Question

Hi Guys I have two tables table B has a many to 1 relationship with table A

TableA        TableB
id  name       id   value
1  basketA     1    10
2  basketB     1    5 
               1    7
               2    7
               2    3

etc..
now
$query = $this->db->get(‘TableA’);
return $query->result_array();

returns the A fields obviously but how can I do a join so it will return A-Field along with the sum of the B-Items for that field?

eg. in the result array

BasketA 22
BasketB 10

Thanks in advance!

try this:

select A.id,A.name,SUM(B.value)
from    TableA A join tableB B
on A.id=B.id
group by A.id,A.name
