Cara memilih tanggal setiap Senin dan setiap tanggal Jumat dalam setahun

Anda dapat menggunakan tabel yang sesuai dengan angka, seperti tabel master..spt_values ​​sebagai dasar untuk pembuatan rentang:

;WITH dates AS (
    SELECT DATEADD(DAY,number,CAST('2014-01-01' AS DATE)) d
    FROM master..spt_values WHERE TYPE = 'p'
    AND number < 366
    )

SELECT 
    Week = DATEPART(WEEK, d), 
    DayOfWeek = DATENAME(dw, d), 
    Date = d
FROM dates
WHERE DATENAME(dw, d) IN ('Monday', 'Friday')
-- or use datepart instead as datename might be specific to language
-- WHERE DATEPART(dw, d) IN (2,6)

Contoh keluaran:

Week        DayOfWeek                      Date
