MySQL 递归查询 当前节点及子节点

1.表结构

　　

2.查询语句

  
    

   
     create
   
      
   
     procedure
   
      Pro_GetUnderOrg(
   
     in
   
      idd 
   
     varchar
   
     (
   
     36
   
     ))

   
     begin
   
     

   
     declare
   
      lev 
   
     int
   
     ;

   
     set
   
      lev
   
     =
   
     1
   
     ;

   
     drop
   
      
   
     table
   
      
   
     if
   
      
   
     exists
   
      tmp1;
 
   
     CREATE
   
      
   
     TABLE
   
      tmp1(ID 
   
     VARCHAR
   
     (
   
     36
   
     ),OrgName 
   
     varchar
   
     (
   
     50
   
     ),ParentID 
   
     varchar
   
     (
   
     36
   
     ) ,levv 
   
     INT
   
     );
 
   
     INSERT
   
      tmp1 
   
     SELECT
   
      ID,OrgName,ParentID,
   
     1
   
      
   
     FROM
   
      `organization` 
   
     WHERE
   
      ParentID
   
     =
   
     idd;

   
     while
   
      row_count()
   
     >
   
     0
   
     
do
 
   
     set
   
      lev
   
     =
   
     lev
   
     +
   
     1
   
     ;
 
   
     INSERT
   
      tmp1 
   
     SELECT
   
      t.ID,t.`OrgName`,t.`ParentID`,lev 
   
     from
   
      organization t 
   
     join
   
      tmp1 a 
   
     on
   
      t.ParentId
   
     =
   
     a.ID 
   
     AND
   
      levv
   
     =
   
     lev
   
     -
   
     1
   
     ;

   
     end
   
      
   
     while
   
      ;
 
   
     INSERT
   
      tmp1 
   
     SELECT
   
      ID,OrgName,ParentID,
   
     0
   
      
   
     FROM
   
      `organization` 
   
     WHERE
   
      ID
   
     =
   
     idd;
 
   
     SELECT
   
      
   
     *
   
      
   
     FROM
   
      tmp1;

   
     end
   
     ;
  
    

3,调用

  
    

   
     call Pro_GetUnderOrg(
   
     '
   
     9B2AE044-3B51-47FA-A24C-8326BA7B9FD3
   
     '
   
     );
  
    

4,注意： 这种表设计以后一定要加个 路径字段 以后就不用这么费事了，直接 like 查询了
