帮个忙呗。实在不会了
表1 d_ry
gh char 工号 主键
sjldgh char 上级领导工号
name varchar(10)
表2 d_ywy
ywdh char(10)业务单号 主键
ywje decimal(9,2) 业务金额
gh char 工号
其中业务员是树状分布,即通过表1知道其上级人员的工号这样串起来
想求任意给定的工号人号,及其所有下属的业务单号,业务金额的明细
下属是指其下级或下级的下级这样的,直到叶

create table #temp

insert into #temp
select gh from d_ry where sjldgh = @sjldgh
while exists (select gh from d_ry x
