哪位大神帮我写条sql啊,急求
表结构是这样的

 id lot_no customer total no
  1 G632#0005 小A 300 T1  
  2 G132#0001 小B 200 T2
  3 G132#0002 小B 500 T2

 
我要查询出来的结果是这样的

lot_no customer total no
 G632 小A 300 T1
 G132 小B 700 T2
请问这条sql改怎么写啊?

select lot_no,customer,sum(total ) ,no from table group by lot_no,no,customer

什么数据库?
for example
SQL code
select distinct substr(lot_no, 1, instr(lot_no, '#')-1) as lot_no,
       customer, total, no
  from table

------解决方案--------------------
8好意思,错了,LZ不是选出不同,而是求和
SQL code
select substr(lot_no, 1, instr(lot_no, '#')-1) as lot_no, 
       customer, sum(total) ,no 
  from table 
  group by lot_no,no,customer

------解决方案--------------------
select substr(lot_no,1,4) as lot_no ,customer ,sum(total) ,no from 表 group by substr(lot_no,1,4),customer ,no
------解决方案--------------------
这是MySQL的
SQL code
 
SELECT MID(lot_no,1,4), customer , SUM(total),no
FROM 表  GROUP BY  MID(lot_no,1,4)

------解决方案--------------------
Java code

select substr(lot_no, 1, instr(lot_no, '#')-1) as lot_no, 
       customer, sum(total) ,no 
  from table 
  group by substr(lot_no, 1, instr(lot_no, '#')-1) ,no ,customer
