mysql - TIMEDIFF Subquery returns more than 1 row in mariadb -


having issue specific section of query using timediff , addtime:

i want result :

| waktuhilang | |-------------| |    04:00:00 | |    03:00:00 |  select addtime(     (         select             sec_to_time(                 sum(                     time_to_sec(                         maketime(                             durasi + 0,                             substring_index(durasi, 'jam ', - 1) + 0,                             0                         )                     )                 )             ) waktudw                     trans_lhpdtdw     ),     (         select             timediff(jammasuk, jammulai) lamaistirahat                     trans_lhphd     ) ) waktuhilang

i've seen people mentioning using in instead of = within subquery, can't seem work. ideas out there? thanks

i have 2 tables :

table trans_lhpdtdw table trans_lhphd

create table `trans_lhpdtdw` (   `idbukti` int(11) not null,   `partid` varchar(50) not null,   `typedowntime` varchar(50) not null,   `durasi` varchar(50) not null,   `keterangandowntime` longtext not null  ) engine=innodb default charset=latin1;  -- ---------------------------- -- records of trans_lhpdtdw -- ---------------------------- insert `trans_lhpdtdw` values ('2', 'blap-fg150-kt-kgx', 'setting mold', '1 jam 0 menit', 'ass'); insert `trans_lhpdtdw` values ('1', 'blap-fg152-pf-kgx', 'tidak ada fasilitas', '1 jam 0 menit', 'as'); insert `trans_lhpdtdw` values ('1', 'awdx-fg002-hn-kgx', 'tidak ada job', '2 jam 0 menit', 'sasa');  create table `trans_lhphd` (   `idbukti` int(11) not null auto_increment,   `nobukti` varchar(1000) not null,   `periode` int(6) not null,   `tanggal` date not null,   `divisi` varchar(50) not null,   `jamkerja` varchar(10) not null,   `jamproduksi` time not null,   `jamselesai` time not null,   `jammulai` time not null,   `jammasuk` time not null,   `idmesin` varchar(50) not null,   `lineid` varchar(50) not null,   `operator` int(5) not null,   `planning` decimal(18,0) not null,   `tambahan` varchar(50) default null,   primary key (`idbukti`),   key `idbukti` (`idbukti`),   key `idbukti_2` (`idbukti`) ) engine=innodb auto_increment=3 default charset=latin1;  -- ---------------------------- -- records of trans_lhphd -- ---------------------------- insert `trans_lhphd` values ('1', 'lhp/201708/00001', '201708', '2017-08-24', 'all divisi import (non ppic)', 'shift i', '01:05:00', '09:05:00', '01:00:00', '02:00:00', 'bh 260k', 'l3002', '1', '213', '1 jam 15 menit'); insert `trans_lhphd` values ('2', 'lhp/201708/00002', '201708', '2017-08-17', 'injection', 'shift i', '07:00:00', '16:00:00', '11:25:00', '13:25:00', 'bh 260k', 'l2002', '100', '1000', '');

an approach providing 1 row each idbukti

query:

select    d.idbukti, addtime(w.waktudw, timediff(d.jammasuk, d.jammulai)) waktuhilang trans_lhphd d inner join (            select idbukti, sec_to_time(sum(time_to_sec(maketime(durasi + 0, substring_index(durasi, 'jam ', - 1) + 0, 0)))) waktudw            trans_lhpdtdw            group idbukti            ) w on d.idbukti = w.idbukti

results:

| idbukti | waktuhilang | |---------|-------------| |       1 |    04:00:00 | |       2 |    03:00:00 |

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
