MySQL递归查询当前节点及子节点

 

1.表结构

 

MySQL递归查询当前节点及子节点_MySQL

 

2.查询语句

 

create procedure Pro_GetUnderOrg(in idd varchar(36))begindeclare 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()>0do     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
