    - by Sagar Nikam
    I am dealing with a database (2.5 GB) having some tables only 40 row to some having 9 million rows data. when I am doing any query for large table it takes more time. I want results in less time small query on table which have 90 rows only-- hive> select count(*) from cidade; Time taken: 50.172 seconds hdfs-site.xml <configuration> <property> <name>dfs.replication</name> <value>3</value> <description>Default block replication. The actual number of replications can be specified when the file is created. The default is used if replication is not specified in create time. </description> </property> <property> <name>dfs.block.size</name> <value>131072</value> <description>Default block replication. The actual number of replications can be specified when the file is created.

  • Which browsers support html5 offline storage?

    - by Marcin
    Essentially, I wanted to run a piece of demo code from W3c Offline Webapps page. It looks like that: var db = window.openDatabase("notes", "", "The Example Notes App!", 1048576); Firefox 3.5, IE8 and Chrome do not seem to get it. Is there anybody out there that actually wrote support for that? Or is this wishful thinking about 'the standard of the future'?

  • Rails from with better url

    - by Sam
    wow, switching to rest is a different paradigm for sure and is mainly a headache right now. view <% form_tag (businesses_path, :method => "get") do %> <%= select_tag :business_category_id, options_for_select(@business_categories.collect {|bc| [bc.name, bc.id ]}.insert(0, ["All Containers", 0]), which_business_category(@business_category) ), { :onchange => "this.form.submit();"} %> <% end %> controller def index @business_categories = BusinessCategory.find(:all) if params[:business_category_id].to_i != 0 @business_category = BusinessCategory.find(params[:business_category_id]) @businesses = @business_category.businesses else @businesses = Business.all end respond_to do |format| format.html # index.html.erb format.xml { render :xml => @businesses } end end routes map.resources What I want to to is get a better url than what this form is presenting which is the following: http://localhost:3000/businesses?business_category_id=1 Without rest I would have do something like http://localhost:3000/business/view/bbq bbq as permalink or I would have done http://localhost:300/business_categories/view/bbq and get the business that are associated with the category but I don't really know the best way of doing this. So the two questions are what is the best logic of finding a business by its categories using the latter form and number two how to get that in a pretty url all through restful routes in rails.

  • SQL - Add up all row-values of one column in a singletable

    - by ThE_-_BliZZarD
    Hello Everybody, I've got a question regarding a SQL-select-query: The table contains several columns, one of which is an Integer-column called "size" - the task I'm trying to perform is query the table for the sum of all rows (their values), or to be more exact get a artifical column in my ResultSet called "overallSize" which contains the sum of all "size"-values in the table. Preferable it would be possible to use a WHERE-clause to add only certain values ("WHERE bla = 5" or something similar). The DB-engine is HSQLDB (HyperSQL), which is compliant to SQL2008. Thank you in advance :)

  • Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in file

    - by Jian Lin
    Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in files (pushing it)? It can be important that: 1) You never know it is in an inconsistent state, so you try for 2 hours trying to debug the code for what's wrong. 2) With all the framework code -- potentially hundreds of files -- if some files are inconsistent with the other, can't the rake db:migrate or script/generate controller cause some damage or inconsistencies to the code base?

  • "Ambiguous column name" error on one particular server

    - by jazbit
    This simple query throws the "Ambiguous column name TaskID" error on one db-server only. This is ridiculous. We tested this with the same database structure on different servers and different versions of ms sql (2005/2008), and it's only THIS particular client's server that throws the error. I'm actually frustrated. SELECT Tasks.TaskID FROM Tasks INNER JOIN TaskHelpers ON TaskHelpers.TaskID = Tasks.TaskID order by TaskID Yes, I know I can put "Tasks.TaskID" into the order by clause, but for some reasons I can't.

  • A Security (encryption) Dilemma

    - by TravisPUK
    I have an internal WPF client application that accesses a database. The application is a central resource for a Support team and as such includes Remote Access/Login information for clients. At the moment this database is not available via a web interface etc, but one day is likely to. The remote access information includes the username and passwords for the client's networks so that our client's software applications can be remotely supported by us. I need to store the usernames and passwords in the database and provide the support consultants access to them so that they can login to the client's system and then provide support. Hope this is making sense. So the dilemma is that I don't want to store the usernames and passwords in cleartext on the database to ensure that if the DB was ever compromised, I am not then providing access to our client's networks to whomever gets the database. I have looked at two-way encryption of the passwords, but as they say, two-way is not much different to cleartext as if you can decrypt it, so can an attacker... eventually. The problem here is that I have setup a method to use a salt and a passcode that are stored in the application, I have used a salt that is stored in the db, but all have their weaknesses, ie if the app was reflected it exposes the salts etc. How can I secure the usernames and passwords in my database, and yet still provide the ability for my support consultants to view the information in the application so they can use it to login? This is obviously different to storing user's passwords as these are one way because I don't need to know what they are. But I do need to know what the client's remote access passwords are as we need to enter them in at the time of remoting to them. Anybody have some theories on what would be the best approach here? update The function I am trying to build is for our CRM application that will store the remote access details for the client. The CRM system provides call/issue tracking functionality and during the course of investigating the issue, the support consultant will need to remote in. They will then view the client's remote access details and make the connection

  • selective UnknownHostException

    - by Stephan
    Hi everybody! I am getting said Exception in my program, but only in certain cases. First of all, I have the internet permission set:<uses-permission android:name="android.permission.INTERNET" />, and I tried the two method of this and this thread (they don't work in my case). The scenario is the following: I send a GET request to a rest service (e.g. http://my.web.site/request.php?attr=blah) and I do get a correct xml back. Now, in this xml there are some resources described, one of which is an url to an image (e.g http://my.web.site/images/img.jpg). Here it's where it fails! Here I consistently receive a UnknownHostException. I find it weird, since it's the same domain and everything. Accessing the img url from browser works (both from the emulator browser and pc browser). I tried from a device too but it doesn't get the image anyway. Any idea on why this weird behavior? EDIT: all my tests were on emulator and device, but connected to a wifi network. I tried also using the internet connection of my provider on the phone (i.e. bypassing home network), and still the behavior is the same... I found this bug which I assume is the source of this problem, but still no solution (after more than 1.5years). Any ideas?

  • Query interface for iPhone CoreData store

    - by JT
    Hi, another iPhone newbie question... I have the following: NSPersistentStoreCoordinator NSManagedObjectContext NSManagedObjectModel Is it possible to run queries directly on the store (since its a sqlite DB)? I'm trying to delete all the records from a tableview, and figured a "DELETE FROM table" would be nice and quick as opposed to looping through the records and removing them manually (which i'm also struggling with). Thanks for your time, James

  • Most efficient way to move a few SQL Server tables to SQLite?

    - by wom
    I have a fairly large SQL Server database; I'd like to pull 4 tables out and dump them directly into an sqlite.db for remote querying (via nightly batch). I was about to write a script to step through(most likely on a unix host kicked off via cron); but there should be a simpler method to export the tables directly (SQLite not an option in the included DTS Import/Export wizard) What would the most efficient method of dumping the SQL Server tables to SQLite via batch be?

  • <object> pasted into textarea is removed... why?

    - by swt83
    I have a textarea that saves data into a database. For some reason it is removing <object> tags from anything that I paste into it -- none of the other tags are removed, only <object> tags. I've never had this problem before and have done this same thing in times past -- any ideas as to what could cause this? I'm not filtering the data before it's saved to the db at all.

  • Confused about distinct/aggregate queries with (N)Hibernate

    - by nw
    I'm not sure how to approach queries that don't map 1:1 to my persistent entities - in other words, distinct and aggregate queries. For example, I need to retrieve a distinct list of property values for populating a drop-down list. Should I write a class and a mapping for the "entities" that are returned by this query? Or should I just use the native DB provider and work with native data sets instead?

  • PHP get values from SimpleXMLElement array
