i trying delete table( mytable ) has foreign key reference linking 4 other tables. i needed delete data mytable referenced table1 , table2 , not table3 , table4 . have deleted data in table1 , table2 i tried this: delete mytable id not in(select mytableid table1) delete mytable id not in(select mytableid table2) but doesn't work because if did inadvertently delete data table2 references. is there way delete table fks aren't being referenced tables? (rewritten answer sql server syntax after basic research , finding the delete statement in sql server .) use multiple table syntax of delete statement. delete mytable mytable left join table1 on mytable.id = table1.mytableid left join table2 on mytable.id = table2.mytableid left join table3 on mytable.id = table3.mytableid left join table4 on mytable.id = table4.mytableid (table1.mytableid not null or table2.mytableid not null) , table3.mytableid null , table4.mytableid null the

you're given array of n integer numbers. maximal sum of array maximal sum of elements of nonempty consecutive subarray of array. example, maximal sum of array [1, -2, 3, -2, 5] 6 because sum of subarray [3, -2, 5] 6 , impossible achieve greater subarray sum. you're allowed remove no more 1 element given array. maximal possible maximal sum of resulting array can achieve doing so? i testing code own test cases. getting correct output on dev-c++. when test code online wrong answer. not able find out problem. #include <stdio.h> #include <limits.h> #include <stdlib.h> struct result{ long long int start; long long int end; long long int sum; }res; long long int find_max(long long int a[],long long int n) { long long int max=llong_min; long long int i; for(i=0;i<n;++i) { if(a[i]>max) max=a[i]; } return max; } long long int max_sub(long long int a[],long long int n) { long long int

okay, i'm new node, , using node server serve static js, can't find info on anywhere. i'm running application ember app kit , gets built node server.js deploy, , heroku runs node server.js . it uses grunt building, testing, etc. i'd know how can specify configuration variables (i.e. authentication tokens) can overridden heroku config variables. the closest i've been able custom task reads environment variables , writes out json file gets built site (and assigned global var). works locally, doesn't take account heroku configs. i wrote deploy script gets heroku's configs, exports them environment variables locally, , build--which works , configs updated on app deploy . if heroku config:add config_test=test_value , app doesn't see value config_test until next time deploy app. i'd app start embedding config value in browser js immediately. any way node way app set up? i not sure understand what's wrong taking config var

i have questions w.r.t. ip header. if correct, total length field shows length of overall packet. internet header length (ihl) shows length of header , whether options set or not. my question why ihl field needed if there total length field shows total length? regards with ipv4, header length variable. ihl pointer start of packet payload. without this, unable know payload starts. ipv6 has fixed header size, ihl unnecessary, , doesn't exist.

personally, i've thought goal provide good ux every user, regardless of browser's features , modernity. this doesn't equate identical page renderings , functionality , though. at work i'm being asked make sure pages render identically in every browser, means either dumbing down design not use newest features, or loading ton of polyfills in legacy browsers achieve "browser transparency," far see, hurts ux because have longer page loads styles , features don't affect page's usability. taken extreme, result mean design should cater lowest common denominator no js (some people don't use js) , features beyond should excluded in name of uniformity. am wrong in thinking identical ux should not goal, rather good, consistent ux best capabilities of browser? when developing multiple browsers, cannot provide identical experience every browser. after all, try access site via lynx, , you're not going design ux ensure using lynx have ide
