Question

我需要创建一个选择查询，查看员工列表并确定他们是否进入。该表将包含以下数据：

雇员，日期/时间

我需要找到任何拥有超过1条记录的员工，然后切换新列以确定员工是否根据日期/时间签入或签出。

实施例

999, 2016-01-01: 9:00     -- This would have a column with 1 added
999, 2016-01-01: 15:00    -- This would have a column with 2 added
999, 2016-01-01: 18:00    -- This would go back to 1

我需要这个来查看表格中的所有行。这可能吗。我无权对原始表进行任何更改。

Answer 1

也许查看奇数或偶数？

SELECT
 Employee_id,
 Date,
 IF(COUNT(*) % 2 = 0, 1, 2) AS 'Lastvisit'
FROM 
 table

Answer 2

我希望它能够发挥作用

    SELECT employeeid,Cast (date/time as date),
   (RANK() OVER   
   (PARTITION BY employeeid ORDER BY date/time)) as 'in/out'
    FROM table 
    GROUP BY employeeid,Cast (date/time as date)

在sql select语句中添加一个Check-Out指示符
