mysql - Select all post and its comments for a specific user -

-

I have a general situation, I want to choose all posts and comments for a specific user. For example: 

  1) Post: 1 (post id), some title, some text 2 (post id), some title, some text comments: 1, 1 (post id), comment comment, comment Text, User ID (1 - 2, 1 (Post ID), CommentTitle, CommentTest, UserID (1 - from second table) 3, 2 (Post ID), CommentTitle, CommentTest, UserID (2 - from second table) 4, 2 ( Post id), comment title, comment text, UserId (2 - from second table)   
 for example , I want to select the first post in a result set and his comments in other results as determined by the User ID. In short, I would like to select all the comments and comments made by the user. Can anyone help me? And I was thinking of making SP as a post ID parameter, but I had problems.   
 
 
 This selects All posts are  Select  Post from where in Post ID (select PostID from comments where URIID = 1);   
 Select all these comments and comments:  
  Postp From SELECT *, comments ASC WHERE C.PostID = P.PostID and C.UserID C. 1 group by COMMENT id;   
 (not tested, but should work)

For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging.
