sql - SQLPlus How to print the MAX of COUNT(*)? -

-

I need help printing the highest number of employees, because Max (COUNT (*)) is actually Does not work, can anyone help me in this?

Say that I have two table names which are department and ampe, each of which is deptno and empdeptno respectively. I need to calculate each department in each employee: 

  SELECT dept.dptname "Department", (SELECT COUNT (*) emp WHERE emp.empdeptno = dept.deptno) "employees Number "from DEP order to COUNT (*) DESC;   
 How do you print the department with the highest employee number without using LIMIT with ORDER BY?  
 
  SELECT dept.dptname "Department", as COUNT (emp.empdeptno) " Number of Employees "from DEPT DEPTNO = emp.empdeptNO GROUP BY DEPT.Deptname ORDER BY COUNT (emp.empdeptno) DESC   
 You can write by  Group by DEPTUniqueDepartmentKey, dept.dptname  If the dept.dptname key is unlikely   
 you mention the alias by the name of your SQL taste:  Group "Department"  May be needed.

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...
