如何跟踪在批量更新中失败的行更新 [英] How to track which row update failed in batch update

问题描述

我正在使用try catch块使用ADO.NET2.0进行批处理更新，UpdateBatchSize设置为500，我经常可以捕获异常，但是我不知道哪个行更新失败，有没有办法以获得实际的失败行？

I'm using a try catch blocks to do a batch update using ADO.NET2.0, the UpdateBatchSize is set 500, I can often catch exceptions, but I don't know which row update failed, is there a way to get the actual failed row?

推荐答案

您可以使用事件 RowUpdated 获取行的引用：

You can use event RowUpdated to get the reference of row:

yourAdapter.RowUpdated += OnRowUpdated;

然后：

protected static void OnRowUpdated(object sender, SqlRowUpdatedEventArgs args)
{
    if (args.Status == UpdateStatus.ErrorsOccurred)
    {
        // Reference to row which throws error
        var row = args.Row;

        row.RowError = args.Errors.Message;
        args.Status = UpdateStatus.SkipCurrentRow;

        // Do something more
    }
}
