i want insert row in table. problem how values 2 different tables tables. itable has 3 columns ( studentphoto , studentname , studentid ) dtable has (studentphoto , studentid ) ltable have (studentname, studentid) i want insert data table itable table dtable , ltable . is possible , if yes, how? try insert itable (studentphoto , studentname , studentid) select d.studentphoto,l.studentname,d.studentid dtable d inner join l ltable on d.studentid= l.studentid

this has super simpel solutions, can't wrap head around it. i have sql query: select traning.type_name,users.user_id, users.user_name,user_traning.min_puls, user_traning.medel_puls,user_traning.max_puls, user_traning.duration,user_traning.date, user_traning.view traning inner join user_traning on traning.tr_id=user_traning.tr_id inner join users on user_traning.user_id=users.user_id order `user_traning`.`date` desc i have colum in user_traning called view . the input form inputs either null or 2 . im thinking null means view input, , 2 user want hide input. i have been trying way: while($row = $users_traning->fetchobject()) { if($row->user_id == $_session['user_id'] && $row->view == null) { echo '<span class="glyphicon glyphicon-user"></span> <a href="userinfo.php='.$row->user_id.'">you </a> have ' .$row->type_n

i have set push notification app via parse.com. app installed on iphone 5s running ios8.2. app code in swift if send regular push notification, comes fine, plays short buzz (like 'quick' vibration or short standard 'note' text alert, rather have set standard text alert.

i have 2 threads: primary thread main processing of application, , secondary thread receives data batches primary thread , processes , outputs them, either user, file, or on network. in general, data should processed @ faster rate produced. ensure main thread never waits secondary thread. secondary thread can accept amount of overhead, expanding buffers, redoing work, , on, sole objective of maximizing performance of main thread. ideally main thread never synchronize @ all. there way push synchronization costs onto 1 thread in java? this outline of solution: the main thread works in isolation time, piling data collection; when has generated nice batch, it: i. creates new collection itself; ii. sets filled-up collection aside, available picked reading thread; iii. cases collection atomicreference . the reading thread polls atomicreference updates; when notices has been set, picks batch, casing null shared reference, main thread knows can put collection in.

this question has answer here: is good/acceptable practice declare variable interface type? 5 answers what mean “program interface”? 30 answers i have next question. have interface public interface myinterface { blah blah } and have child: public class mychild implemets myinterface { blah blah } what difference between: mychild child = new mychild(); and myinterface child = new mychild(); ? your added code snippet - mychild child = new mychild(); and myinterface child = new mychild(); in first case child can contain object of mychild class. in second case child (where child myinterface ) can contain object of class implements myinterface . here can advantage of polymorphism.

i have following code executing inside controller in sailsjs. underlying adapter sails-orientdb. following error back typeerror: cannot call method 'then' of undefined why error occurring? user.query("select id user username='" + req.param("userid") + "'").then(function(userdata){ console.log(userdata); return userdata; }).fail(function (err) { console.log("handled"); }); to expand on @jaumard said. background usually it's recommend use standard waterline query methods such find() , update() , create() , destroy() , etc. these methods support callbacks , promises , these methods work same way against waterline adapter (orientdb, mysql, mongodb, etc). sometimes may want more complex not supported standard waterline methods , sails-orientdb extends waterline definition query() , among other methods . sails-orientdb .query() sails-orientdb query uses callback c

due project setup (same flasky ) , when run python tests ( line 34 ), connection development database created, before configuration set test (line 11 here ). results in problems tests, since meant run on clean db. looking online, found descriptions of switch_db not need. need either change database connection using, or drop connection , create new one. cant find way either of these.. missing ? connection initialized using line of code, inside init .py of main app directory. from mongoengine import connection db_name = 'name_from_config' connection(db_name) you should avoid creating connection mongoengine in way describe precisely reason. flasky using application factory approach allows application know connection config use when implementing data models. the best way integrate mongoenigne app flask-mongoengine should solve problem out-of-the-box.
