Выборка из двух таблиц

Recommended Posts

Добрый день.

Есть две таблицы:
table_1

id       quantity     mydate

1         20             2020-04-03

2       10              2020-04-03

 

table_2

id       title       price       op_date

1       k            100         2020-03-20

2      p           20           2020-03-29

3      s          20           2020-04-03

 

что хочу  - выбрать данные из table_2 и добавить данными из table_1 (если есть)

SELECT  tt.title, tt.price, tt.op_date, SUM(td.quantity) AS total

FROM table_2 tt

LEFT JOIN table_1 td ON (tt.op_date = td.mydate)

 

но в результате получаю только одну запись. Не все записи из table_2 и часть из table_1, а только одну запись.....
Подскажите где тупость пишу.....
