Mysql 2 Tables join Limit Result return from both Table -

September 15, 2012

I am trying this requirement for a few hours, but I do not know that I'm not getting the desired result .

I have two tables.

  ** Main comment table ----------------------------- ------ ----------------------------------------- ID | Comments | Date_commented | On comment_ | Comment 1 by 1 hello world ********* 321 123 hair comment table ----------------------------- - --------------------------------------------- ID | MainpostID | Child_comment_data | Comment | Hetto World's 1st Child's Comment # 456 ********************************************************************* My requirement: 
 I want to retrieve the first 10 main comments with each other for chillmement. Main Comment I would like to limit the number of child annotations for each main comment.   What I tried:  
  SELECT maincomment.comments, maincomment from childcomment.child_comment_data maincomment LEFT JOIN.ID = Basic comment. MySpotid and Main Comet Dot Commendants = Child Comment Dotmed by WHERE maincomment.id = childcomment.mainpostID Date Posted DESC LIMIT 10    Result: I'm receiving just 10 key notifications each The main number of children for the main comment is just 1. I have to return 5 children's work to everyone's needs.  
 Anyone will help with some tips / questions.  
 Thank you very much.   
 
  You can use this solution:  
  SELECT a . *, B * FROM (SELECT * 10 from the DESC limit posted on the date of the main order) Include a bottom (Select one. *) Join one of the children's education on B. B. Maiposted and B.Mimopostid AID and LT; = AID Hewing COUNT (1)    This latest 5 comments of the latest child gets up to 10 latest keynotes, if any special comment If there is no child comment, child-comment data will include the  NULL  value.

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,
