i'm aware if you're inserting variable, use mysqli_real_escape_string. but, if i'm inserting fixed value not variable, need use function? for example, syntax below. insert name variable, , value '1' status column. safe avoid sql injection column status? since not variable. "insert customer(name, status) values ('".mysqli_real_escape_string($conn, $name) ."', '1')"; when using mysqli, safest use prepared statements: $stmt=$mysqli->prepare("insert customer(name, status) values (?, '1')"; $stmt->bind_param("s", $name); (see http://php.net/manual/en/mysqli.quickstart.prepared-statements.php more detailed , working code). in can leave static values is, nobody can replace those. can alter table: alter table customer alter column status default '1'; then not have set longer.

for background, playing through untrusted , javascript-based programming game core mechanic editing code modify game world progress forward. have solved levels "intended" way modifying variables given in local scope using documented in-game api. however, wondering if there "unintended" ways modify game state/game definition fishing around. a lot of game has code follows (evaluated in window scope): function foo() { var bar = 1234; } i understand can access foo scope referring window.foo . there way can access bar inside foo though not explicitly exposed? to clarify, above code evaluated me (in window scope, believe, can @ least reference foo ). can not change evaluated. (i suppose redefine foo if wanted, , bypass lot of restrictions, that's tangential current direction of questioning.) rather, goal is, given has been evaluated, modify in place (such setting new value bar ). thanks in advance! the short answer no . it's not

i new prolog , although i’ve read books can tell programming brain can’t think prolog way. problem solve pretty simple (i believe). describe via example. let’s have graph contains 4 “types” of nodes , 3 edges connect nodes. types can a, b, c or d , can see image below (see figure 1), can connected b , c (a_to_b , a_to_c edges respectively), while c can connected d (c_to_d edge). there’s additional rule not shown on picture: can connected @ 1 c. i express these simple rules in prolog solve problem shown in second picture. there 3 nodes type missing (labeled x?, y? , z?). applying above rules in mind can find x? , z? of b type (as can connect no more 1 cs) , y? of type d c can connect d. could please provide me on that? not writing pick solution. learn prolog suggestion on book explains prolog people have never worked on such concepts before me welcome. edit: example fails i came following 2 examples: for example 1, rules are can_connect(a,b,_). can_connect(a,c,

i have java program connected mysql database jdbc in introduce datetimes. many times year introduced assigning 00 days , months not specified, instance 1700-00-00 year 1700. when try date resultset using resultset.getdate().tostring() proper date specified dates in case of partial dates get: previous_year-11-30, 1699-11-30 year 1700. when try resultset.getdate().gettime() equivalent result: -8520339600000 . resultset.gettimestamp() gives same results. conversely, when datetime mysql proper value 1700-00-00 . i have tried different years obtaining same results. appreciated. here how fetch data (this 1 method, many other similar , give same results): public naixement(int fill) throws dbexception{ super(); try { string str = "select * naixement id_fill=?"; preparedstatement pst = con.preparestatement(str); pst.setint(1, fill); resultset rs = pst.executequery(); if (rs.next()){

i have tables a, b, c. has nullable fk b called bid , b has fk c cascade delete. when c deleted, need bid on set null. when delete on c cascades b, expect following trigger execute: create trigger after_delete_b on b delete begin declare @bid int select @bid = id deleted update set bid = null bid = @bid end however seems execute , not others. cannot figure out why. your trigger not handling multiple row deletes, captures 1 id deleted rows , update related value in table a, since there 1 variable, you need use set based approach handle multiple deletes. for need modify trigger definition this..... create trigger after_delete_b on b delete begin set nocount on; update set a.bid = null inner join deleted d on a.bid = d.id end

i able start hadoop cluster in docker, distributing hadoop nodes different physical nodes, using swarm . i have found sequenceiq image lets me run hadoop in docker container, doesn't allow me use multiple nodes. have looked @ cloudbreak project, seems need openstack installation, seems bit overkill, because seems me swarm alone should enough need. also found this stackoverflow question+answer relies on weave, needs sudo-rights, our admin won't give everyone. is there solution starting hadoop cluster comes down starting few containers via swarm? i cannot give definitive answer, if looking set without administratrator privileges , answers to question fail fear might out of luck. consider asking admin why not want give out sudo access, chances either can take away doubts, or else turns out want undesirable.

using vbscript 5.5 regex, how can replace string there's space after every 4 characters? i tried following doesn't work: dim rex new regexp rex.ignorecase = true rex.global = true rex.pattern = ".{4}" dim newstring string newstring = trim$(rex.replace(trim$(inputstring), "$0 ")) you need group () , better ref ($1): >> set r = new regexp >> r.global = true >> r.pattern = "(.{4})" >> wscript.echo r.replace("1234567890123", "$1 ") >> 1234 5678 9012 3 >>

i want deploy codeigniter on laravel forge platform, because love simplicity , auto-deploy nature of platform. how do it? this how did it, , problems had doing it. problem 1 because forge runs on nginx, not apache, apache php directives ignored. (i think). so, main problem had short_open_tag directive in default configuration set 'off', meaning php fpm configuration problem 2 in nginx configuration file specific site (not server) replace try_files $uri $uri/ /index.php?$query_string; with try_files $uri $uri/ /index.php;

i have variable has string recieves strange characters hearts. besides point, wanted know anyhow: how leave string letters , numbers, discarding rest or replacing nothing (not adding space or anything) my first thought using regular expression wanted know if powershell had more native automatically. let have variable this: $temp = '^gdf35#&fhd^^h%(@$!%sdgjhsvkushdv' you can use -replace method replace non-word characters this: $temp -replace "\w" the result be: gdf35fhdhsdgjhsvkushdv

i have 2 question ist 1 how take backup of tables , schedule through pt 8.49 ps_query , 2nd how schedule backup client side through cron jobs.my backup script datamover using taking manual backup are:- set no trace; set log d:\backup_prod\backup_6tables_28 july2015 cu.log; set output d:\backup_prod\backup_6tables_28 july2015cu.dat; "adm appl tbls" export adm_appl_prog emplid 'uf15%'; export adm_appl_plan emplid 'uf15%' ; export adm_appl_sbplan emplid 'uf15%' ; export adm_app_car_seq emplid 'uf15%' ; export adm_appl_data emplid like'uf15%' ; export ps_sad_std_app_nld emplid 'uf15%' ; you can execute dms scripts via command line. create script executes via schedule whichever operating system on. example: psdmtx -ct dbtype [-cs server] -cd database_name -co user_id -cp user_password[-ci connect_id -cw connect_password] [-i process_instance] -fp dms_filepath
