sql server has ability declare variable, call variable in query so: declare @startdate date; set @startdate = '2015-01-01'; select * orders orderdate >= @startdate; does functionality work in amazon's redshift? documentation , looks declare used solely cursors. set looks function looking for, when attempt use that, error. set session startdate = '2015-01-01'; [error code: 500310, sql state: 42704] [amazon](500310) invalid operation: unrecognized configuration parameter "startdate"; is possible in redshift ? no, amazon redshift not have concept of variables. redshift presents postgresql, highly modified. there mention of user defined functions @ 2014 aws re:invent conference, might meet of needs. update in 2016: scalar user defined functions can perform computations cannot act stored variables.

i have following 2 loops in c++ code: for (int hcount = 0; hcount < height; hcount++) { (count = 0; count < width; count++) { cout << character; } cout << endl; } cout << endl; (int hcount = 0; hcount < height; hcount++); { (count = 0; count < width; count++) { cout << character; } cout << endl; } the problem running after using variable hcount in first loop, variable hcount in second loop initialize value had in first loop. not sure why both being initialized seem local variables , set equal 0. the problem here: for (int hcount = 0; hcount < height; hcount++); you end loop ; , no-op. hcount in case visible in scope of loop. after loop execution (i.e. after ; ), inner loop starts executing. debugger displays last value taken hcount .

i have nsbutton btnone , when user clicks on button, want simulate click on button btntwo. btntwo has action displays message when clicked. - (ibaction)btnoneclicked:(id)sender { [btntwo performclick:self]; } - (ibaction)btntwoclicked:(id)sender { nslog(@"btntwo clicked"); } when run program , click on btnone, performclick not seem simulate click on btntwo no message displayed. i've tried overriding performclick() of btntwo in nsbutton subclass display message. -(void)performclick:(id)sender { nslog(@"performclick"); } this not happening. message not getting displayed. what doing wrong? thanks. i know it's late answer, better late never, right? :) add [super performclick:sender] at end of overridden performclick method. why doesn't call action method in first place (without overriding performclick) thing can have many problems. buttons connected action methods?

i trying app can switch between google's default en-uk male voice (en-gb-x-rjs-phone-hmm) , female voice (en-gb-x-fis-phone-hmm). using 2 text-to-speech objects and, after initializing engine each one, assign corresponding voice each of them setvoice(voice). mtts1 = new texttospeech(this, oninitlistener, packname); mtts2 = new texttospeech(this, oninitlistener, packname); and in oninit() method, when both initialized: mtts1.setvoice(voice1); mtts2.setvoice(voice2); 'voice1' , 'voice2' obtained calling getvoices(), , when voice name, obtain 'en-gb-x-rjs-phone-hmm' , 'en-gb-x-fis-phone-hmm' respectively, make me think voices correctly stored. when display 2 buttons making them speak, female voice speaks in both cases. think it's fact of default voice. happens having female voice default voice. when set male voice default one, happens opposite. something should know i'm missing...? thank all,

i create dmg file java. the reason why needs java twofold: must part of our build farm (which runs on non mac os x platform) , our build uses maven (which pretty means java). as far can tell inside dmg file can iso9660 file system. can create such beast using this still need part whole thing wrapped in dmg format. iso2dmg tool except need java. when answering: forget maven part. if have java solution can figure out maven stuff myself. (e.g. creating own little maven plugin if need to). you can use javapackager tool. a simple, explained, step step tutorial on how create dmg java here: http://centerkey.com/mac/java/

in angularjs, inline javascript code included in html templates doesn't work. for example: main.html file: <div ng-include="'/templates/script.html'"></div> and script.html file: <script type="text/javascript"> alert('yes'); </script> when open main page, expect alert message 'yes' nothing happens. think security restrictions in angularjs preventing inline scripts, couldn't find workaround that. note: don't use jquery or other framework, angularjs 1.2.7. jqlite not support script tags. jquery does, recommendation include jquery if need functionality. from angular's igor minar in this discussion : we looked supporting script tags in jqlite, needs done cross-browser support involves lot of black magic. reason decided going recommend users use jquery along angular in particular case. doesn't make sense rewrite 1 third of jquery working in jqlite. here...

i attempting utilize side-menu github repo. animation menu requires class viewanimator take parameter actionbaractivity , given in sample this (i.e. mainactivity , extends actionbaractivity ). due actionbaractivity being deprecated, , mainactivity extending appcompatactivity , statement shows error. is there way around this? 1) use actionbaractivity. 2) download source code of github repo, import project (not gradle, or .jar, mean actual source code), , modify function accept appcompatactivity instead of actionbaractivity. (this require testing see if still worked expected). 3) make issue on github repo , hope original developer can/will out modifying code. you can't trick thinking it's getting actionbaractivity if isn't it's getting.

i have noticed, scala doesn't execute instructions in order. example, if have following instructions. var = command1.! var b = command2.! the second instruction may executed before first 1 because doesn't have dependency on instruction. so, question is, how can force second instruction executed after first instruction. answering question, how compose processbuilder?, doc says: two existing processbuilder can combined in following ways: they can executed in parallel, output of first being fed input second, unix pipes. achieved #| method. they can executed in sequence, second starting first ends. done ### method. the execution of second 1 can conditioned return code (exit status) of first, either when it's zero, or when it's not zero. methods #&& , #|| accomplish these tasks.
