sql server - SQL grouped statement with count and percentage -


i have table(simplified) 

id1  id2  status ---  ---  ------ 1    33     0  1    33     0  1    33     1  1    33     1  1    34     1  1    34     2  2    33     0 2    33     0 2    34     0

i want count total number of statuses grouped status type , percentage number of statuses pertaining particular ids id1 & id2

an example output be

id1  id2  status   count   percentage ---  ---  ------   -----   ---------- 1    33     0        2         50% 1    33     1        2         50% 1    34     1        1         50% 1    34     2        1         50% 2    33     0        2         100% 2    34     0        1         100%

so far have been able count, not percentage. query now

select id1, id2 ,  status, count(id2) count    stattable  group id1, id2, status

you can percentage using window functions total each id1, id2 combination:

select id1, id2 ,  status, count(*) cnt,        count(*) * 100.0 / count(*) on (partition id1, id2) percentage stattable group id1, id2, status;

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
