Iis 7 使用ASP的Sqlbulkcopy在iis6中工作，但在iis7中失败

我能够让sqlbulkcopy在iis6（测试服务器）和iis7（实时服务器）上正常工作，但在iis7中上载数据时，行被切断。在iis7的250000个产品中，它只进口了190000个。在iis 6中，它使用相同的代码/页面加载所有250000条记录，没有问题。另外，两台服务器正在更新相同的SQL DB

我到处寻找解决办法。非常感谢您的帮助

    Sub UpdateData()

    Dim sSQLTable As String = "Table1"
    Dim sExcelFileName As String = savePath
    Dim sWorkbook() As String = GetExcelSheetNames(sExcelFileName)

    'Create our connection strings
    Dim sExcelConnectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & sExcelFileName & ";Extended Properties=""Excel 12.0;HDR=YES;"""

    'Execute a query to erase any previous data from our destination table
    Dim sClearSQL = "DELETE FROM " & sSQLTable
    Dim SqlConn As SqlConnection = New SqlConnection(ConnString)
    Dim SqlCmd As SqlCommand = New SqlCommand(sClearSQL, SqlConn)
    SqlConn.Open()
    SqlCmd.ExecuteNonQuery()
    SqlConn.Close()

    'Series of commands to bulk copy data from the excel file into our SQL table
    Dim OleDbConn As OleDbConnection = New OleDbConnection(sExcelConnectionString)
    OleDbConn.Open()

    Dim OleDbCmd As OleDbCommand = New OleDbCommand(("SELECT * FROM [" & sWorkbook(0) & "]"), OleDbConn)
    Dim dr As OleDbDataReader = OleDbCmd.ExecuteReader()
    Dim bulkCopy As SqlBulkCopy = New SqlBulkCopy(ConnString, SqlBulkCopyOptions.UseInternalTransaction)
    bulkCopy.BulkCopyTimeout = 2000
    bulkCopy.DestinationTableName = sSQLTable
    'DEMO bulkCopy.ColumnMappings.Add("Excel", "SQL")
    bulkCopy.ColumnMappings.Add("Material", "Material")
    bulkCopy.ColumnMappings.Add("Plnt", "Plant")
    bulkCopy.ColumnMappings.Add("SLoc", "SLoc")
    bulkCopy.ColumnMappings.Add("S", "S")
    bulkCopy.ColumnMappings.Add("Batch", "Batch")
    bulkCopy.ColumnMappings.Add("Special Stock Number", "SpecialStockNumber")
    bulkCopy.ColumnMappings.Add("Material Description", "MatDesc")
    bulkCopy.ColumnMappings.Add("Typ", "Type")
    bulkCopy.ColumnMappings.Add("StorageBin", "StorageBin")
    bulkCopy.ColumnMappings.Add("Available stock", "AvailStock")
    bulkCopy.ColumnMappings.Add("BUn", "BUn")
    'bulkCopy.ColumnMappings.Add("GR Date", "GRDate")
    bulkCopy.WriteToServer(dr)
    OleDbConn.Close()
End Sub

感谢Andy提供的ExcelDataReader提示

让它一起工作。看起来这是OleDB的内存问题。发布我的代码，以防将来对其他人有所帮助

    Dim SqlCmd As SqlCommand = New SqlCommand(sClearSQL, SqlConn)
    SqlConn.Open()
    SqlCmd.ExecuteNonQuery()
    SqlConn.Close()


    Dim stream As FileStream = File.Open(savePath, FileMode.Open, FileAccess.Read)

你有例外吗？活动服务器是否离得更远（可能与超时有关）？事件查看器中是否有任何相关内容？数据库位于实时服务器上。一模一样。我也没有错误。它只是在某个记录计数处运行和停止。我在两个测试中使用相同的excel文件。您提到IIS7框在大约190000行之后停止。IIS7服务器上的确切行数总是相同的，还是在运行期间有所不同？iis6在我的XP笔记本电脑上。IIS7在win2008 64位服务器上。两者都有相同版本的Office。但是我必须安装32位的MADE。在您的评论之后，我通过复制将数据粘贴到同一Office 2010版本的新Excel文件中，重新保存了该文件。现在它给了我一个不同的记录数，但接近190000条。我想可能是某种内存问题，但这是一个相对较小的文件。我的猜测是，在生产服务器上，数据读取器没有读取Excel文件中的所有行。我的建议是从等式中删除OleDb，并使用类似的方法。这将使用OpenXML而不是OleDb读取Excel文件。另外，这种方法不需要在web服务器上安装任何Office/ACE组件。
