Question

my question title may not really describe my problem sorry for that. I am undertaking database module. Thus, my sql query must be complicated and able to do in a single query

I have two table one is category

• catid int
• catname varchar

another table is product

• productid int
• catid references category(catid)
• productname

now i want to do a select statement which select catname + an array of products under that cat, is it possible to do this in a single query like

SELECT a.catname,(b.productname bla bla in an array)
from category a, product b WHERE a.catid=b.catid

i dont know if this is possible, if yes please help me

Answer 1

MySQL – use GROUP_CONCAT

SELECT a.catname, group_concat(b.productname) productnames
from category a
inner join product b on a.catid=b.catid
group by a.catname
