php - Basic SQL query design issue -


i'm trying create query equivelant of (does not work).

select * `categories` c , select * `items` , select count(i.id) items , select sum(i.price) price; 

i not using sqlserver, , i'm using pdo through php database connectivity.

here's tables.

category

+----+------------+ | id |  category  | +----+------------+ |  1 | first_cat  | |  2 | second_cat | +----+------------+ 

items

+----+----------+------+-------+ | id | category | name | price | +----+----------+------+-------+ |  1 |        1 | foo  | 1.99  | |  2 |        1 | bar  | 2.00  | |  3 |        2 | oof  | 0.99  | |  4 |        2 | rab  | 1.99  | +----+----------+------+-------+ 

based on these tables expecting these query results:

+----+------------+-------+-------+--+ | id |  category  | items | price |  | +----+------------+-------+-------+--+ |  1 | first_cat  |     2 | 3.99  |  | |  2 | second_cat |     2 | 2.98  |  | +----+------------+-------+-------+--+ 

any help?

the query have posted in comment not joining category table , item table. makes me think this?:

select      categories.id,     categories.category,     count(*) items,     sum(items.price) price      `categories`     join items         on categories.id = items.category group     categories.id,     categories.category
