I have a table like this:

ref_num   name      type       route
----------------------------------------
1         A         W          401
2         B         X          401
3         C         E          401
3         C         E          411
4         D         Z          401
5         K         W          701
5         K         W          991
5         K         W          556
5         K         W          401
6         L         X          401
7         D         Y          401
7         D         Y          411
7         D         Y          680
8         E         Z          401

And i want a RESULT like this:

ref_num   name      type       routes
----------------------------------------
1         A         W          401
2         B         X          401
3         C         E          401,411
4         D         Z          401
5         K         W          701,991,556,401
6         L         X          401
7         D         Y          401,411,680
8         E         Z          401

If anybody can give me a query example to get the desired result it would be greatly appreciated

Answer 1

select ref_num, name, type, group_concat(routes)
from your_table
group by ref_num

In MySQL you don’t have to group by all values you are selecting. Other values will probably selected by random. But if the other values are the same in one group then you don’t have to worry. That is the case in the OP’s question.
