MySQL/PHP merge rows by row values -


i need little mysql select in sql or php. situation: have sql table this

id | organization_id | investment | investment_curr | paid | paid_curr | effective_from | effective_to 1 | 195001 | 5000 | eur | null | eur | 2010-06-23 | null 2 | 195001 | null | eur | 5000 | eur | 2010-06-23 | null 3 | 195001 | 2000 | skk | null | skk | 2007-08-01 | 2010-06-22 4 | 195001 | null | skk | 2000 | skk | 2007-08-01 | 2010-06-22

now have php select (joomla), when select values organization_id

$query_rpo_organization_equity_entries = $db->getquery(true); $query_rpo_organization_equity_entries     ->select(array('organization_id',                                     'investment_amount',                                     'investment_currency',                                     'paid_amount',                                     'paid_currency',                                     'effective_from',                                     'effective_to'     ))     ->from($db->quotename('rpo_organization_equity_entries'))     ->where($db->quotename('organization_id') . ' = '. $db->quote($rpo_id))     ->order(($db->quotename('effective_to') . ' not null'), $db->quotename('effective_to') . ' desc '); $db->setquery($query_rpo_organization_equity_entries); $query_rpo_organization_equity_entries = $db->loadobjectlist();

then im calling foreach

foreach($query_rpo_organization_equity_entries $rpo_organization_equity_entries) {}

everything works right, not way need it. foreach returns 4 arrays, need merge/combine rows columns "effective_from" , "effective_to" (if have same values. , organization_id ofcourse). combine row ids 1 , 2, , rows ids 3 , 4, , instead of 4 arrays have 2 combine/merge arrays this

xy | 195001 | 5000 | eur | 5000 | eur | 2010-06-23 | null xy | 195001 | 2000 | skk | 2000 | skk | 2007-08-01 | 2010-06-22

how should it? better solve sql , in php?

thx

the result wish can achieved mysql using group by function.

in joomla docs pretty clear on one. van use group() function on object.

//example $query ->select( array('catid', 'count(*)') ) ->from($db->quotename('#__content')) ->group($db->quotename('catid'));

in case want change code like:

$query_rpo_organization_equity_entries = $db->getquery(true); $query_rpo_organization_equity_entries     ->select(array('organization_id',                                     'max(investment_amount)',                                     'investment_currency',                                     'max(paid_amount)',                                     'paid_currency',                                     'max(effective_from)',                                     'max(effective_to)'     ))     ->from($db->quotename('rpo_organization_equity_entries'))     ->where($db->quotename('organization_id') . ' = '. $db->quote($rpo_id))     ->group('`organization_id`, `effective_from`, `effective_to`') //this 1     ->order(($db->quotename('effective_to') . ' not null'), $db->quotename('effective_to') . ' desc '); $db->setquery($query_rpo_organization_equity_entries); $query_rpo_organization_equity_entries = $db->loadobjectlist();

i have not tested in lines of should work.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
