MySQL sum two values different tables -


first of all, excuse me may have seen question before, i've tried solutions around here. it's not matching need. have 2 tables. 1 of them sales section agents, other technical support agents. need sum values of received calls in both sections per day.

my table structure , sample data:

enter image description here [enter image description here

example : date column remain is, received column = sales.received + tech.received , sales.answered + tech.answered came through :

select        (select sum(`received_calls`) sales) + (select sum(`received_calls`) tech     ) dual

but it's showing total only.. without showing daily calculation every day.

expected outcome:

--------------------------------------------- date       | received | answered | abandoned --------------------------------------------- |2014-11-14|   8406   |   8363   |    43 |2014-11-15|   9909   |   9792   |    116 ---------------------------------------------

and there no dates available on table without other, every day's date available on both tables no exceptions.

any help? :)

assuming dates unique (per table), can join according , add appropriate values:

select s.`date`,         s.received_calls + t.received_calls received,        s.answered_calls + t.answered_calls answered,        s.abandoned_calls + t.abandoned_calls abandoned   sales s join   tech t on s.`date` = t.`date`
