Question

我有一个带有以下示例输出的两个表。 tb1是及时的，tb2是时间

如果tb2中的行不在tb2中或tb1中的行不在tb1中，我想构建一个查询以使用空值来实现以下结果：

如果表2中的OINDX而不是table1中的OINDX而不是table2中的IINDX而不是table2中的日期，并且如果日期不是两个日期之间的日期，那么我需要获取null只有像这张照片的日期获取空行

此代码创建两个表来尝试代码并帮助我

我使用此代码获取两个数据之间的列表日期

DECLARE @Date1 DATE = '2018-02-07'; DECLARE @Date2 DATE = '2018-02-28';
SELECT DATEADD(DAY,number,@Date1) [Date] FROM master..spt_values
WHERE type = 'P' AND DATEADD(DAY,number,@Date1) <= @Date2
