Querying a SQL Server in Excel with a parameterized query using VBA
提问by Mitchell Walker
I'm trying to query a table in Microsoft Excel using VBA. I've written up some code to try and accomplish this task, but I keep getting a run-time error '1004' saying it's a General ODBC error. I'm not sure what I need to do to get this code to run properly so I can query this table.
我正在尝试使用 VBA 在 Microsoft Excel 中查询表。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”，说这是一个常规 ODBC 错误。我不确定我需要做什么才能让这段代码正常运行，这样我才能查询这个表。
I'm using SQL Server Express, the server I'm connecting to: .\SQLEXPRESS
我正在使用 SQL Server Express，我要连接到的服务器： .\SQLEXPRESS

I found this Stack Overflow question with a Google search. It does not look like anyone has tried answering it, so here's what I ended up doing. Instead of using "QueryTable", use an ADO command object as done in this MSDN article.
我通过 Google 搜索发现了这个 Stack Overflow 问题。看起来没有人尝试过回答它，所以这就是我最终要做的。使用 ADO 命令对象，而不是使用“QueryTable”，就像这篇 MSDN 文章中所做的那样。
MSDN Example:
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()
