sql - is there any `backspace` character in mssql for string? -

-

Below is the query for a string company description by adding name, address 1 and address 2. And here I am using the concatenate APPT SEP ('') for the ISNULL () function if the column is zero. 

  Select name as compdeeatils from Table Companie + ',' + isnull (Address1, '') + ',' + isnull (Address2, ') where id = 4 < / Code>  
 This is the issue of the question, because address 1 or address2 is zero. It will spoil the comma before the empty space which I do not want ..  
 If address 1 and address 2 tap, then result will be  name,  how can I remove it?  Is there any backspace features in mssql ??    
 
 
 I have found the answer to this simple argument .. inside the ISNULL () function  Add Coma. Select   
  name + isnull (',' + 1 address, '') + isnull (',' +2, '') where compounds as compounds ID = 4   
  Note : The name will not give  NULL  in my case. In case the name is also zero, this answer is not applicable.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
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. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
