ORA-01436错误,即“connect by loop in user data”,是Oracle数据库中在使用CONNECT BY子句进行层次查询时遇到的一个错误。这个错误表明在层次查询的递归过程中,用户数据(即START WITH和CONNECT BY子句中引用的列)形成了一个循环,导致查询无法正确终止。 2. 导致ORA-01436错误的常见原因 递归关系定义错误:在CONNECT...
CONNECT BY PRIOR jt.terr_id = jt.parent_territory_id ; Its been observed that query throw error at 2501 row. I have tried to find out the cyclic loop records by using the following query: SELECT sys_connect_by_path(jt.terr_id,'/')...
start with part_id=1 connect by prior part_id=parent_id order by level; 上面两个sql执行的时候都会报ORA-01436: CONNECT BY loop in user data 解决方案入下: 方案1:在connect by 后面加上nocycle ,不循环。得到的结果可能就不是你想要的了。 方案2:把第一条记录的parent_id 置为null ,这样做就不...
01436. 00000 - "CONNECT BY loop in user data" *Cause: *Action: 原因: 分层查询中存在上下层互为父子节点 处理方法: 在connect by后面加上NOCYCLE关键字,用connect_by_iscycle伪列定位出存在互为父子循环的具体节点,修改出错的数据。 connect_by_iscycle必须要跟关键字NOCYCLE结合起来使用 Oracle “CONNECT BY...
