怎么获取递归树的所有叶子节点sql
展开全部
用标准sql的with实现递归查询（sql2005以上肯定支持，sql2000不清楚是否支持）：
with subqry(id,name,pid) as (
select id,name,pid from test1 where id = 5
union all
select test1.id,test1.name,test1.pid from test1,subqry
where test1.pid = subqry.id
)
select * from subqry;
with subqry(id,name,pid) as (
select id,name,pid from test1 where id = 5
union all
select test1.id,test1.name,test1.pid from test1,subqry
where test1.pid = subqry.id
)
select * from subqry;
