sql - How to JOIN two tables on behalf of Max date -


i have tried following. query working returning more rows not expected.

  select x,y,z      (select (t1.hour*4) + int (t1.minuts/15 ) +1 x,t1.amount y, t1.date,t2.amount z table1 t1      inner join      (select * table2 date=(select max(date) table2 ))as t2     on t1.store=t2.store     t1.date = (select max(date) table1 ))  

sample data:=

store   date    day_of_wk   hour    minuts  amount 574     13-03-2017  2         0      0       0.00 574     13-03-2017  2         0      15      0.00 574     12-03-2017  2         0      30      0.00 574     11-03-2017  2         0      45      0.00 574     11-03-2017  2         1      0       0.00 574     13-03-2017  2         1      15      0.00 

both table having same data there different business logic on amount column.

what need amount , time id both tables of max date.

solved following query=>

select t1.id x,y,z  (select (hc.hour * 4) + int (hc.minuts/15 ) + 1 id, amount y, date table1 hc date = (select max(date) table1))t1 left join (select (hs.hour * 4) + int (hs.minuts/15 ) + 1 id, amount z, date table2 hs date=(select max(date) table2 ))t2 on t1.id=t2.id
