Question

我的任务是延长两个日期之间的持续时间。我在Excel中执行平均值等，所以我只提取开始和结束日期。由于我们有一个数据源没有添加结束日期，因此我将拉出最旧的行（有多个交易），其中status =＆＃39;已关闭＆＃39;。唯一的问题是，其中一些日期实际上是在报告日期之前。因此，添加了一些逻辑以使用会计期间，如果结束或“关闭”状态将设置为关闭。日期大于报告的日期。如果状态仍设置为“打开”，则此日期也会使用今天的日期作为结束日期。我的问题是会计日期是本月的第一天。我需要做的是更改列＆＃39; end_date＆＃39;的会计日期。到该月的最后一天，或该月的第28天。我搜索了如何做到这一点并找到了一些帮助，但我无法弄清楚如何在这些其他规定发挥作用时得到我需要的东西。任何帮助，将不胜感激。

摘要：我需要在＆＃39; end_date＆＃39;中添加27天的日期。如果他们使用会计日期而不是今天的日期（这些仅适用于来自＆x; xls＆＃39;数据源的记录。

Answer 1

DATEADD()功能可用于在日期之间添加或减去一个时间单位。

SELECT DATEADD(unit of time, number to add, base date)
SELECT DATEADD(day,29,GETDATE())

如果日期符合条件，请在某个日期添加一定天数
