mysql - Yii2 activeRecord multiple sums from multiple join tables -


is possible, activerecord query builder multiple sums when joining multiple tables?

the query looks this:

        $po = purchaseorder::find() //todo groupby multiple sums possible?             ->select([                 'po.*',                 'sum(pi.invoice_units) invoicedunits',                 'sum(ar.received_units) receivedarticles'             ])             ->from('purchase_order po')             ->joinwith('invoice')             ->joinwith('articlesreceived')             ->where(['po.id' => 3960])             ->groupby(['po.id'])             ->one();

the result expeting :

sum(pi.invoice_units) = 234 + 2 = 236; sum(ar.received_units) = 10 + 6 = 16;

however this: 236*2 = 472; 16*2 = 32;

is possible multiple sums way? in normal sql, join , sum inside join, how in activerecord?

this correct query returns right sums:

select po.*, ars.receivedarticles, pis.invoicedunits purchase_order po     left join (select ar.purchase_order_id, sum(ar.received_units) receivedarticles purchase_articles_received ar group ar.purchase_order_id) ars on po.id = ars.purchase_order_id     left join (select pi.order_id, sum(pi.invoice_units) invoicedunits purchase_invoice pi group pi.order_id) pis on po.id = pis.order_id     po.id = 3960 group po.id;

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
