dayofweek

问题 I need some help as I am stuck. This is using SQL and Coldfusion. Basically I have a table which list a completion of certain tickets along with what date they were marked complete. This table has district and area for example, which is used in the GROUP BY. So I want to count every ticket that was done on every week of the year, the user selects for example running the report. I will list a little of the SQL I have at the moment. SELECT SUM(CASE WHEN DATEPART(ww, completionDate) = 1 THEN 1

问题 I tried writing the code for finding the day of the week for a given date using Zeller's Congruence but I'm not getting the correct output. What's wrong with my code? #include <stdio.h> #include <math.h> int main() { int h,q,m,k,j,day,month,year; printf("Enter the date (dd/mm/yyyy)\n"); scanf("%i/%i/%i",&day,&month,&year); if(month == 1) { month = 13; year--; } if (month == 2) { month = 14; year--; } q = day; m = month; k = year % 100; j = year / 100; h = q + floor(13/5*(m+1)) + k + floor(k/4

问题 I have a date string in (yyyy-mm-dd) format, how can I get the weekday name from it? Example: For the string "2013-07-31", the output would be "Wednesday" For today's date using new Date() , the output would be based on the current day of week 回答1: Use this function, comes with date string validation: If you include this function somewhere in your project, // Accepts a Date object or date string that is recognized by the Date.parse() method function getDayOfWeek(date) { var dayOfWeek = new

问题 I'm working on an assignment, and my goal is to create a class that prints the day of the week given a date. When prompted for input, if the user enters nothing, the program is stopped. Otherwise, if the user enters a date, the program provides the day of the week and then continues to re-prompt the user. The date the user inputs will be in the format of m d y, or for example, 1 10 2017 for January 10th, 2017. What I have so far does everything I need, except it uses the current day, month,

问题 I stored into my database as integer day values. From a string array I was getting the day as string. public static string[] _dayofweek = new string[] {"SUNDAY","MONDAY","TUESDAY","WEDNESDAY","THURSDAY","FRIDAY","SATURDAY"}; However, now I want to get the name of day relatively to cultureinfo not only as fixed in english. Is it possible to get the names of week from this stored day number ? 回答1: The easiest way is to use ToString("dddd") on a DateTime . I would pick an arbitrary Sunday and

问题 I am using the recent java.time package and in particular the day of week getter of LocalDate. I get a nice DayOfWeek enum when calling LocalDate.getDayOfWeek() . However, my code should be compatible with some older part of the application that uses the integer value of a Calendar weekday, i.e. obtained from the code Calendar.get(DAY_OF_WEEK) . Obviously, in the DayOfWeek enum, SUNDAY value is 7, and in Calendar DAY_OF_WEEK field, SUNDAY value is 1. So, what choices do I have to convert one
