静态会计年度的自定义周

Question

I'm trying to create logic for custom weeks in a fiscal year that always starts on Jan 1st, and ends on Dec 31st. I was able to get the correct week numbers for each month, but can't customize the weeks correctly for the year. For instance, the data still shows week 53 for the first two days of January 2016. In short, Week 1 should start on 1/1/yyyy and week 52 or 53 (in some cases) end on 12/31/yyyy.

Any suggestions will be greatly appreciated. Thank you.

Answer 1

MYSQL

SELECT CEILING(DAYOFYEAR('your date') / 7)

POSTGRES

SELECT CEILING(EXTRACT('DOY' FROM DATE 'your date') / 7)

ORACLE

SELECT CEIL(TO_CHAR(SYSDATE, 'DDD') / 7)

Answer 2

试试这个你可以将@YourDate替换为你想要检查的日期

SELECT DATEPART( wk, @YourDate)
