Question

我正在使用join从所有表中获取所有值，但它显示所有行中的所有匹配列。

我尝试了以下查询：

SELECT  ROW_NUMBER() OVER (ORDER BY A.emp_code) AS SNo, 
cast(datepart(dd,A.att_date) as int) as Attdate
A.att_date,b.emp_code as EmpNo,A.in_time,A.out_time,dbo.late_set.remark
FROM dbo.Daily_attendance_data A 
LEFT OUTER JOIN dbo.employee B  ON (A.emp_id = B.emp_id)
LEFT OUTER JOIN dbo.departments tt ON (B.dept_id = tt.dept_id)
LEFT OUTER JOIN dbo.groups ON (B.group_id=dbo.groups.group_id) 
LEFT OUTER JOIN dbo.late_set ON (B.emp_id=dbo.late_set.emp_id) 
 LEFT OUTER JOIN
                  dbo.companies ON B.company_id= dbo.companies.company_id
                  where att_date between '2019-01-02' 
and '2019-01-05' and( a.emp_id=2 or a.emp_id=46 or a.emp_id=28)

但是我得到如下输出：

1   2019-01-03  1002    NULL    NULL    Due to Bus BreakDown
2   2019-01-02  1002    2019-01-02 07:06:49.000 NULL    Due to Bus BreakDown

我尝试过，但是在所有列中都给出相同的值。

需要所有匹配的值，并且与联接不匹配
