我想將日期編號轉換為日期名稱

Question

我想在一列中獲取日期和日期名稱，我為其創建了動態日期，但我無法從日期編號創建日期名稱並將日期和日期名稱混合在一列中。 請幫忙。

T 
| where name has "Samplelog"
| extend Eventdate = strcat(datetime_part("day",timestamp))
| extend day_strg = tostring(Eventdate)
| extend day_Alp = dynamic({"0":"Sun", "1":"Mon", "2":"Tue", "3": "Wed", "4": "Thu", "5":"Fri", "6": "Sat"})
| extend day_num = dayofweek(timestamp) / 1d
| extend months = dynamic({"1":"Jan", "2":"Feb", "3":"Mar", "4":"Apr","5":"May","6":"Jun","7":"Jul","8":"Aug","9":"Sep","10":"Oct","11":"Nov","12":"Dec"})
| extend Eventdate = strcat(datetime_part("day",timestamp),"-",months[tostring(getmonth(timestamp))], "-", getyear(timestamp))
| extend Week_Num = case(day_strg in (range(1, 7, 1)), "1", day_strg in (range(8, 14, 1)), "2",day_strg in (range(15, 21, 1)), "3",day_strg in (range(22, 31, 1)), "4", "0")
| extend weekend = iff(Week_Num in (2,4) and day_num == 6 or day_num == 0, "weekend", "working day")
//| summarize Count=count() by bin(timestamp,1d)

Answer 1

let prm_day_of_week = dynamic(["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]);
let prm_month = dynamic(["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]);
let mydata = materialize (range i from 1 to 10 step 1 | extend dttm = ago(rand()*1d*365));
mydata
| extend dayofweek = dayofweek(dttm), monthofyear = monthofyear(dttm)
| extend dayofweek_name = prm_day_of_week[toint(dayofweek/1d)], monthofyear_name = prm_month[monthofyear-1]
