java - Does jOOQ support linked SQL Servers? -

this seems straight-forward question, can't track down answer without testing it: does jooq support linked sql servers? (sql server 2008 r2). have application running in sql server r2 aws-rds instance , it's running out of space, we're looking @ various options. 1 we're favoring right moving specific set of data onto it's own rds instance (for architectural reasons). we're trying determine impact of doing our application tier. does know if jooq code generator creates objects linked servers? officially, has never been tested explicitly. might work, depending on how sql server exposes linked instances. jooq's code generator runs queries against sql server's information_schema views. i.e. can generate artefacts find in views. note, if jooq cannot generate artefacts linked instance, connect instance directly jooq code generator, , try use codegen-time or runtime schema mapping features , in order generate link prefixes.

c# - Using DateTime for a duration of time e.g. 45:00 -

i'd know if possible use datetime type durations such 45:00 (45 minutes) or 120:00 (120 minutes). these values need stored local sql server db. if possible, possibly hint how done using datetime, or if not let me know way done using different type. thank in advance, jamie you should use timespan structure timespan interval = new timespan(0, 45, 0); console.writeline(interval.tostring()); for database storing part, store property ticks because specific constructor timespan structure allows instantiate new timespan passing ticks value long ticks = gettimespanvaluefromdb(); timespan interval = new timespan(ticks); i wish add need bigint t-sql datatype field store long net datatype

java - How large does a graph need to be to trigger the worst-case complexity of a Fibonacci heap? -

i've been trying trigger worst-case complexity of fibonacci heap using dijkstra's algorithm apparently no luck. have second implementation of dijkstra's using vanilla binary heap, , seems win. told conduct tests using larger datasets, have, shown (copy-pasted straight program): running dijkstra's algorithm 3354 nodes , 8870 links... source node: time using binary heap = 2167698339 ns (2167.70 ms) versus... running dijkstra's algorithm 3354 nodes , 8870 links... source node: time using fibonacci heap = 11863138070 ns (11863.14 ms) 2 seconds, against ~12 seconds. quite difference alright. now, have graph whopping 264,000 nodes , 733,000 edges. haven't had chance test yet, enough theoretical advantage of fibonacci heaps shine? i hope don't need on million nodes. mean it's not biggest issue in world nice see difference in action once. first of question's title not correct. size of input not affect worst case complexity. need size...

naming - Case of names of built-in JavaScript types -

in javascript, typeof 0 gives 'number' not 'number' , instanceof 0 number . would accurate canonical names of built-in types capitalized, , lowercase return value of typeof quirk/inconsistency can't changed historical reasons, changed if be? or missing something? no, actually number built-in value type number object. if typeof there's no need temporarily convert 0 object. if use instanceof, temporarily converts 0 object. this similar string: "sometest" => string however, if "sometest".tolowercase() first (temporarily) convert string string-object , call method on object (since value-types can't have methods). in short, lowercase means value-type, uppercase means object

Javascript - how to delete an object? -

i have object: var myobj = new myawsumobj(); now, deleting that: myobj = undefined; but apparently nothing, since object still exists (i can see exceptions being thrown in 'external' javascript file object defined in). how clear stuff up? possible? because seems myobj doing in external javascript file, maybe creating new objects, possible clear mess without refactoring external file? unfortunately, it's not possible. description, object seems creating references itself, adding event handlers, setting timeouts/intervals, ajax callbacks, whatever. if clear references object created yourself, you'd still have clear references creates on own. become inactive, unreferenced, , eligible garbage collection. but source code, maybe object provides "destruct" method take care of mess.
