Question

我需要编写一个SP来查找经理X下的完整团队。从某种意义上说，我想在管理员X下找到所有直接和间接的报告。我正在使用SQL Server 2005.

Employee表结构是：

EmployeeNumber  FirstName  LastName  ManagerEmployeeNumber

例如，如果SP的输入为Employee Number = 10211，则输出应如下所示：

EmployeeNumber  FirstName  LastName  ManagerEmployeeNumber
13903           Anil       S         10211
1260            David      D         13903
8079            Donald     K         1260

我已经编写了所需的东西，以便在以下函数中找到经理X下的完整团队：

ALTER FUNCTION [dbo].[FullTeamUnderManager1](@ManagerId int)  
RETURNS   
@EmployeeList TABLE   
( 
 EmployeeName Varchar(200) 
)  
AS  
BEGIN  

 With hierarchy(EmployeeName, Employee_Id, SupEmp_Id, Depth) as  
 (  
  Select (first_name + ', ' + last_name) EmployeeName, employee_number, employee_number as supemp_id, 0 as depth  
     From dbo.employee  
     Where employee_number = @ManagerId  
  union all   
  Select (child.first_name + ', ' + child.last_name), child.employee_number, child.manager_employee_number, parent.depth + 1   
  From dbo.employee As child  
  Inner Join hierarchy As parent  
      On child.manager_employee_number = parent.Employee_Id  
     Where child.employee_number != parent.Employee_Id  

 )  
 insert into @EmployeeList(EmployeeName)  
  select EmployeeName from hierarchy where depth > 0  
  order by EmployeeName
 RETURN   
END

我需要将它与下面的SP结合起来。输出应该是单个列“EmployeeName”

ALTER PROCEDURE [dbo].[spGetCorpDirDistributionTableUsers]            
@activeOnly bit = 1,            
@employeesOnly bit = 1,            
@isAllowedNonEmployees bit = 0,      
@isAllowedNonEmployeesInOrgChart bit = 0, 
@login_employee_number INT = NULL,      
@IsGetLocations bit = 0,
@Location_IDLIST VARCHAR(MAX) = NULL,
@IsGetDepartments bit = 0,
@Department_IDLIST VARCHAR(MAX) = NULL,
@IsGetDirectReports bit = 0,
@IsGetDirectReportsManagers bit = 0,
@IsGetAllManagers bit=0,
@manager_employee_number INT

   AS    
   DECLARE @employeeTypeId int       

   SET @employeeTypeId = 1           
   SET @isAllowedNonEmployees = ISNULL(@isAllowedNonEmployees, 0) 
   SET @isAllowedNonEmployeesInOrgChart  = ISNULL(@isAllowedNonEmployeesInOrgChart, 0)               
   SET @IsGetDirectReports = ISNULL(@IsGetDirectReports, 0) 
   SET @IsGetDirectReportsManagers  = ISNULL(@IsGetDirectReportsManagers, 0)

   SELECT         
    (e1.first_name + ', ' + e1.last_name) EmployeeName,
   FROM EMPLOYEE e1           
   LEFT OUTER JOIN EMPLOYEE e2 on e1.manager_employee_number = e2.employee_number             
   INNER JOIN LOCATION loc ON e1.location_id = loc.location_id   
   INNER JOIN DEPARTMENT dep ON e1.department_id = dep.department_id                  
   LEFT OUTER JOIN EMPLOYEE_TYPE emptype ON e1.employee_type_id = emptype.employee_type_id            
   WHERE          
     e1.visible = 1 and             
     (@activeOnly = 0 OR @activeOnly IS NULL OR e1.active_flag = 1) and            
     (@isAllowedNonEmployees = 1 or e1.employee_type_id = @employeeTypeId) and             
     (@employeesOnly = 0 or e1.employee_type_id = @employeeTypeId) and  



  --Location
  (@IsGetLocations=0 OR
  (COALESCE(@Location_IDLIST,'%') = '%' OR e1.location_id IN (SELECT Segment FROM dbo.fn_GetParsedValues(@Location_IDLIST,',')))) and

  --Department
  (@IsGetDepartments=0 OR
  (COALESCE(@Department_IDLIST,'%') = '%' OR e1.Department_ID IN (SELECT Segment FROM dbo.fn_GetParsedValues(@Department_IDLIST,',')))) and      

  --IsGetDirectReports
  (@IsGetDirectReports=0 OR
    ((e1.manager_employee_number = @manager_employee_number and e1.active_flag = 1 and e1.visible = 1)    
      and ((@isAllowedNonEmployees = 1 and  @isAllowedNonEmployeesInOrgChart = 1) or e1.employee_type_id = @employeeTypeId))) and

  --IsGetDirectReportsManagers
  (@IsGetDirectReportsManagers=0 OR
  ((e1.manager_employee_number = @manager_employee_number and e1.active_flag = 1 and e1.visible = 1)    
      and ((@isAllowedNonEmployees = 1 and  @isAllowedNonEmployeesInOrgChart = 1) or e1.employee_type_id = @employeeTypeId)
      and (select count(*) from employee e3 where manager_employee_number = e1.employee_number and active_flag = 1 and ((@isAllowedNonEmployees = 1 and  @isAllowedNonEmployeesInOrgChart = 1) or e3.employee_type_id = @employeeTypeId))>0
    )) and

  --IsGetAllManagers
  (@IsGetAllManagers=0 OR
  ((SELECT count(*) FROM dbo.employee e2 WHERE e2.manager_employee_number = e1.employee_number ) > 0) AND
    @IsGetDirectReports=0 AND @IsGetDirectReportsManagers=0)

order by EmployeeName

任何人请帮忙...提前致谢...

Answer 1

试试这个：

WITH CTE
AS
(
    SELECT 
      EmployeeNumber, FirstNAme, LastName, ManagerEmployeeNumber 
    FROM Emps
    WHERE EmployeeNumber = @EmpNumberToFind
    UNION ALL
    SELECT t.*
    FROM CTE c
    INNER JOIN Emps t ON c.EmployeeNumber = t.ManagerEmployeeNumber
) 
SELECT * 
FROM CTE;

SQL Fiddle Demo

例如，对于EmployeeNumber = 13903，这会给你：

| EMPLOYEENUMBER | FIRSTNAME | LASTNAME | MANAGEREMPLOYEENUMBER |
-----------------------------------------------------------------
|          13903 |      Anil |        S |                 10211 |
|           1260 |     David |        D |                 13903 |
|           8079 |    Donald |        K |                  1260 |
