问题是我需要在两天之内获得week_ids。我需要它的功能
或者你会尽快帮我解决问题
答案 0 :(得分：1)
一个简单的SELECT WHERE BETWEEN应该为你完成这项工作。将两个日期作为参数传递，并
SELECT week_id FROM TBL_S3_FISCALWEEKS_1
WHERE WeekStartDate BETWEEN @DateParam1 AND @DateParam2
即使确切的日期没有出现在WeekStartDate
中，这也会有效答案 1 :(得分：0)
所以你想要一个返回week_id的查询或函数，如果你提供一个日期（即使它是一个介于你的week_startdate和week_enddate之间的日期），对吗？
您可能想尝试以下查询：
SELECT week_id
FROM weeks
WHERE DATEDIFF(dd, week_startdate, input_date) < 7
AND DATEDIFF(dd, week_startdate, input_date) > 0
查看MSDN DATEDIFF参考，了解有关DATEDIFF的更多信息。
