--树形sql查询
WITH TREE AS( --创建一个虚拟表
SELECT * FROM sys_organiz --指定需要查询的表
WHERE organize_code = '100000' -- 指定父节点条件
UNION ALL --联合查询
SELECT sys_organiz.* FROM sys_organiz,TREE
WHERE TREE.organize_code = sys_organiz.organize_parent_code
)
SELECT * F
很多人可能想要查询整个树形表关联的内容都会通过循环递归来查…事实上在微软在SQL2005或以上版本就能用别的语法进行查询，下面是示例。
--通过子节点查询父节点
WITH
TREE AS(
SELECT * FROM Areas
WHERE id = 6 -- 要查询的子 id
UNION ALL
SELECT Areas.* FROM Areas, TREE
WHERE TREE.PId = Areas.Id
)
SELECT Area FROM TREE
--通过父节点查询子节点
