Mysql: Select all data between two dates -

-

I have a mysql table with data connected to the date, each row has data and a date, such as: 

  2009-06-25 75 2009-07-01 100 2009-07-02 120   
 I have a mysql query which can be used for all the data between two dates Selects. The question is:  
  Select data from Tbl Date between date and date 2 Date   
 My problem is that I have a date 1 and date 2 Even if there is no data for the day.  
 So my query remembers those dates which are empty between 2009-06-25 and 2009-07-01.  
 Can I add these dates to data as just 0 in some way?   
 
 
 You can use a concept that is often referred to as the 'calendar table As a 'How to make Calendar tables in MySQL, there is a good guide to this:  
  - Create some basic features Create table entries (INTEGER); INtsER ints value (0), (1), (2), (3), (4), (5), (6), (7), (8), (9); - Works for only 100 days, join more entries and select more cal.date, tbl.data FROM (Select '2009-06-25' + INTERVAL ai * 10 + 2 days as a join date Ints b ORDER BY AI * 10 + 2) Leave Cal and do TLL on Cal Detet = TBL Date, where between '06 -06-2006 'and' 2009-07-01 'CLDAET;   
 You may want to create a table  cal  instead of a subtext.

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...
