问题描述
我在 Access 2010 中使用 Microsoft SQL Server 2008 后端.我有一个将新值(由参数提供)插入表中的存储过程.分配给参数的值是从文件夹中存储的文件中获取的.Windows 文件系统用于扫描特定文件夹以制作其中的文件列表.对于每个扫描的文件，调用存储过程，并使用 FileName 和 QueueId(不带扩展名的文件名)以及其他值作为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.
I am working in Access 2010 with a Microsoft SQL Server 2008 backend. I have a stored procedure that inserts new values(supplied by the parameters) into a table. The values assigned to the parameters are obtained from files stored in a folder. The Windows File System is used to scan a particular folder to make a list of the files in it. For each scanned file the stored procedure is called and the FileName and QueueId (Filename without extension) along with other values are used as parameters for the stored procedure called. The stored procedure is used to create new records for each file for a table.
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
和存储过程是:
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
所有的例子都没有给我一个创建连接和调用过程的可靠想法.我得到的一些建议是研究 ExecuteNonquery 的工作原理，所以我一直在努力寻找与此相关的示例.以下是我找到的示例模板之一
All the examples haven't really given me a solid idea of to create the connection and call the procedure. Some advice I have been given is to study how ExecuteNonquery works so I have been trying to find examples related to that. The following is one of the example templates I've found
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
我不太确定我应该从这个例子中得到什么以及如何合并传递值.此外，即使我访问了 http://www.connectionstrings.com/ 我仍然对如何制作感到困惑他们.任何帮助将不胜感激
I am not really sure what I should take from this example and how to incorporate passing values. Also even though I have visited http://www.connectionstrings.com/ I am still confused on how to make them. Any help would be greatly appreciated
推荐答案
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", adVarChar, adParamInput, 60, "value for InstrumentName")
'...
cmd.Execute
conn.Close
