postgresql - SQL Query - excluding rows where one value of a column with multiple values matches -


i have set of tables follows. (this simplified, several of these tables have other columns, i've tried pare down) 

website id     | _____________________________________  10001 10002 10003  domain names name                | website_id _____________________________________ surfinglikewoah.com | 10001 surfinglikewoah.net | 10001 ihatesurfing.com    | 10002 surfinghatesme.net  | 10003   promotion redemptions promo id            | website_id  _____________________________________ 0001                | 10001 0002                | 10001 0003                | 10001 0002                | 10002   promo codes promo id            | code  _____________________________________ 0001                | test 0002                | super-discount 0003                | double-discount

and i'm trying filter out accounts have promotion "test" - however, because these websites associated multiple promotion redemptions, wrong rows still appear in results. note: i'll filtering based on additional criteria, again columns may have multiple values per row, or may null.

here's query far: 

select distinct ws.id,  array(select distinct dn.name domainname dn ws.id = dn.website_id),  array(select p.code promotionredemption pr, promotion p p.id = pr.promotion_id        , pr.site_id = ws.id)   website ws  left join domainname dn on dn.website_id = ws.id left join promotionredemption pr on pr.site_id = ws.id left join promotion p on p.id = pr.promotion_id   p.code != 'test'  order     ws.id asc

this query should not returning surfinglikewoah.com result - does, because result has 2 other promotion redemptions not match 'test'. 

results:  10001 | {surfinglikewoah.com, surfinglikewoah.net} | {test, super-discount, double-discount}   10002 | {ihatesurfing.com} | {super-discount}  10003 | {surfinghatesme.net} | {}

i feel i'm missing obvious!

help appreciated.

what want find 1 record record not exist. last 2 words of last sentence key not exists. find lot of code uses outer joins think better served using exists clause.

the following query may not need, should close enough can adjust fix exact needs.

 select ws.id     array(select distinct dn.name domainname dn ws.id = dn.website_id),      array(select p.code promotionredemption pr, promotion p p.id = pr.promotion_id        , pr.site_id = ws.id)     website ws   not exists (         select      1                promotion p         left join   promotionredemption pr             on  p.id = pr.promotion_id                     pr.site_id = ws.id             , p.code = 'test'     )  order     ws.id asc

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
