Answer 1

我想你的意思是：

SELECT '(Current Week)'
UNION SELECT Convert(varchar, DateAdd(dd, -7, GetDate()), 101)
UNION SELECT Convert(varchar, DateAdd(dd, -14, GetDate()), 101)
UNION SELECT Convert(varchar, DateAdd(dd, -21, GetDate()), 101)
UNION SELECT Convert(varchar, DateAdd(dd, -28, GetDate()), 101)
UNION SELECT Convert(varchar, DateAdd(dd, -35, GetDate()), 101)
UNION SELECT Convert(varchar, DateAdd(dd, -42, GetDate()), 101)
order by 1
