sql server - SQL: Filter records based on record creation date and other criteria -


i struggling find better solution pick unique records user call data table. table structure follows: 

select [marketname],        [websitename] ,        [id] ,        [userid],        [creationdate],        [callduration],        [fromphone] ,        [tophone],        [isanswered],        [source] [dbo].[usercalldata]

there multiple entries in table different , same id's. wanted check if [fromphone] , [tophone] exists multiple times within last 3 months, if yes, wanted pick first record columns based on [creationdate], count number of occurrences totalcallcount , sum totalcallduration single record. if [fromphone] , [tophone] not occur multiple times, wanted pick columns such. have been able put partial query below. doesn't return columns without including in group clause , doesn't satisfy entire criteria. on highly appreciated.

select  [fromphone],          min([creationdate]),         [tophone],          marketname,          count(*) totalcallcount ,          sum(callduration) totalcallduration  [dbo].[usercalldata]  [creationdate] >= dateadd(month, -3, getdate()) group  [fromphone],[tophone], marketname  having count([fromphone]) > 1 , count([tophone]) >1

try use row_number()

;with cte (     select *, row_number() over(partition fromphone, tophone order creationdate) rn     usercalldata     creationdate >= dateadd(month, -3, getdate()) ), cte_totals (     select c1.fromphone, c1.tophone, count(*) totalcallcount, sum(callduration) totalcallduration     cte c1     exists(select * cte c2 c1.fromphone = c2.fromphone , c1.tophone = c2.tophone , c2.rn > 1)     group c1.fromphone, c1.tophone ) select c1.*, totalcallcount, totalcallduration cte c1     inner join cte_totals c2 on c1.fromphone = c2.fromphone , c1.tophone = c2.tophone c1.rn = 1

i wrote query right in here can have mistakes or mistypes, main idea might clear.

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
