[HttpPost]
public void InsertOrUpdateDirector(Director director)
{
    int idReturned = 0;

    string query = null;
    myConnection.Open();
    if (director.Operation == 'I')
    {
      query = "INSERT...";
    }
    else if (director.Operation == 'U')
    {
      query = "UPDATE ...";
    }
    var cmd = new SqlCommand(query, myConnection);
    cmd.ExecuteNonQuery();
    myConnection.Close();

    idReturned = "???";

    return idReturned;
}

我只是想在insert语句之后返回新创建的ID.我该怎么做呢？

基本上,如果参数以NULL形式出现,我想将其作为数据库NULL发送到数据库.因此(查看下面代码中的注释):

[HttpPost]
    public void UpdateTitle(Title title)
    {
      string query = null;
      string description = "";
      string episodeAKA = "";

      if (title.Description != null)
      {
        description = "'" + title.Description + "'";
      }
      else
      {
        //here's where description should be a DBNULL. 
      }

      if (title.EpisodeAKA == null)
      {
        title.EpisodeAKA = "NULL";
      }

      myConnection.Open();
      if (title.Operation == 'U')
      {
        query = "UPDATE dbo.AWD_Titles SET AwardStatusId = " + title.AwardStatus + ", Description = " + description + ", IsVerified = " + …

如何从大量丑陋的字符串中提取特定字符串的PART？

串:

https://company.zendesk.com/api/v2/tickets/33126.json

我需要33126号.

提取这个数字的最佳方法是什么？

请参阅以下代码中的评论:

$('#btnDelete').on('click', function()
{
    var treeView = $("#treeview").data("kendoTreeView");
    var userId = $('#user_id').val();

    $('#treeview').find('input:checkbox:checked').each(function()
    {
        debugger;

        var li = $(this).closest(".k-item")[0];
        var notificationId = treeView.dataSource.getByUid(li.getAttribute('data-uid')).ID;

        if (notificationId == undefined)
        {
              //if the notification ID is "undefined" here, I want the ".EACH" 'loop' to continue to the next item.
        }
        $.ajax(
            {
                url: '../api/notifications/deleteNotification?userId=' + userId + '&notificationId=' + notificationId,
                type: 'DELETE'
            }).done(function()
            {
                var treeview = $("#treeview").data("kendoTreeView");
                treeview.destroy();
                CreateNotificationTree(userId);
                console.log('Delete successful.');
            }).fail(function(jqXHR, status, error)
            {
                console.log("Error : " + error);
            });
        treeView.remove($(this).closest('.k-item')); …

这不起作用:

DBCC CHECKIDENT('[DMS].[dbo].[ImportedFiles]', RESEED, 0)

插入下一条记录后,我希望种子为0而不是1.

我试过这个,但功能不喜欢它:

DBCC CHECKIDENT('[DMS].[dbo].[ImportedFiles]', RESEED, -1)

DBCC CHECKIDENT('[DMS].[dbo].[ImportedFiles]', RESEED, '-1')

如何重置表的种子,以便下一个记录是零？(0)？
