Select id[Orders], order_id[items], name[items]1, name[items]2, name[items]3...
Suggestions Pls...

Answer 1

It seems that you only need to access table items to get what you need.
SELECT order_id, GROUP_CONCAT( name SEPARATOR ', ') item_names
FROM items
GROUP BY order_id;

Answer 2

I get solution for only known number of fields....
Row to Column:
STEP : 1
select #orderID:=order_id,
#name:=GROUP_CONCAT(name) item_names,
#price:=GROUP_CONCAT(price) item_price
from item group by order_id limit 1;
OUTPUT :
+----------+-------------------------+------------------+
| order_id | item_names | item_price |
+----------+-------------------------+------------------+
| 1 | Mobile1,Mobile2,Mobile3 | 25000,30000,6500 |
+----------+-------------------------+------------------+
STEP : 2
select #orderID,
SUBSTRING_INDEX(SUBSTRING_INDEX(#name, ',', 1),',',-1) as Name1,
SUBSTRING_INDEX(SUBSTRING_INDEX(#price, ',', 1),',',-1) as Price1,
SUBSTRING_INDEX(SUBSTRING_INDEX(#name, ',', 2),',',-1) as Name2,
SUBSTRING_INDEX(SUBSTRING_INDEX(#price, ',', 2),',',-1) as Price2,
SUBSTRING_INDEX(SUBSTRING_INDEX(#name, ',', 3),',',-1) as Name3,
SUBSTRING_INDEX(SUBSTRING_INDEX(#price, ',', 3),',',-1) as Price3;
OUTPUT :
+----------+---------+--------+---------+--------+---------+--------+
| #orderID | Name1 | Price1 | Name2 | Price2 | Name3 | Price3 |
+----------+---------+--------+---------+--------+---------+--------+
| 1 | Mobile1 | 25000 | Mobile2 | 30000 | Mobile3 | 6500 |
+----------+---------+--------+---------+--------+---------+--------+
