  • Optimizing ROW_NUMBER() in SQL Server

    - by BlueRaja
    We have a number of machines which record data into a database at sporadic intervals. For each record, I'd like to obtain the time period between this recording and the previous recording. I can do this using ROW_NUMBER as follows: WITH TempTable AS ( SELECT *, ROW_NUMBER() OVER (PARTITION BY Machine_ID ORDER BY Date_Time) AS Ordering FROM dbo.DataTable ) SELECT [Current].*, Previous.Date_Time AS PreviousDateTime FROM TempTable AS [Current] INNER JOIN TempTable AS Previous ON [Current].Machine_ID = Previous.Machine_ID AND Previous.Ordering = [Current].Ordering + 1 The problem is, it goes really slow (several minutes on a table with about 10k entries) - I tried creating separate indicies on Machine_ID and Date_Time, and a single joined-index, but nothing helps. Is there anyway to rewrite this query to go faster?

  • In which scenario it is useful to use Disassembly on python?

    - by systempuntoout
    The dis module can be effectively used to disassemble Python methods, functions and classes into low-level interpreter instructions. I know that dis information can be used for: 1. Find race condition in programs that use threads 2. Find possible optimizations From your experience, do you know any other scenarios where Disassembly Python feature could be useful?

  • Error trying to run rails server

    - by David87
    I am trying to get a basic Rails application to run on my Mac OS X 10.6.5. I created a new app called demo (rails new demo), then went into the demo directory and tried to start the app with rails server. Here is the error message I received: "/Users/dpetrovi/.gem/ruby/1.8/gems/sqlite3-ruby-1.3.2/lib/sqlite3/sqlite3_native.bundle: [BUG] Segmentation fault ruby 1.8.7 (2010-12-23 patchlevel 330) [i686-darwin10] Abort trap" I checked bundle install in the demo folder: "Using rake (0.8.7) Using abstract (1.0.0) Using activesupport (3.0.3) Using builder (2.1.2) Using i18n (0.5.0) Using activemodel (3.0.3) Using erubis (2.6.6) Using rack (1.2.1) Using rack-mount (0.6.13) Using rack-test (0.5.6) Using tzinfo (0.3.23) Using actionpack (3.0.3) Using mime-types (1.16) Using polyglot (0.3.1) Using treetop (1.4.9) Using mail (2.2.13) Using actionmailer (3.0.3) Using arel (2.0.6) Using activerecord (3.0.3) Using activeresource (3.0.3) Using bundler (1.0.7) Using thor (0.14.6) Using railties (3.0.3) Using rails (3.0.3) Using sqlite3-ruby (1.3.2) Your bundle is complete! Use bundle show [gemname] to see where a bundled gem is installed." Ruby, RubyGems, and sqlite3 were installed using MacPorts. Then I used gem to try to install the sqlite3-ruby interface. (sudo gem install sqlite3-ruby). Here is where I first noticed something could be off: "Successfully installed sqlite3-ruby-1.3.2 1 gem installed Installing ri documentation for sqlite3-ruby-1.3.2... No definition for libversion Enclosing class/module 'mSqlite3' for class Statement not known Installing RDoc documentation for sqlite3-ruby-1.3.2... No definition for libversion Enclosing class/module 'mSqlite3' for class Statement not known " I had rails running well on my system a few months ago, so I figured maybe I had some duplicates and it was trying to use the wrong one. I ran: "for cmd in ruby irb gem rake; do which $cmd; done" and got: "/opt/local/bin/ruby /opt/local/bin/irb /opt/local/bin/gem /opt/local/bin/rake" Checking where sqlite3 also gets me: "/opt/local/bin/sqlite3" so they all seem to be in the right place. Obviously /opt/local/bin is in my system path. If I check gems server, it shows that I have installed sqlite3-ruby 1.3.2 gem. Not sure what the problem could be? I am using ruby 1.8.7 (2010-12-23 patchlevel 330) [i686-darwin10]. Macports claims this is the latest (although ive seen 1.9.1) One more thing-- in irb, I tried to check which version of sqlite3 my sqlite3-ruby is bound to, but I can only get this far: ":irb(main):001:0 require 'rubygems' = true irb(main):002:0 require 'sqlite3' /Users/dpetrovi/.gem/ruby/1.8/gems/sqlite3-ruby-1.3.2/lib/sqlite3/sqlite3_native.bundle: [BUG] Segmentation fault ruby 1.8.7 (2010-12-23 patchlevel 330) [i686-darwin10] Abort trap" Any suggestions? Im hoping I overlooked something obvious. Thanks

  • Reading Binary Plist files with Python

    - by Zeki Turedi

I am wanting to read the data into a string to later to be analysed/printed etc. I am wondering if their is anyway of reading in a Binary Plist file without using the plutil function and converting the binary file into XML? Thank you for your help and time in advance.

  • NHibernate: insert multiple items at once

    - by Gart
    Hello, all! I am learning NHibernate now and I would like to know is it possible to save multiple objects to database in one operation. For example, consider this test code private static void SaveTestBillNamesInSession(ISession session, params string[] names) { var bills = from name in names select new Bill { Name = name, DateRegistered = DateTime.Now, }; foreach (var bill in bills) session.SaveOrUpdate(bill); } This loop here generates many INSERT statements which may be sub-optimal in SQL Server 2008 which allows to include multiple data rows in one INSERT statement. Is it possible to rewrite this code to make use of this functionality - insert all the data in one operation?

  • How to handle multiple delegates

    - by mac_55
    I've got a view in my app that does pretty much everything, and I like it that way. The problem however is that it's implementing 5 or 6 different delegates, which seems a little bit messy. My question is, does the view controller have to implement all of the delegates? or is there some way I can separate the code out into different files (without having to do a major restructure or rewrite)? Here's all the delegates I'm implementing: @interface MyView : UIViewController <UIScrollViewDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIActionSheetDelegate, MFMailComposeViewControllerDelegate>

  • Can I turn off an Apache Directive then turn it on in an include?

    - by javafueled
    I have a VirtualHost block that includes common configuration items, one directive is ProxyPreserveHost. Can I "procedurally" turn off ProxyPreserveHost for a Rewrite directive then have the include turn it back on? For example: <VirtualHost *:80> ServerName www.blah.com ... ... ProxyPreserveHost off RewriteRule /somepath http://otherhost/otherpath [P] Include /path/to/file/turning-on-ProxyPreserveHost </VirtualHost> The otherhost is on a CDN and preserving the host is creating some name resolution issue that is not allowing the proxying of content in the host namespace. ProxyReserveHost is only allowed in a Server Config or VirtualHost. It doesn't look like I can selectively turn it off for the ProxyPass and ProxyPassReverse directives (encapsulated in the proxy flag of mod_rewrite).

  • sql select statement with a group by

    - by user85116
    I have data in 2 tables, and I want to create a report. Table A: tableAID (primary key) name Table B: tableBID (primary key) grade tableAID (foreign key, references Table A) There is much more to both tables, but those are the relevant columns. The query I want to run, conceptually, is this: select TableA.name, avg(TableB.grade) where TableB.tableAID = TableA.tableAID The problem of course is that I'm using an aggregate function (avg), and I can rewrite it like this: select avg(grade), tableAID from TableB group by tableAID but then I only get the ID of TableA, whereas I really need that name column which appears in TableA, not just the ID. Is it possible to write a query to do this in one statement, or would I first need to execute the second query I listed, get the list of id's, then query each record in TableA for the name column... seems to me I'm missing something obvious here, but I'm (quite obviously) not an sql guru...

  • Best toolkit for new Web application (odd requirements)

    - by ireadit
    I need to write a new application, and have no experience with any new technology, framework, or language. Here are the requirements: HTML front end (best if it's cross-browser friendly) Web deployable, but also ideally want to be able to install as standalone on a desktop SQL Server database Ideally, would like to use a good (and easy) AJAX toolkit with widgets Ideally, would like to be able to write in ASP.Net but later (or concurrently) also write in Java. This is a big concern, as I would like to not have to rewrite the whole thing. Is there a toolkit I can use that makes this cross-platform requirement easier? All suggestions and comments are much appreciated. Thank you.

  • Is Zend Certification "needed" before starting with the Zend Framework?

    - by mojah
    Hi, We're starting a new project using the Zend Framework, because the ideas and expandability speaks to us. But now I'm wondering, should we first get some form of Zend Certification before starting with the Zend Framework? Will we miss fundamental yet basic groundrules if we just start "hacking away" using the Zend Framework? I don't want to see us have to redo (part of) the project, because we missed some vital guidelines from the beginning, forcing us to rewrite our code. If possible, I'd love to hear stories of others having used the Zend Framework, without certification, to see what limitations they ran accross.

    - by Devrim
    We want to rewrite kodingen.com backend with Go which currently is Java, running as daemon using jsvc. I have never touched any C in my life, am only experienced in Java so I don't know if this is something that I should even start. However, task is pretty simple read shell commands from mysql database queue and execute them in parallel save each shell output to the database that's it. So these simple requirements gives me hope that I can start using this wonderful language. What would you advise?
