select - Adding Columns in SQL -

-

I have a selected query in this equation

Monitoring Fees "+" CCN Fees "+" WKRPT fees "+" Monarchy fees "+" Client dashboard fees "+" Take control server fees "+" Patch Management Server Fees "+" Remote Batterbair Server Fees "
" Total Capped Server Fees "

I see a problem is that it will only add if there is a value in each column but I want to add it Even if there is no data.

For the remote background server, the fees do not come by September of 2013. So the total closed server charge equation is not adding to the others until everything , It is starting in September 2013 instead of all the years.

some columns You are returning to NULL . For example: 

  ISNULL ("monitoring fee", 0) + ISNULL ("CCN fee", 0) Instead of 0 < For the return of / code> + I ("client dashboard fees", 0) + ISNULL ("Take control server charge", 0) + ISNULL ("Patch Management Server Fees", 0) + ISNULL ( "Remote background server charges", 0) "Total capsed server fees" as   
 I think you are using SQL Server  
 If you If you are using MySQL then the same function is  IFNULL . IFNULL ("CCN Fees", 0) + IFNULL ("WkRpt Fees", 0) + IFNULL ("MonRpt Fees", 0) + IFNULL ("Client Dashboard Fees", 0) + IFNULL ("Take Control Server Fees" "Total Capped Server Fees" as the "Patch Management Server Fee", 0) + IFNULL ("Remote Background Server Fees", 0). >

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

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...
