Sql server 这个查询的输出是什么？

我想你的意思是：

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

没有任何背景，这是意料之中的。你们太快了，无法抓住一个问题并结束它。在你停止工作之前，至少给OP一个机会来澄清他想要达到的目标。也许在船头上开一枪警告？

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
