Question

我正在尝试使用VBA从Excel运行存储过程，但是我遇到以下代码的“类型不匹配”错误。我可以执行带参数的存储过程作为传递给Command对象的字符串，如下所示吗？

Function Sproc()
    Dim cnn As New ADODB.Connection
    Dim rst As New ADODB.Recordset
    Dim cmd As ADODB.Command
    Dim ConnectionString As String
    Dim StrSproc As String

    ConnectionString = "Provider=SQLOLEDB;Data Source=DBSource;" & _
                  "Initial Catalog=CurrentDb;" & _
                  "Integrated Security=SSPI;"

    '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 times out, but your database might timeout before this value

    cnn.CommandTimeout = 900

    StrSproc = "EXEC StoredProcedure " & _
                    "@parameter1 = 0," & _
                    "@parameter2 = 0," & _
                    "@parameter3 = 0,"

        Application.StatusBar = "Running stored procedure..."
        Set rst = cmd.Execute(, , StrSproc)
End Function

Answer 1

试试这个：

Option Explicit

Function Sproc()
    Dim cnn As New ADODB.Connection
    Dim rst As New ADODB.Recordset
    Dim cmd As ADODB.Command
    Dim cnnStr As String
    Dim Rs As New ADODB.Recordset
    Dim StrSproc As String

    cnnStr = "Provider=SQLOLEDB;Data Source=DBSource;" & "Initial Catalog=CurrentDb;" & _
             "Integrated Security=SSPI;"
    With cnn
        .CommandTimeout = 900
        .ConnectionString = cnnStr
        .Open
    End With
    With cmd
        .ActiveConnection = cnn
        .CommandType = adCmdStoredProc
        .CommandText = "[StoredProcedureName]"
        .Parameters.Append .CreateParameter("@parameter1", adInteger, adParamInput, , 0)
        .Parameters.Append .CreateParameter("@parameter2", adInteger, adParamInput, , 0)
        .Parameters.Append .CreateParameter("@parameter2", adInteger, adParamInput, , 0)
    End With
    With Rs
        .CursorType = adOpenStatic
        .CursorLocation = adUseClient
        .LockType = adLockOptimistic
        .Open cmd
    End With
    Application.StatusBar = "Running stored procedure..."
    Set rst = cmd.Execute
End Function

这是我的首选方法：

Function Sproc()
    Dim cnn As ADODB.Connection
    Dim rst As ADODB.Recordset
    Dim cmd As ADODB.Command
    Dim ConnectionString As String
    Dim StrSproc As String

    Set cnn = New ADODB.Connection
    cnn.ConnectionString = "Provider=SQLOLEDB;Data Source=DBSource;" & _
                  "Initial Catalog=CurrentDb;" & _
                  "Integrated Security=SSPI;"

    'Opens connection to the database
    On Error GoTo SQL_ConnectionError
    cnn.Open ConnectionString
    On Error GoTo 0
    '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

    Set rst = New ADODB.Connection
    StrSproc = "set nocount on; "
    StrSproc = StrSproc & "EXEC StoredProcedure " & _
                        "@parameter1 = 0," & _
                        "@parameter2 = 0," & _
                        "@parameter3 = 0 "
    rst.ActiveConnection = cnn
    On Error GoTo SQL_StatementError
    rst.Open StrSproc
    On Error GoTo 0

    If Not rst.EOF And Not rst.BOF Then
        Sproc = IIF(IsNull(rst.Fields(0).Value), "(BLANK)", rst.Fields(0).Value)
    EndIf

    Exit Function

    SQL_ConnectionError:
    Msgbox "Error connecting to the server / database. Please check the connection string."
    Exit Function

    SQL_StatementError:
    Msgbox "Error with the SQL syntax. Please check StrSproc."
    Debug.Print StrSproc
    Exit Function

End Function
