when select empno input, should pass select query.

using below, running select * emp how can run select * emp empno = xxxx

in server.r want run select * emp empno = (user selected empno)

ui.r :

shinyui(bootstrappage(   title="reactive-bootstrap",responsive=true,theme=null,   titlepanel=h5("employee report - reactive"),    sidebarlayout(     sidebarpanel(       selectinput(inputid="select",label="select employee",                   choices=c(7369,7499,7521,7566),selected=7369)),      mainpanel(tableoutput("dis")))))

server.r :

library(rodbc) channel<-odbcconnect("shiny",uid="scott",pwd="tiger") shinyserver(function(input,output){   sql<-sqlquery(channel,"select * emp")   output$dis<-rendertable(print(sql)) })

lets dropdown menu id empno try this..

qry = paste0('select * emp empno ="',input$empno,'"') sql<-sqlquery(channel,qry) output$dis<-rendertable(print(sql))

p.s. assume input$empno linked ids in table. if not set when populate dropdown menu...

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
