Question

我正在尝试使用VBA在Microsoft Excel中查询表。我已经写了一些代码来尝试完成这个任务，但是我一直得到一个运行时错误'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，所以我可以查询这个表。

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

数据库：

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搜索找到了此Stack Overflow问题。看起来没有人试过回答它，所以这就是我最终做的事情。不要使用“QueryTable”，而是使用ADO命令对象，如this MSDN article中所做。

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()

使用VBA使用参数化查询在Excel中查询SQL Server
