how to simplify this statement? php mysql -

-

I need to retrieve many selections from the mysql table, I need to make the statement easier

This is my statement 

  $ starard = dateelect $ enddate = dateelect select SELECT count (different (customer)) my_table as a customer where 'date_field' between '$ startdate' and ' Enddate 'SELECT count (different (customer)) as computer 1 my_table where computer = 1 and date_field between' $ startdate 'and select' $ enddate 'count (different (customer)) as computeris2 where my_table compute I have around 10 fields, each with 4 or 5 values ​​(option) in each field (such as a computer), between 'r = 2' and 'date_field' between '$ startdate' and '$ enddate'   
 Want to count specific customers and all between 2 dates  
 The other problem is that this date is the timestamp of mysql, it does not return true and does not exclude today's record, unless it does not select the date of tomorrow, it works , I think that this is a one-time issue, how can I make it? Can I fix the problem of time from time to time with the date of calculation?   
 
 You  date / time problem For the rest, you can use conditional aggregation to do everything in a query:  
  Selection number as customer (different (customer)), count (different cases When computer = 1 subscriber ends) as computer 1, counting (different position when computer = 2 then customer end) my_table as computer 2 where '$ startdate' and '$ enddate' between date (date_field);   
 This value stores values ​​as separate columns instead of separate rows.

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
