sql - Concatenate multiple column into single in a resulted query -


i need in adding multiple column in single (db2) after resulted query

my resulted query looks like,

empi   hrs  mts  sds ------------------- sam    12   10   10 tukai  10   05   02

now, want output instead:

empid   totaltimetaken ---------------------- sam     12:10:10 tukai   10:05:02

first query:

select     empid     ,totalseconds/3600 hrs     ,(mod(totalseconds, 3600) /60) mts     ,(mod(totalseconds, 60)) sds      (select         sum(duration) totalseconds         ,empid      table      group empid)

from above query result, want add columns: empid, hrs, mts, sds.

i used query not getting result. help...

select      tmp1.emp     ,('0'||(totalseconds.tmp1)/3600)||':'||     ('0'||(mod(totalseconds.tmp1),3600)/60) ':'||     mod(totalseconds.tmp1),60) totaltimetaken     ,tmp1.totalseconds    (select         empid emp,        sum(duration) totalseconds     table     group empid) tmp1

this ibm db2.

you should using tmp1 prefix- 

select tmp1.emp, tmp1.totalseconds,            ('0' || (tmp1.totalseconds) / 3600) || ':' ||            ('0' || (mod(tmp1.totalseconds, 3600) / 60) ':' ||            mod(tmp1.totalseconds, 60) totaltimetaken (select empid emp, sum(duration) totalseconds       table       group empid) tmp1

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
