❶ sql级联查询
select * from #T
❷ SQL 2005中关于两张表级联查询的问题，求高手！！
select b.城市名 起慧胡始兄碧悔城市,c.城市名 终点城市
from road a,city b,city c
where a.startcityId=b.cityId and a.endcityId=c.cityId
其实和普通的羡正关联查询一样
就是路线表里的起始城市和city里的关联一次，终点城市再和city里的关联一次
--补充--
select b.城市名 起始城市,c.城市名 终点城市
from road a
inner join city b
on a.startcityId=b.cityId
inner join city c
on a.endcityId=c.cityId
❸ 问一个关于SQL级联查询的问题
WHERE a.Count != b.Count OR b.Count IS NULL
❹ sql级联查询问题
出来的东颂衡西 不能与你的 虚拟表 关联培首上吗
我用的Sqlserver
虚拟表指野中做的是什么？搞点伪代码
可以先放进临时表里撒
#表名
❺ sql怎么查询级联选项卡
id pid
1 0
2 0
3 1
4 1
5 1
select * from 表 where pid='1';//pid=0为一级瞎悔，亮乎pid=1或2 为二敬神悉级
❻ 俺是Sql业余,请教高手Sql库中两个表级联查询问题 ,急 !!!!
建立如下函数，以解决全拼音的情况，
调用时用Select dbo.f_GetPy(汉字，分隔符)
以下是函数创建方法：
CREATE function f_GetPy(@str varchar(100),@separator varchar(10))
returns varchar(8000)
as
begin
declare @re varchar(8000)
--生成临时表

Create View View_C

❼ SQL级联查询，部门表自连接，需要查出某个部门的上级部门及其上上级部门，上级部门无限个，如何查询
用(select…start with…connect by…prior) 具体给你个参考地址：http://www.cnblogs.com/linjiqin/archive/2013/06/24/3152674.html
❽ SQL级联查询 商品类型级联菜单查询
就是几个表单的联合查询，不难的。所有关联字段link起来就好了。因为你的问题里面就讲到了关联的字段，无法给出具体的sql语句。你可以hi我，告诉你详细的操作
❾ sqlserver2000的级联删除和级联查询
你员工表和关系表重名了，而且数据冗余了，不需要客户编号。
客户表client_Table
客户编号 clientId int 4
客户姓名 clientName nvarchar 20
客户公司 clientCompany nvarchar 50
员工表user_Table
用户编号 userId int 4
用户姓名 userName nvarchar 50
用户密码 userPwd varchar 20
关系表userclient_Table
关系编号 userclientId Int 4
用户编号 userId Int 4
客户编号 clientId Int 4
根据员工查询客户：
select client_Table.clientId ,client_Table.clientName ,client_Table.clientCompany
from client_Table
left join userclient_Table on client_Table.clientId =userclient_Table.clientId
left join user_Table on userclient_Table.userId=user_Table.userId
where user_Table.userId =员工ID
根宴肆据员工删除客户：
根据前面查询出来的客户ID逐条删裂唤除，这个看你是纯SQL操作晌源轿还是在编程工具里操作。
