so trying learn how store pgsql queries on google map. database contains 2 json columns lat/long. have slightest idea of how query json pgsql , display on google maps. can give me tutorials or can give me insight on getting done? the usual way choose "backend" programming language, python, php , write little program on web server apache, connects database , queries data when browser asks it. you should have "user interface" part, html/css/javascript displays in browser. there many such projects, can use google, github find open source projects it, or use stackoverflow find answers specific parts of it.

i have model, called user (derived database) , i'm adding methods inside partial class, allowing user object maintenance type work. as example, application update user's supervisorid in database in alignment database: public partial class user { databaseentities db = new databaseentities(); otherentities otherdb = new commonentities(); public void updatesupervisor() { // lookup supervisor's username in other database: string supervisorusername = (from x in otherdb.vwemployees join y in otherdb.vwemployees on x.supervisor_eid equals y.employee_id x.user_id == searchusername select y.user_id).firstordefault(); // update database record supervisor of staff member: this.supervisoruserid = (from x in db.users x.adusername == supervisorusername ...

i have created form requires user input information on fields , submit form. goal user input , insert new records on database. current challenges since used loop in php create table/form: i can not access input $_post not sure how go differentiating of rows , inputs each other (since used loop create them). thinking array... please see screenshot of form working with. below have submit button. if (isset($_post['submit'])) { $date = date('m\/d\/y'); $ordnum = $_post['cpordernumber']; $ponum = $_post['cpponumber'] . $_post['cpponumberf']; $palnum = $_post['palnum']; $casecount = $_post['casecount']; $cpsflot = $_post['cpsflot']; $sscc = $_post['sscc']; if(!empty($_post['cpordernumber']) || !empty($_post['cpponumber'])) { require_once('mydatabase.php'); $query = "insert asn (date, ordnum, ponum, palnum, casecoun...

in sql server, 1 way of getting number of rows in table is select count(*) mytable but assume that's o(n) time n number of rows. there metadata can access has number of rows stored? yes, can use sys.partitions , might not exact number, it's extremely fast: select sum(rows) sys.partitions [object_id] = object_id('dbo.mytable') , index_id in (0,1);

i want solve following optimisation problem in matlab: min sum(abs(x)) s.t. a*x = 0, lb <= x <= ub where x dense vector, sparse matrix, lb , ub real lower , upper bounds respectively. convenient function linprog() or lp solver gurobi. know how formulate problem? thanks the objective minimize sum(abs(x)) can translated to: minimize sum(u) s.t. -u_i <= x_i <= u_i (where dim(x) == dim(u) )

i attempting run package after installing it, getting error: importerror: /home/brownc/anaconda3/lib/python3.5/site-packages/dawg.cpython-35m-x86_64-linux-gnu.so: undefined symbol: _ztvnst7__cxx1118basic_stringstreamicst11char_traitsicesaiceee the dawg....gnu.so file binary , doesn't give information when opened in sublime. don't know enough binary files in order go in , remove line or fix it. there simple fix not aware of? i found answer specific case, may run case well: i using anaconda (python 3 version) , installing package conda install -c package package worked instead of pip install package . i hope helps someone.

similarly __author__ or __version__ top level module variables, there convention specifying supported python versions python source file? my usecase project has scripts need compatible python 2.4. note fact in them in universally recognizable way. i not asking how require minimal python version during execution . problem developers may accidentally use feature not compatible python version particular script needs support. pycharm can warn python incompatibilities. great if pick annotation , configure warning on per-file basis. there's no convention know of specifying supported python versions in python source file. if you're making python library , distributing via pypi (and pip ), can add package metadata says versions of python it's compatible with. for example, scandir module, can see on pypi it's (currently) marked compatible python 2.6, 2.7, , 3.2-3.5. metadata lives in classifiers keyword in package's setup.py : setup( name='sc...
