sql - Return all rows from one table regardless of no data in other tables. Using Where Clause -


i have db handles reservations made against resources. i'm using ssrs 2008 r2. i've made sure joins in visual designer showing rows on resources table.

how can return rows resources table regardless of data in other joining tables? i'm using where clause parameters of start date , end date. these parameters refer dates on reservations table. if remove where clause resources. need start date , end date included can search between 2 dates. thought if did left outer join on resources table i'd resources. however, getting resources associated reservations made between start date , end date.

what doing wrong? 

select

(rows here)

from             _reservationsattributes  right outer join   _reservations on _reservationsattributes.reservationid = _reservations.reservationid    right outer join    _resources on _reservations.resourceid = _resources.resourceid  left outer join   _locationsattributes on _resources.locationid = _locationsattributes.locationid                             left outer join   _locations on _resources.locationid = _locations.locationid  left outer join   _resourcesattributes on _resources.resourceid = _resourcesattributes.resourceid   (_locationsattributes.[@33] = @distinct_premise) ,    (_reservations.startdate >= @start_date) ,    (_reservations.enddate <= dateadd(day, 1, @end_date)) order    _locations.orderby,    _resources.name

deconstruct query. start central table (_resources). add each of other tables in 1 @ time, where conditions. make sure each step makes sense before adding next table in.

my guess - getting confused using both left outer , right outer joins. need schema sure.

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...
