sql server - sql select 3 columns and dedupe on two columns -

March 15, 2010

I have a job setup that currently does not have a unique index that selects records from a table I it can only be solved by adding an index on the table and a variety of columns, but for testing purposes in this case, I have to delete the index and then select one which will also remove duplicates based on two columns:

  SELECT DISTINCT [author], [pubDate], [dateadded] FROM [feeds] [Dbo]. [Social Post] Where Cast (False (dateadded as float) datetime) & gt; DATEADD (DAY, DATEDIFF (DAY, 0, GETDATE () - 2), 0) and CAST AS Dettaim (Flo (CAST (on a basket float))) & lt; To DATEADD (DAY, DATEDIFF (DAY, 0, GETDATE ()), 0)    selects all records from the first day and I lose the record by author and pubdate This post can be selected or done before, but it is to find out that it can be done within a selection.   
 
  You can use  GROUP BY  and an  author You can use any of the functions on the  dated  column to get the message, pubadet  results.

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is
not "text/event-stream" -



    When I try to hook my controller to EventSource, it keeps saying:    EventSource Response contains a MIME type ("text / html") that is not "text / event-stream" canceling connection.    I have created the following class to help in handling a handle and preparing the reaction. In this class I believe that I set the  text / event-stream  according to the response.    public class ServerSentEventResult: ActionResult {public representative string GetContent (); Public GetContent Content {get; Set; } Public int version {get; Set; } Public Override Zero ExecuteResult (Controller Context Reference) {if (context == null) {New argument NullException ("Reference"); } If (this.
