我在某些表上有一些触发器,在删除或更新某些内容时执行某个功能.在事务期间,如果触发器执行并且稍后在事务中它被回滚,那么触发器是否也会被回滚？

我是Java/Tomcat开发的新手,我看到这个问题,我的tomcat-users.xml文件一直在重置.我的用户一直被删除,我不知道为什么.我正在从Eclipse中启动我的应用程序,该应用程序正在部署到此Tomcat实例.

C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0

VM参数

-Dcatalina.base="C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0" -Dcatalina.home="C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0" -Dwtp.deploy="C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\wtpwebapps" -Djava.endorsed.dirs="C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\endorsed"

如何使用此自定义绑定禁用和启用锚标记.它适用于输入元素,但是锚标记只是改变了CSS,而不是禁用.

<a href="link" data-bind="myDisabled: !enabled()"/>

ko.bindingHandlers.myDisabled = {
    update: function(element, valueAccessor) {
        var value = ko.utils.unwrapObservable(valueAccessor());
        ko.bindingHandlers.css.update(element, function() {return { disabled: value }; });
        ko.bindingHandlers.disable.update(element, valueAccessor);
    }
};

我只是无法使用Spring Web Services弄清楚这个错误.我相信我做的一切都正确.

我正在使用下面的代码片段动态地订购我的Linq查询并且效果很好.我在反射或复杂的linq查询方面不是很出色,但我需要一种方法,当使用升序时,NULL值是最后一个,反之亦然.

因此,如果我的属性名称是一个整数且列值为1,3,5,那么所有NULL行都将在结尾处,而不是默认情况下的开头.我可以添加什么来表达这种情况？

此代码适用于实体框架,仍然需要进行NULL比较.

我有一个使用相同System.Runtime.Serialization.Primitives.dll程序集的控制台应用程序和网站.但是,当我运行网站时,我的程序集是右边的那个,但是如果我运行安慰应用程序,网站的DLL会转到左边的那个并导致错误.这两个项目都是v4.7,这是在我将所有项目升级到该框架后开始的.

两个项目都有这个

JSON.NET框架可以将XML转换为JSON,但它使用JSON中的@符号作为属性.我希望在将它发送到视图之前删除它.对此最好的方法是什么？

我知道我可以直接替换,但@字符在某处可能是相关的,不应该被替换.这有正则表达式吗？

public ActionResult Layout()
{
    var xml = new XmlDocument();
    xml.XmlResolver = null;
    xml.Load(Server.MapPath("~/App_Data/Navigation.xml"));
    return Content(JsonConvert.SerializeXmlNode(xml, Newtonsoft.Json.Formatting.Indented));
}

{
  "Layout": {
    "Navigation": [
      {
        "@Type": "Menu",
        "@Title": "Dashboard"
      },
      {
        "@Type": "Menu",
        "@Route": "Events",
        "@Title": "Events",
        "Navigation": {
          "@Type": "Action",
          "@Route": "Event",
          "@Title": "+ Add Event",
          "@Order": "1",
          "Navigation": {
            "@Type": "Item",
            "@Route": "Event",
            "@Name": "Event",
            "Navigation": [
              {
                "@Route": "Pools",
                "@Type": "SubNavigation",
                "@Name": "Pools"
              },
              {
                "@Route": "Brackets",
                "@Type": "SubNavigation",
                "@Name": "Brackets"
              }
            ]
          }

DROP TEMPORARY TABLE IF EXISTS data;即使我在顶部检查,我是否需要在存储过程结束时添加？是否存在性能影响？

CREATE DEFINER=`TEST`@`%` PROCEDURE `TEST`() BEGIN

    DROP TEMPORARY TABLE IF EXISTS data;

    CREATE TEMPORARY TABLE data AS 
...


END;

是否有键盘快捷方式或快速方法将以下代码更改为Visual Studio 2013中的单行？我也安装了Resharper.

多

new XElement("Option",
            new XAttribute("Name", "FileDelete"),
            "1"
        ),

单

new XElement("Option", new XAttribute("Name", "FileDelete"),"1" ),

当我的应用加载有任何引起关注的问题时,是否有以下消息.如果我残疾FirebaseAutomaticScreenReportingEnabled,那有什么后果吗？关于这个在线信息不多.
