要求不同人员进入查询界面后,只能查询包括自己权限以下的所有人员的销售信息 --看看BOM给一个例子--生成测试数据 create table BOM(ID INT,PID INT,MSG VARCHAR(1000)) insert into BOM select 1,0,NULL insert into BOM select 2,1,NULL insert into BOM select 3,1,NULL insert into BOM select 4,2,NULL insert into BOM select 5,3,NULL insert into BOM select 6,5,NULL insert into BOM select 7,6,NULL go--创建用户定义函数用于取每个父节点下子节点的采购配置信息 create function f_getChild(@ID VARCHAR(10)) returns @t table(ID VARCHAR(10),PID VARCHAR(10),Level INT) as begin declare @i int set @i = 1 insert into @t select ID,PID,@i from BOM where PID = @ID
while @@rowcount<>0 begin set @i = @i + 1
insert into @t select a.ID,a.PID,@i from BOM a,@t b where a.PID=b.ID and b.Level = @i-1 end return end go--执行查询 select ID from dbo.f_getChild(3) go--输出结果 /* ID ---- 5 6 7 */--删除测试数据 drop function f_getChild drop table BOM
不需要建立
我自己建了一个人员管理归属表:
UserId FatherId(上级管理人员ID) 只要在职务表里面增加一个fatherId就可以了
create table BOM(ID INT,PID INT,MSG VARCHAR(1000))
insert into BOM select 1,0,NULL
insert into BOM select 2,1,NULL
insert into BOM select 3,1,NULL
insert into BOM select 4,2,NULL
insert into BOM select 5,3,NULL
insert into BOM select 6,5,NULL
insert into BOM select 7,6,NULL
go--创建用户定义函数用于取每个父节点下子节点的采购配置信息
create function f_getChild(@ID VARCHAR(10))
returns @t table(ID VARCHAR(10),PID VARCHAR(10),Level INT)
as
begin
declare @i int
set @i = 1
insert into @t select ID,PID,@i from BOM where PID = @ID
while @@rowcount<>0
begin
set @i = @i + 1
insert into @t
select
a.ID,a.PID,@i
from
BOM a,@t b
where
a.PID=b.ID and b.Level = @i-1
end
return
end
go--执行查询
select ID from dbo.f_getChild(3)
go--输出结果
/*
ID
----
5
6
7
*/--删除测试数据
drop function f_getChild
drop table BOM
