i have 2 tables: table column a-id , double field column total amount, table b foreign key column a-id , amount column. i want total amount in table change automatically, depending on field. is behavior possible implement? essentially, i'd field hold query runs every time add/delete/update row in table b. i'm using phpmyadmin (if it's relevant). i've tried using following queries: take current total amount , put them in variable named i. make changes in table b. update new total amount in table a. however, hasn't been efficient. don't that. calculate values on-the-fly in single query. need join tables that select *, a.amount + b.amount total_amount tablea inner join tableb b on a.a_id = b.a_id

i wondering if in sql request using several , statement, every , executed or triggered when previous , ok? in example : select * my_table when > 5 , b < 10 if condition > 5 not respected, test b < 10 triggered? or in java triggered when > 5 valid? thanks ;) bye ! in general, sql engines implement "short-circuiting", meaning execution of conditions stops when final value known. however, pretty unimportant. first, cannot depend on order of evaluation of conditions. so, don't know evaluated first. second, engine may use alternative execution paths (such using indexes). and, finally, short-circuiting typically has minimal impact on performance. reading data typically more important. 1 exception when 1 of conditions uses complex functions. in case, use case or subqueries ensure order of execution.

i'd create aidl service returns, lack of correct terminology, "live" objects. is, work, ifoo foo = myservice.getfoo(x); // calls myservice service ifoo ibar bar = foo.getbar(y); // ipc ifoo ibar ibaz baz = bar.getbaz(z); // ipc ibar ibaz baz.setenabled(false); // ipc ibaz modify service's copy of ibaz i expect possible, can find example. alternative like, myservice.setbazenabled(x, y, z, false); the former being more oo approach, while latter more functional. thanks. so long ifoo , ibar , , ibaz defined via aidl, should work fine.

so if have array this: var myarray = ["bmw", "toyota", "ford", "lamborghini", "ferrari", "lada"] i want display value inside array after "ford", bmw, toyota , ford doesn't show up.. how can this? using swift slice, e.g: myarray[3...myarray.count - 1] output ["lamborghini", "ferrari", "lada"] option 1 if don't know index of ford element, find using indexof method: if let index = myarray.indexof("ford") { let startindex = index + 1 let endindex = myarray.count - 1 let slice = myarray[startindex...endindex] let array = array(slice) print(array) // prints ["lamborghini", "ferrari", "lada"] } option 2 as @leo dabus pointed out, simpler method of getting section want array uses suffixfrom method: if let index = myarray.indexof("ford") { let slice = myarray.suffixfrom(index.

i scrolling section section, if scroll harshly mouse (not 1 easy scroll) or scroll harshly on laptop touchpad, shakes , down before scrolling animation starts or jumps 2 sections! is possible make scroll smoothly , 1 section (not jump 2 sections) regardless of how hard scrolls , disable scrolling while animation taking place? my code ( jsfiddle ): var isanimated = false; var nbhdlength = $('.nbhd').length; var lastsectionid = nbhdlength - 1; var allheight = (nbhdlength - 1) * window.innerheight; var = true; function setheights() { $('.nbhd').css('height', window.innerheight); } setheights(); $('html').mousewheel(function(e) { var = e.deltay > 0; if (up) { console.log('up'); = true; } else { console.log('down'); = false; // console.log(up); } if (!up && $('#id' + lastsectionid).hasclass('scrolledto') || (!up && !$('.scrol

the installation information page of pycryptodome says following under "windows (pre-compiled)" section : install pycryptodome wheel: pip install pycryptodomex to make sure works fine, run test suite: python -m cryptodome.selftest there several problems though: contrary these instructions say, not install pycryptodome wheel, rather download , try build it, resulting in error if don't have correct build environment installed c components included in package (and entire mess related biggest benefit of using wheel instead begin with). even if instead download correct wheel file pycryptodome's pypi page , must (as far know?) instead use command-line follows install it: pip install c:\some\path\name-of-wheel-file.whl this in turn makes install under default "crypto" package instead of "cryptodome" package explicitly mentioned in instructions (and therefore colliding in brea

with c++11 unique_ptr , object's lifespan seems extended outside of usual scope in following (rather contrived) example: #include <iostream> #include <memory> using namespace std; int main() { unique_ptr<char> uptr(nullptr); { char c = 'x'; cout << "c = " << c << endl; uptr.reset(&c); c = 'y'; } cout << "c = " << *uptr << endl; return 0; } output: c = x c = y the character c, released @ end of scope, survives until end of program. second output 'y', showing unique_ptr not copy value. is recommended extend lifespan of variable in way? safe, or carry same dangers reference? with c++11 unique_ptr, object's lifespan can extended outside of usual scope no, can't. the character c, released @ end of scope, survives until end of program. no doesn't, survives until end of scope, n

i have multiple enemies move toward player. trying stop them merging each other, i.e maintain type of minimum distance between each other. i'm trying (from unity3d forums): enemy1.transform.position = (enemy1.transform.position - enemy2.transform.position).normalized * distance + enemy2.transform.position; however, when have >= 3 enemies still seem bunch when apply every enemy combination. i need better method 1 not work , not scale. what around enemy prefab place quad box in effect trigger element, on script enemy set if enemy (using tag types, imagine) comes within touching of quad box run appropriate code stop enemy getting closer in , prevent enemy overlapping trigger box. your code example in question looks referencing enemy units rather instance entitites bad way of coding, you're finding, it's inflexible dealing not-specifically-named reference entities. using unityengine; using system.collections; public class exampleclass :
