in sql developer created table bill (id,nr,cost,days,total -all integers) and need create constraint (or trigger -what best) act if nr > 10 total = total -5 (total = nr * cost * days ). create or replace trigger discount after insert or update on bill update bill set total = nr * cost * nr - 5; when (nr_slide > 10 ) can use update inside triggers? constraint can prevent putting wrong value table. if use constraint, need calculate correct value total , insert table, otherwise no rows inserted. means need trigger. create or replace trigger discount after insert or update on bill each row -- added here begin if :new.nr > 10 :new.total = :new.nr * :new.cost * :new.days - 5; end if; end; if educational project - no problem (of course, problem - quite bad example education). in applications real life use advise of ash burlaczenko.

i've activity contains login fragment , activity b contains home fragment. i've start b login fragment after succesfully login request (async). i've callback listener inside login fragment: onsuccess(result) { startactivity(b); } today met nice bug: getting exception "illegalstateexception: can not perform action after onsaveinstancestate" . i think that's not bug, anyway don't know how workaround that. this blog post suggests avoid transaction inside async callback methods, yeah how? commitallowingstateloss() should used last resort: in case, should use inside home fragment transaction in activity b creation method? basically, should start activity after async callback? you should use onpostexecute(result) in asynctask: private class logintask extends asynctask<parameters,...> { ... protected void onpostexecute(long result) { //if result successful start activityb } } onpost fires after asynctask complete....

objective: generate random integer (from 1-99) , use numbers.dat file (from last lab) determine if generated random number in file. not count number of times find random number, output it’s in file or not in file. possible pseudo-code: generate random # 1-99 declare , initialize boolean variable false loop until end of file or match found: read number. compare numbers. if match, set boolean var true if boolean true number found else not found. part 2. put code in part 1 inside for-loop part 1 runs 3 times. b. output – similar output below: the random number 35 in file. random number 10 not in file. random number 9 in file. my code: import java.util.*; import java.io.*; public class randomnumbermatch { public static void main(string[] args) throws exception { scanner num = new scanner (new file ("numbers.dat")); random ran = new random(); while(num.hasnext()) { int number = num.nextint(); int x = ran.n...

i'm trying create circular uibutton in xcode setting corner radius equal half button width. problem is, storyboard says width of button 200 , reports 46.0 when access in uiviewcontroller . i've tried getting width using button.bounds.size.width , button.frame.size.width , button.layer.frame.size.width , , button.bounds.width , they're same. the crazy thing didn't have trouble after created test project , added big button. major difference think of project used auto layout, adding width constraint didn't change anything. for reference, i'm using xcode 6.1, swift, , it's iphone-only app targeting ios 8. your button ending 46 points wide @ runtime, want 200 points? make sure 200 pt width constraint on button high priority, dial compression resistance , dial down content hugging (i'm assuming content naturally make smaller size seeing).

when programming c++ in visual studio, insists on giving me these god-awful indendations on access modifiers - condolences if likes them way ;) (a joke folks!) public class myclass { public: myclass(); ~myclass(); int wowanint(); } needless say, want this: public class myclass { public: myclass(); ~myclass(); int wowanint(); } is there way achieve using (i've got resharper , highlighter) or perhaps vanilla vs? the closest can built-in visual studio editor settings change indenting mode "smart" "block" (tools -> options -> text editor -> c/c++ -> tabs -> indenting). when this, can indent like, lose "automatic indenting." basically, whenever press [enter] new line indented same number of tab stops / spaces previous line , won't automatically reformat lines them line up.

i working on unit test of instance method. method happens asp.net mvc 4 controller action, don't think matters much. found bug in method, , i'd use tdd fix bug , make sure doesn't come back. the method under test calls service returns object. calls internal method passing string property of object. bug under circumstances, service returns null, causing method under test throw nullreferenceexception. the controller uses dependency injection, have been able mock service client have return null object. problem want change method under test when service returns null, internal method should called default string value. the way think use mock class under test. want able assert, or verify internal method has been called correct default value. when try this, mockexception stating invocation not performed on mock. yet able debug code , see internal method being called, correct parameters. what's right way prove method under test calls method passing particular para...

if (operation = '+' || operation = '-' || operation = '*' || operation = '/' || operation = '%')//error line { printf("enter first operand:\t\t"); getchar(); scanf("%d", &num1); printf("enter second operand:\t\t"); getchar(); scanf("%d", &num2); } it gives out error saying : error: expresion must modifiable value it gives me error on if line , on of arguments 1 says operation = '%' what problem ?? thank guys :) you made typo , instead of comparison operator == wrote assignment operator = instead of if (operation = '+' || operation = '-' || operation = '*' || operation = '/' || operation = '%') there must be if (operation == '+' || operation == '-' || operation == '*' || operation == '/' || operation == '%') you write if statemen...

i'm not quite understanding solution found here: selecting values oracle table variable / array? i have list of table names. loop thru them array, using values tables search from. tmp_dormant_filters physical table of table names. array below same list. lm_dormant_email list of email addresses. i want check existence of dormant email addresses in list of tables. realize write same query 12 times search each table. that's not going improve sql skills. here array attempt. in attempt, oracle doesn't way i'm calling array value in not exists sql: declare type array_t varray(12) of varchar2(25); array array_t := array_t('bt_abandoned_hist', 'bt_browsed_hist', 'bt_purchased_hist', 'cm_abandoned_hist', 'cm_browsed_hist', 'cm_purchased_hist', 'cm_page_views_hist', 'mb_abandoned_hist', 'mb_browsed_hist', 'mb_carted_hist', 'mb_page_views_hist', 'mb_purchased_hist'...
