如何在mysql中为第一行选择一个唯一值，然后不显示该值，但显示所有记录？

Question

there are 2 mysql table like this

table 1

--id-----config_name
--1-----OS
--2-----Control Panel
--3-----Bandwidth

table 2

id -- config_id--- config_Option_name --- Price
1--------1-------------Windows 2008--------20.00
2--------1-------------CentOs 5----------------0.00
3--------2-------------whm/cPanel-----------30.00
4--------2-------------Plesk-------------------50.00

---

Now I want to show them like this, ONLY USING MYSQL.

1. OS
   
   Windows 2008 = 20.00
   
   CentOs 5 = 00.00
   
   
2. Control Panel
   
   whm/cPanel= 30.00
   
   Plesk = 50.00
   
   

IS THIS POSSIBLE? So now "os" or "control panel" are selected once although if we use group by or join it comes twice.

Using single SQL statement

Answer 1

Don't use SQL to format output like this. You should do it on a client side.

Anyway here is a query to do it in SQL only ( SQLFiddle demo ):

select cfgN from
(
   select concat('\t',
                 CONFIG_OPTION_NAME,
                 '=',FORMAT(Price, 2) ) as cfgN, 
                 config_id,
                 t2.ID,
                 CONFIG_OPTION_NAME,
                 Price 
   from Table2 t2
   join Table1 t1 on (t2.config_id=t1.id)

   union all

   select concat(cast(id as char),
                 '. ',CONFIG_NAME) as cfgN, 
          id config_id,
          null ID,
          CONFIG_NAME, 
          null Price 
   from table1 

) t3 order by config_id,id
