select tablea.z, count(tablea.z), count(tableb.y) tablea join tableb on tablea.y = tableb.y group tablea.z; i'm trying count(tableb.y)/count(tablea.z) . each 1 works fine when find them individually when join tables shown above, count(tablea.z) turns count(tableb.y) . any tips? you need able evaluate 2 table counts independently of each other: i may have trying count wrong, hope helps give idea on going on select a.z, a.numrows / b.numrows calc -- perhaps error checking avoid /0 error (select z, count(*) numrows tablea group z) join (select z, count(*) numrows tableb group z) b on a.z = b.z

im stuck have created folder current date (e.g test.20160419) , want select folder , copy records in folder through jbase command. can me in this. you need use copy (jbase knowledgebase) command trying achieve. for specific scenario, assuming want copy records src.table table test.20160419, command should be: copy src.table test.20160419 if need copy of records in src.table can select (jbase knowledgebase) before so select src.table @id = "a]" 3 records selected >copy src.table test.20160419 this copy selected files (in case starting a).

what's difference controller arguments, 1 wrapping services , return function in array, it seems type 1 obeys dry principle. i don't meaning of difference between following 2 syntax? type 1 app.controller("userctrl", ['$scope', '$http', '$resource', 'users', 'user', '$location', function($scope, $http, $resource, users, user, $location) { .... }]); type 2 app.controller("userctrl", function($scope, $http, $resource, users, user, $location) { .... }); difference how angular find dependencies. with type 1, angular uses string find dependencies, can have own parameter names. i.e. app.controller("userctrl", ['$scope', '$http', '$resource', 'users', 'user', '$location', function(s, h, r, us, u, l) { .... }]); with type 2, angular uses parameter names find dependencies, can't use whatever name like, otherwise, angul

how traffic manager monitors endpoints? it's obvious it's not event driven (when endpoint down takes up-to 30 secs - 2.5 mins identify status of endpoint per observations). can configure frequency, cannot see configuration this. is there relationship between traffic manager monitoring interval , ttl? this may general question, real issue experience service downtime in fail on scenario (fail on of primary). understand effect in ttl until client dns cache expires calling cached endpoint. spent lot of time on , have narrowed down specific question. issue there delay in traffic manager identifying endpoint status after it's stopped or started. need logical explanation this, not find azure reference explains this. traffic manager settings i need understand delay , plan down time. i have gone through same issue. check link, explains monitoring behaviour traffic manager monitoring the monitoring system performs get, not receive response in 10 seco

i'm creating android project have 2 versions, , i'm planning use library place common code both versions. i not find info related performance of resources: better place images, logos etc in common library, or place them in each of projects? to reduce duplication, you'd put them common library. there's better way if you're using gradle(which android studio supports), build variant . with method, can build multiple various versions of single app.

looking @ @javax.validation.constraints.min 's documentation: the annotated element must number value must higher or equal specified minimum. and looking @ @min.list see: defines several {@link min} annotations on same element. when useful define more 1 min annotation on same element? // example: defining more 1 @min on same element. @min.list(@min(1), @min(2), @min(3)) private int someint; what mean? unfortunately can't add comment...but think can read explain java bean validation: how specify multiple validation constraints of same type different groups?

by mpi_rsend man papers ,in order use mpi_rsend,we need guarantee receive posted. error if receive not posted before ready send called.but how guarantee receive posted ???.i try find examples mpi_rsend,but can not find anything.and how error ? in link mpi_rsend_error ,finally 1 said : " simply not use mpi_rsend - archaism, behaviour not well-defined, , made obsolete of protocol optimisations in modern mpi libraries ".so,which mpi libraries implement rsend ? in fact,using mpi_rsend give better performance mpi_send in algorithms. example code: void allgather_ring_rsend(void* data, int count, mpi_datatype datatype,mpi_comm communicator) { int me; mpi_comm_rank(communicator, &me); int world_size; mpi_comm_size(communicator, &world_size); int next=me+1; if(next>=world_size) next=0; int prev=me-1; if(prev<0) prev=world_size-1; int i,curi=me; for(i=0;i<world_size-1;i++) { mpi_rsend(data+curi*size

i'm starting react project es6 classes (and eslint airbnb config) , need webpack bundle them. i started react tutorial , tried using const react = require('react'); , const $ = require('jquery'); , realized bundle grew 15 kb 700 kb. decided include jquery , react , react-dom via <script/> tags. hash: 082980fb232d17977e55 version: webpack 1.13.0 time: 869ms asset size chunks chunk names bundle.js 13.3 kb 0 [emitted] app + 5 hidden modules but when remove const react = require('react'); , errors in code (e.g. : react must in scope when using jsx - react/react-in-jsx-scope). read docs webpack's externals , , tried doing : module.exports = { entry: { app: './main.js', }, output: { filename: 'bundle.js', }, externals: { jquery: 'jquery', $: '$', react: 'react', reactdom: 'reactdom', marked: 'marked', }, mod

i want check checkbox when value of "select" changed. no idea wrong code, maybe able see mistake: var selected; var div_id; $(".live_editor_test").focus(function() { selected = $(this).val(); div_id = $(this).closest("div").attr('id'); }); $(".live_editor_test").blur(function() { if (selected != $(this).val()) { $('#live-assigning_check_' + div_id).attr('checked', true); } }); live_editor_test class of select . div row element , parent of live_editor_test . live-assigning_check checkbox id. div_id increments there 1 row each mysql query. thanks in advance. .php : echo "<span class='content-row live-row-8' style=\"$colorcov\">"; echo "<select class=\"live_editor_test\" name=\"live_editor[$i]\" style=\"width:65px;font-size:10px;\">"; echo "<option value=\"\" selected></opt

i making first steps coding javascript. made courses , exploring webgl world using three.js i experimenting function used in examples of threes.org: function onwindowresize() { camera.aspect = window.innerwidth / window.innerheight; camera.updateprojectionmatrix(); renderer.setsize(window.innerwidth, window.innerheight); } with function can center geometry when reduce or increase width of browser's window , can make geometry smaller or bigger when reduce or increase height of browser's window. but thing when reduce height of window can see geometry because it's centered , smaller. when reduce width of window can't see geometry because it's centered not smaller. in example: http://codepen.io/gnazoa/pen/bjobzz tried avoid problem using object.scale.devidescalar(1.5); in onwindowresize() function, doesn't makes change. i searching solution because consider important correct experience, because mome
