我创建了Employee,Department和EmpDept Table。
这里的EmpDept表是Junction Table。
EmpDept(Junction Table)
EmpID DeptID
101 502
103 501
102 504
104 502
105 502
106 505
107 507
108 509
在这里," EmpId "引自" 员工"表和" EmpId "是主键," DeptId " 不 是从" 部门"引用的表
Employee
EmpID EmpName
101 Shama
103 Varun
102 Joesph
104 Ram
105 Ravi
106 Deva
107 Mukund
此处 EmpId是主键。
Department
DeptName DeptID
x 501
502
J 503
R 504
A 505
D 506
M 507
z 508
C 509
现在,我必须获得 EmpDept 表中的重复值,并显示具有相同名称的相应 EmpName 。
答案 0 :(得分:0)
declare @DepIDTemp int
set @DepIDTemp=(select EmpDept.DepartmentId
from EmpDept
group by EmpDept.DepartmentId
having count(EmpDept.DepartmentId)>1)
Select DEPARTMENT.DepartmentId, DepartmentName,EMPLOYEE.EmployeeName,EMPLOYEE.EmployeeId from
DEPARTMENT
join EmpDept on EmpDept.DEPARTMENTID=DEPARTMENT.DepartmentId
join EMPLOYEE on EmpDept.EMPLOYEEID=EMPLOYEE.EmployeeId
where DEPARTMENT.DepartmentId=@DepIDTemp;
这是我的解决方案。
