADODB.Recordset

Dim i As Integer

' Trap any error/exception.
On Error Resume Next

' Create and Open Connection Object.
Set Conn1 = New ADODB.Connection
Conn1.ConnectionString = "DSN=Biblio;UID=admin;PWD=;"
Conn1.Open

' Create Command Object.
Set Cmd1 = New ADODB.Command
Cmd1.ActiveConnection = Conn1
Cmd1.CommandText = "SELECT * FROM Authors WHERE AU_ID < ?"

' Create Parameter Object.
Set Param1 = Cmd1.CreateParameter(, adInteger, adParamInput, 5)
Param1.Value = 5
Cmd1.Parameters.Append Param1
Set Param1 = Nothing

' Open Recordset Object.
Set Rs1 = Cmd1.Execute()
