当日期不在table1中时，SQL查询In/Out考勤与空行

Posted 2023-04-12

【中文标题】当日期不在table1中时，SQL查询In/Out考勤与空行

【英文标题】：SQL Query for In/Out time attendance with null row when date not in table1

【发布时间】：2018-05-19 18:33:03

【问题描述】：

我有一个包含以下示例输出的两个表。 tb1 及时，tb2 超时

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实现以下结果：

如果表 2 中的 OINDX 而不是表 1 或表 1 中的 IINDX 而不是表 2 并且如果日期不在两个日期之间的日期中，则我需要获取 null 行，日期仅像这张照片一样

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 datw 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

  where d not in (select [date] from TIMEIN union select [date] from TIMEOUT )  
  and d between CAST(N'2018-02-07' AS Date) and CAST(N'2018-03-01' AS Date)
