i working on view in sql server 2012 long (has around 800 columns). allow users add custom columns table(a separate ui allows user specify column name, type , max length).once column added table, must reflected in view too. there way automatically accomplish ? right now, need create alter view statement existing 800+ columns , newly added column. also, can sp_refreshview used purpose? looking answers. in advance. if manually set columns included view (i mean select column1, column2 from ), automatic update isn't possible. if select * used in view (bad practice), there solution : exec sp_refreshview [dbo.v_customer] and more common form here (update views).

i have code have nested <script> tag, inner script tag nothing loads javascript file using src attribute. because, how in code, inner script tag closing outer script. since inside javascript mode, there way load script without using <script src=""> call? var js = document.createelement("script"); js.type = "text/javascript"; js.src = "path_to_the_file.js"; document.body.appendchild(js); but asynchronous, have wait until script loaded use - var js = document.createelement("script"); js.type = "text/javascript"; js.src = "path_to_the_file.js"; js.onload = function() { //code using script here }; document.body.appendchild(js);

i have spring boot application, shows data mongodb on angularjs page , allows user change it. now need create mechanism, allows me to run long (1-3 hours) java method, which produces files and observe state via web (does run, finished, did crash?). can implement in scope of spring boot application? if yes, parts of spring can use that? i argue it's not idea embed batch processing service exposing mongodb data store. i create separate batch application . spring batch natural choice if using spring stack. need figure out how want host spring batch job , how want trigger , schedule it. spring batch needs sql storage it's metadata . status of batch processing monitored 1 other application spring batch admin module running on servlet container . if point application sql storage of spring batch job application, monitoring of status via web ui out of box . of course run each app spring boot. if don't want handle operational complexity brings host...

i using tsclust package sax (symbolic aggregate aggregation) plots. in accordance example shown on page 25 , using function sax.plot(as.ts(df$power), w=30, alpha=4) but, generates error as: error in if ((n <- as.integer(n[1l])) > 0) { : argument of length 0 i not able debug it. looked source code of sax.plot function not find relevant error message typed in. the required r dataobject can found @ link r version: 3.2 tsclust version:1.2.3 hello apparently it's because need normalize data, check out example : # parameters w <- 30 alpha <- 4 # paa x <- df$power paax <- paa(x, w) plot(x, type="l", main="paa reduction of series x") p <- rep(paax,each=length(x)/length(paax)) #just plotting paa lines(p, col="red") # sax convert.to.sax.symbol(paax , alpha) # [1] 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 # need scale paa result convert.to.sax.symbol(scale(paax) , alpha) # [1] 1 1 1 1 1 1 ...

my problem nature key , auto_increment integer primary key. for example, have tables a , b , a_b_relation . , b may object, , a_b_realtion record many many relation of , b. both , b have own global unique id, such uuid. uuid available user, means user may query or b uuid. there 2 ways design table's primary key. use auto_increment integer. a_b_relation reference integer fk. use uuid. a_b_relation reference uuid fk. for example, user want query b's info associate a's uuid. for first case, query flow this: first, query a's integer primary key uuid `a`. , then, query b's integer primary key `a_b_relation`. @ last, query b's info `b`. for latter case, flow below: query b's uuid `a_b_relation` a's uuid. query b's info `b`. so think, latter case more convenient. right? what's shortage of latter case? according opinion convenience of using either natural key of auto-increment key depends on program solution pr...
