小编Sco*_*合理论的帖子

只是想知道是否可以在sql server 2005上为用户sa使用混合模式？我知道如何在管理工作室中这样做,但这对用户"sa"来说还不够.我认为还需要做其他事情.

我试图通过控制台应用程序连接到数据库,但不断收到错误"帐户被禁用"

干杯

我有这样的映射类:

[Table("MyTable")]
class MyClass         
{   
        //properties; id, name, etc...

        private string _queuedToWHTime = string.Empty;
        [Column("QueuedToWHTime")]
        public string QueuedToWHTime
        {
            get { return _queuedToWHTime; }
            set { _queuedToWHTime = value; }
        }

        public DateTime? QueuedToWHTime_DateTime
        {
            get
            {
                if (!string.IsNullOrWhiteSpace(_queuedToWHTime))
                {
                    return Convert.ToDateTime(_queuedToWHTime);
                }
                return null;
            }
        }
}

和一个表(MyTable):

CREATE TABLE webnews_in
(
Id                INT NOT NULL auto_increment,
QueuedToWHTime    VARCHAR (50) NULL
...
PRIMARY KEY (Id)
);

当我试图像这样查询:

var searchRslt=(from m in queryableNews
    orderby m.QueuedToWHTime_DateTime descending
    select m).ToList();

我得到了NotSupportedException …

如何实现在子类中const field哪些必须覆盖,我正在使用.net 4, C#

因为我有许多类all have a const field(具有不同的值)称为'pName'.

所以我想使用接口或抽象类或somthing作为父级并强制这些类覆盖它.

这是CONST领域

我看到一些代码如下,但我没有看到任何删除声明,是否有任何内存泄漏问题？

struct RStatus
{
    int fid;
    int status;
};

void Foo()
{
    vector<RStatus*> rsVec;

    RStatus* rs = null;
    rs = new RStatus(); // memory allocated here!
    rs->fid = 0
    rs->status = 0;
    rsVec.push_back(rs);

}

有一些这样的数据:

name                            number

12_PAGE19901_CHN.DISPLAY_NT     n.115
12_PAGE19901_CHN.DISPLAY_NT     n.114
KAITEST123.DISPLAY_NT           n.110
KAITEST123.DISPLAY_NT           n.109
KAITEST123.DISPLAY_NT           n.108
KAITEST123.DISPLAY_NT           n.107
KAITEST33333.DISPLAY_NT         n.105

我想要检索一些这样的数据:

 name                            number

12_PAGE19901_CHN.DISPLAY_NT     n.115
KAITEST123.DISPLAY_NT           n.110
KAITEST33333.DISPLAY_NT         n.105

我需要first每个特定名称的数字值,这可能吗？

public ActionResult GetFile(string dateStr, string serverName, string foodName)
{
        using (var memoStream = new MemoryStream(1024 * 5))
        {
            using (StreamWriter writer = new StreamWriter(memoStream))
            {
                var dataFilter = new CapacityDataFilter(dateStr, serverName, feedName);
                dataFilter.FilterDataByServerAndFeed();
                writer.WriteLine("Feed, StreamMin, TotalMsgNumber, TotalMsgSize, PeakRateMsgNumber, PeakRateMsgSize");

                foreach (var element in dataFilter.DataInTheDay)
                {
                    writer.WriteLine(string.Format("{0},{1},{2},{3},{4},{5}",
                            element.Feed, element.StreamMin,
                            element.TotalMsgNumber, element.TotalMsgSize,
                            element.PeakRateMsgNumber, element.PeakRateMsgSize));
                }


                return File(memoStream, "text/csv", fileName);
            }
        }
}

Exception Details: System.ObjectDisposedException: Cannot access a closed Stream.

这个动作不起作用,如何进行下载动作？

我正在使用Memcached-for-Windows,请参阅:

http://blog.elijaa.org/index.php?post/2010/08/25/Memcached-1.4.5-for-Windows&similar

我试过用:

sc create "memcached" binPath="C:/memcached/mem
cached.exe" start=auto

但我无法创建Windows服务,也没有警告或错误,只是:

Creates a service entry in the registry and Service Database.
SYNTAX:
sc create [service name] [binPath= ] <option1> <option2>...
CREATE OPTIONS:
NOTE: The option name includes the equal sign.
type= <own|share|interact|kernel|filesys|rec>
   (default = own)
 start= <boot|system|auto|demand|disabled>
   (default = demand)
 error= <normal|severe|critical|ignore>
       (default = normal)
 binPath= <BinaryPathName>
 group= <LoadOrderGroup>
 tag= <yes|no>
 depend= <Dependencies(separated by / (forward slash))>
 obj= <AccountName|ObjectName>
       (default = LocalSystem)
 DisplayName= <display name>
 password= <password>

我正在使用mysql 5.5,这是一个带有literal列表的左连接查询 :

select tbl1.*, details.* 
from ('a', 'b', 'c'... 300+ elements) as 'tbl1' 
left join details
on 
details.id=tbl1.id

但它不起作用!

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''a','b')' at line 1

如何把它list作为一个表？

我正在使用asp.net mvc,但无法访问我的页面,得到404错误.

页面的网址:

本地主机:2334/RAWDATA/EiphoneNews

查看文件的位置:

根目录/查看/ RAWDATA/TNews/Index.cshtml

我的路线:

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(

评论中的空格使网站崩溃

<!--<s:form name="exportNews"id="exportNewsForm" theme="simple"  namespace="/"  action="exportNews" onsubmit="return validate(this);"  method="post"> 
        <s:submit value="Export"  />
         </s:form> --> 

崩溃我的网站的代码是评论.在我在id = ...之前添加一个空格之后,修复了这个bug.

谁能告诉我原因？
