我在Access 2010中使用Microsoft sql Server 2008后端.我有一个存储过程将新值(由参数提供)插入表中.分配给参数的值是从存储在文件夹中的文件中获取的. Windows文件系统用于扫描特定文件夹以生成其中的文件列表.对于每个扫描的文件,调用存储过程,并将FileName和QueueId(没有扩展名的文件名)以及其他值用作调用的存储过程的参数.存储过程用于为表的每个文件创建新记录.
Public Function CreateInstrumentInterfaceLogRecords(BatchID As Long,InstrumentName As String) As Boolean On Error GoTo HandleError Dim objFSO As FileSystemObject Dim AllFiles As Object Dim objFolder As Object Dim objFile As Object Dim FileExt As String Dim strsql As String CreateInstrumentInterfaceLogRecords = False strsql = "SELECT FileExt FROM tlkpInstrument" FileExt = ExecuteScalar(strsql) Set objFSO = CreateObject("Scripting.FileSystemObject") Set objFolder = objFSO.GetFolder(NewPath) 'NewPath is a public variable that holds the path to the folder' Set AllFiles = objFolder.Files For Each objFile In AllFiles FileName = objFile.FileName QuenueId = Replace(FileName,FileExt,"") 'call procedure to pass values' Next objFile ExitProc: Exit Function HandleError: MsgBox Err.Number & " " & Err.Description & " in CreateInstrumentInterfaceLogRecords" GoTo ExitProc End Function
并且存储过程是:
CREATE PROCEDURE upInsertToInstrumentInterfaceLog @BatchID nvarchar(60),@InstrumentName nvarchar(60),@FIleName nvarchar(60),@QueueId nvarchar(60) AS INSERT INTO tblInstrumentInterfaceLog (BatchID,InstrumentName,FileName,QueueID,DateOfBatch,Folder) VALUES (@BatchID,@InstrumentName,@FileName,@QueueId,getdate(),'New'); GO
所有这些例子都没有给我一个创建连接和调用过程的可靠想法.我给出的一些建议是研究ExecuteNonquery如何工作,所以我一直试图找到与此相关的例子.以下是我发现的示例模板之一
Dim conn As ADODB.Connection Dim cmd As ADODB.Command Set conn = New ADODB.Connection conn.ConnectionString = “your connection String here” conn.Open Set cmd = New ADODB.Command cmd.ActiveConnection = conn cmd.CommandType = adCmdStoredProc cmd.CommandText = "put stored procedure name here" cmd.Execute conn.Close Set conn = Nothing Set cmd = Nothing
我不确定从这个例子中应该采取什么以及如何合并传递值.即使我已经访问了http://www.connectionstrings.com/,我仍然对如何制作它们感到困惑.任何帮助将不胜感激
解决方法
Dim conn As ADODB.Connection Dim cmd As ADODB.Command Set conn = New ADODB.Connection conn.ConnectionString = “your connection String here” conn.Open Set cmd = New ADODB.Command cmd.ActiveConnection = conn cmd.CommandType = adCmdStoredProc cmd.CommandText = "upInsertToInstrumentInterfaceLog" cmd.parameters.Append cmd.CreateParameter("@BatchID",adVarChar,adParamInput,60,"value for BatchID") cmd.parameters.Append cmd.CreateParameter("@InstrumentName","value for InstrumentName") '... cmd.Execute conn.Close
