sql server - sql query to get content older than 3 weeks -

-

My content table appears (contentID, title, created). I need to get all the content that was created more than 3 hours ago.

The SQL Server database has been created, datetime type.

How about: 

  Content ID, select the title , Where the built-in material was made & lt; DATEADD (week, -3, getdate ());

This takes the question closer to 21 days is fine, clearly it means, but I think it is good to use the terminology used in the question. For example ... For some time ago I was asked to survey average in 1, 50 visitors to one site I described it as ratio of 0.02, and the client was not happy I told the customer that they were the same But I have learned my lesson, and now if I change the way I have been described, I am sure that I comment on that effect, and preferably not to change it in the first place. Wants place If the customer wants 3 weeks, then do it as 3 weeks, not 21 days.

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument.

Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket.

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
