步步为营-82-获取当前部门的所有上级节点-存储过程实现

Posted 2020-09-26 逍遥小天狼

说明:需求部门表自身关联 表字段OrgUnitGUID(主键) OrgUnitName(名称) UpperOrgUnitGUID(自身关联)

通过存储过程实现.参考博客http://blog.csdn.net/apollokk/article/details/8330299

现将内容简画

1 演练

CREATE TABLE [dbo].[department](  
 [ID] [decimal](18, 0) IDENTITY(1,1) NOT NULL,  
 [department] [nvarchar](20) NULL,  
 [pid] [decimal](18, 0) NULL   
)  

创建表

CREATE PROCEDURE [dbo].[getChildDeptById]   
 @id INT  
AS  
BEGIN  
 -- SET NOCOUNT ON added to prevent extra result sets from  
 -- interfering with SELECT statements.  
 -- SET NOCOUNT ON;  
  
 WITH   dept  
          AS ( SELECT   *  
               FROM     dbo.department  
               WHERE    pid = @id  
               UNION ALL  
               SELECT   d.*  
               FROM     dbo.department d  
                        INNER JOIN dept ON d.pid = dept.id  
             )  
    SELECT  *  
    FROM    dept  
END  

根据指定部门的Id获取所有下级部门

CREATE PROCEDURE [dbo].[getParentDeptById]   
 @id INT  
AS  
BEGIN  
 -- SET NOCOUNT ON added to prevent extra result sets from  
 -- interfering with SELECT statements.  
 -- SET NOCOUNT ON;   
 WITH   dept  
          AS ( SELECT   dp.*  
               FROM     dbo.department d INNER JOIN dbo.department dp ON d.pid=dp.ID  
               WHERE    d.id = @id  
               UNION ALL  
               SELECT   d.*  
               FROM     dbo.department d  
                        INNER JOIN dept ON d.id = dept.pid  
             )  
    SELECT  *  
    FROM    dept   
END

根据指定部门的ID创建所有上级部门

 -- SET NOCOUNT ON;   
 WITH   dept  
          AS (   
              SELECT   dp.OrgUnitName ,d.OrgUnitGUID,d.UpperOrgUnitGUID
               FROM     dbo.TB_OrganizationUnit d INNER JOIN dbo.TB_OrganizationUnit dp ON d.UpperOrgUnitGUID=dp.OrgUnitGUID  
               WHERE    d.OrgUnitGUID =@OrgUnitGUID   
               UNION ALL  
               SELECT   d.OrgUnitName ,d.OrgUnitGUID,d.UpperOrgUnitGUID
               FROM     dbo.TB_OrganizationUnit d  
                        INNER JOIN dept ON d.OrgUnitGUID = dept.UpperOrgUnitGUID 
             )  
    SELECT  *  
    FROM    dept   
END 

存储过程

 //经办人部门的设置
            //获取所有上级部门 通过存储过程
            DataSet deptmentDS = TBContractSearch.GetParentOrganizationUnitByOrgUnitGUID(CurrentUser.OrganizationId);
            if (deptmentDS != null && deptmentDS.Tables[0].Rows.Count>0)
            {
                int count = deptmentDS.Tables[0].Rows.Count;
                StringBuilder deptNameSB = new StringBuilder(); 
                for (int i = count-1; i > 0; i--)
                {
                    deptNameSB.Append(deptmentDS.Tables[0].Rows[i]["OrgUnitName"]);
                    deptNameSB.Append(\'/\');
                }
                string deptName = deptNameSB.ToString().TrimEnd(\'/\');
                this.attnDepart.Text = deptName;

C#中调用

3 运行效果

 

同一个表中有上下级关系,如果关系比较简单,或者获取的层级比较小的话可以通过表的连接实现

     SELECT   d.ObjID1,d.ObjName1 as 项目,d.ObjID2,d.ObjName2 as 区域  ,d2.ObjID2,d2.ObjName2 公司
     FROM     dbo.[MDS_Hr_ObjRelation]  d , dbo.[MDS_Hr_ObjRelation] d2 
     WHERE    d.ObjID1  = \'3C20E046-D79E-447E-98B7-DE6A7472EC88\' 
     and d2.ObjID1=(SELECT  d2.ObjID2  FROM  dbo.[MDS_Hr_ObjRelation]  d2 WHERE    d2.ObjID1  = \'3C20E046-D79E-447E-98B7-DE6A7472EC88\') 
     

低层级获取方法
