  • Will TSQL become useless because of new ORMs? [closed]

    - by Saeed Neamati
    By introducing LINQ to SQL, I found myself and my .NET developer colleagues gradually moving from TSQL to C# to create queries on the database. Entity Framework made that shift almost permanent. Now it's nearly 2 years that I use LINQ to SQL and LINQ to Entities and haven't used TSQL that much. Yesterday, a colleague encountered a problem (he had to create a SP) and we went to help him. But we all found that our TSQL knowledge was diminished for sure, and a simple SP that seemed trivial to us 2 or 3 years ago, was a challenge to be solved yesterday. Thus it came to my mind that while TSQL's life is attached to SQL Server, and logically as long as SQL Server lives and doesn't change it's SQL language, TSQL would also live, practically it might die, and soon very few people might know it. Am I right? Do existence of ORMs like Entity Framework threaten TSQL's life and usability?

  • Script to establish SSH tunnel and then run another program that uses the tunnel

    - by Rob Hills
    I am running a GUI app (Gnucash) that connects to a remote Postgres database via a secure shell session. I can use the SSH -L command to tunnel a local port and then separately run Gnucash and this works fine. What I'd like to do is use a single shell script that sets up the tunnel and then calls Gnucash. Is that possible? If so, how do I do it? Currently, I run commands like the following in 2 separate terminal windows: ssh -L 5433:127.0.0.1:19097 [email protected] gnucash postgres://gnucash@localhost:5433/gnucash_db If I simply put both lines in a shell script, the first line drops me into the remote shell and the second line doesn't execute until I exit the remote shell. TIA, Rob Hills

  • ASP.NET MVC: Converting business objects to select list items

    - by DigiMortal
    Some of our business classes are used to fill dropdown boxes or select lists. And often you have some base class for all your business classes. In this posting I will show you how to use base business class to write extension method that converts collection of business objects to ASP.NET MVC select list items without writing a lot of code. BusinessBase, BaseEntity and other base classes I prefer to have some base class for all my business classes so I can easily use them regardless of their type in contexts I need. NB! Some guys say that it is good idea to have base class for all your business classes and they also suggest you to have mappings done same way in database. Other guys say that it is good to have base class but you don’t have to have one master table in database that contains identities of all your business objects. It is up to you how and what you prefer to do but whatever you do – think and analyze first, please. :) To keep things maximally simple I will use very primitive base class in this example. This class has only Id property and that’s it. public class BaseEntity {     public virtual long Id { get; set; } } Now we have Id in base class and we have one more question to solve – how to better visualize our business objects? To users ID is not enough, they want something more informative. We can define some abstract property that all classes must implement. But there is also another option we can use – overriding ToString() method in our business classes. public class Product : BaseEntity {     public virtual string SKU { get; set; }     public virtual string Name { get; set; }       public override string ToString()     {         if (string.IsNullOrEmpty(Name))             return base.ToString();           return Name;     } } Although you can add more functionality and properties to your base class we are at point where we have what we needed: identity and human readable presentation of business objects. Writing list items converter Now we can write method that creates list items for us. public static class BaseEntityExtensions {            public static IEnumerable<SelectListItem> ToSelectListItems<T>         (this IList<T> baseEntities) where T : BaseEntity     {         return ToSelectListItems((IEnumerator<BaseEntity>)                    baseEntities.GetEnumerator());     }       public static IEnumerable<SelectListItem> ToSelectListItems         (this IEnumerator<BaseEntity> baseEntities)     {         var items = new HashSet<SelectListItem>();           while (baseEntities.MoveNext())         {             var item = new SelectListItem();             var entity = baseEntities.Current;               item.Value = entity.Id.ToString();             item.Text = entity.ToString();               items.Add(item);         }           return items;     } } You can see here to overloads of same method. One works with List<T> and the other with IEnumerator<BaseEntity>. Although mostly my repositories return IList<T> when querying data there are always situations where I can use more abstract types and interfaces. Using extension methods in code In your code you can use ToSelectListItems() extension methods like shown on following code fragment. ... var model = new MyFormModel(); model.Statuses = _myRepository.ListStatuses().ToSelectListItems(); ... You can call this method on all your business classes that extend your base entity. Wanna have some fun with this code? Write overload for extension method that accepts selected item ID.

  • An abundance of LINQ queries and expressions using both the query and method syntax.

    - by nikolaosk
    In this post I will be writing LINQ queries against an array of strings, an array of integers.Moreover I will be using LINQ to query an SQL Server database. I can use LINQ against arrays since the array of strings/integers implement the IENumerable interface. I thought it would be a good idea to use both the method syntax and the query syntax. There are other places on the net where you can find examples of LINQ queries but I decided to create a big post using as many LINQ examples as possible. We...(read more)

  • MySQL Query Cache

    - by BRADINO
    According to MySQL.com the query cache stores the text of a SELECT statement together with the corresponding result that was sent to the client. If an identical statement is received later, the server retrieves the results from the query cache rather than parsing and executing the statement again. The query cache is shared among sessions, so a result set generated by one client can be sent in response to the same query issued by another client. Purely hypothetical example: SELECT `name` FROM `beers` WHERE `favorite` = true To force the database NOT to give you a cached result simply add SQL_NO_CACHE to the query: SELECT SQL_NO_CACHE `name` FROM `beers` WHERE `favorite` = true mysql query cache sql no cache mysql nocache

  • Minidlna Directory Issues

    - by Somnambulist
    I've done my searching and can't find an answer to THIS specific issue. I have my minidlna set up and running - but it's not really done properly. First off, when I open the server on my bluray player, all of my movies are listed twice - when they are certainly not saved on my external twice. Second, when I open the server - rather than reading "Movies" "TV" "Music", etc - It just mashes all of my movies, tv, and some other folders all together with no real organization. I never had this problem when I had my Windows set up, so I know it's something configured improperly more-so than my external drive giving me gruff. Here's my minidlna.conf file: # This is the configuration file for the MiniDLNA daemon, a DLNA/UPnP-AV media # server. # # Unless otherwise noted, the commented out options show their default value. # # On Debian, you can also refer to the minidlna.conf(5) man page for # documentation about this file. media_dir=/media/somnambulist/Ghost In You # This option can be specified more than once if you want multiple directories # scanned. # # If you want to restrict a media_dir to a specific content type, you can # prepend the directory name with a letter representing the type (A, P or V), # followed by a comma, as so: # * "A" for audio (eg. media_dir=A,/var/lib/minidlna/music) # * "P" for pictures (eg. media_dir=P,/var/lib/minidlna/pictures) # * "V" for video (eg. media_dir=V,/var/lib/minidlna/videos) # # WARNING: After changing this option, you need to rebuild the database.

  • Where do we put "asking the world" code when we separate computation from side effects?

    - by Alexey
    According to Command-Query Separation principle, as well as Thinking in Data and DDD with Clojure presentations one should separate side effects (modifying the world) from computations and decisions, so that it would be easier to understand and test both parts. This leaves an unanswered question: where relatively to the boundary should we put "asking the world"? On the one hand, requesting data from external systems (like database, extental services' APIs etc) is not referentially transparent and thus should not sit together with pure computational and decision making code. On the other hand, it's problematic, or maybe impossible to tease them apart from computational part and pass it as an argument as because we may not know in advance which data we may need to request.

  • Configuring thouands of related products in Magento?

    - by Anonymous -
    I'm at a stage with a Magento store I'm developing where I've added all the products (all 6000 of them) and now would like to configure related products to up my conversion rate a bit. I was wondering if there was an extension anybody knew of that functions similarly to this one, with the most current version of Magento (Community Edition, 1.6.1). If not, would anyone be able to provide some pointers for writing a script that will run through each product and add 1-5 related products. I have a fairly basic idea of taking product title text and just doing a simple text similarity query between other product titles for now, just to get some related products up there, but the Magento database isn't making a terribly large amount of sense. Thanks to anyone who can shed some light on this. :)

  • A Rose by Any Other Name..

    - by Geoff N. Hiten
    It is always a good start when you can steal a title line from one of the best writers in the English language.  Let’s hope I can make the rest of this post live up to the opening.  One recurring problem with SQL server is moving databases to new servers.  Client applications use a variety of ways to resolve SQL Server names, some of which are not changed easily <cough SharePoint /cough>.  If you happen to be using default instances on both the source and target SQL Server, then the solution is pretty simple.  You create (or bug the network admin until she creates) two DNS “A” records. One points the old name to the new IP address.  The other creates a new alias for the old server, since the original system name is now redirected.  Note this will redirect ALL traffic from the old server to the new server, including RDP and file share connection attempts.    Figure 1 – Microsoft DNS MMC Snap-In   Figure 2 – DNS New Host Dialog Box Both records are necessary so you can still access the old server via an alternate name. Server Role IP Address Name Alias Source 10.97.230.60 SQL01 SQL01_Old Target 10.97.230.80 SQL02 SQL01 Table 1 – Alias List If you or somebody set up connections via IP address, you deserve to have to go to each app and fix it by hand.  That is the only way to fix that particular foul-up. If have to deal with Named Instances either as a source or a target, then it gets more complicated.  The standard fix is to use the SQL Server Configuration Manager (or one of its earlier incarnations) to create a SQL client alias to redirect the connection.  This can be a pain installing and configuring the app on multiple client servers.  The good news is that SQL Server Configuration Manager AND all of its earlier versions simply write a few registry keys.  Extracting the keys into a .reg file makes centralized automated deployment a snap. If the client is a 32-bit system, you have to extract the native key.  If it is a 64-bit, you have to extract the native key and the WoW (32 bit on 64 bit host) key. First, pick a development system to create the actual registry key.  If you do this repeatedly, you can simply edit an existing registry file.  Create the entry using the SQL Configuration Manager.  You must use a 64-bit system to create the WoW key.  The following example redirects from a named instance “SQL01\SQLUtiluty” to a default instance on “SQL02”.   Figure 3 – SQL Server Configuration Manager - Native Figure 3 shows the native key listing. Figure 4 – SQL Server Configuration Manager – WoW If you think you don’t need the WoW key because your app is 64 it, think again.  SQL Server Management Server is a 32-bit app, as are most SQL test utilities.  Always create both keys for 64-bit target systems. Now that the keys exist, we can extract them into a .reg file. Fire up REGEDIT and browse to the following location:  HKLM\Software\Microsoft\MSSQLServer\Client\ConnectTo.  You can also search the registry for the string value of one of the server names (old or new). Right click on the “ConnectTo” label and choose “Export”.  Save with an appropriate name and location.  The resulting file should look something like this: Figure 5 – SQL01_Alias.reg Repeat the process with the location: HKLM\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo Note that if you have multiple alias entries, ALL of the entries will be exported.  In that case, you can edit the file and remove the extra aliases. You can edit the files together into a single file.  Just leave a blank line between new keys like this: Figure 6 – SQL01_Alias_All.reg Of course if you have an automatic way to deploy, it makes sense to have an automatic way to Un-deploy.  To delete a registry key, simply edit the .reg file and replace the target with a “-“ sign like so. Figure 7 – SQL01_Alias_UNDO.reg Now we have the ability to move any database to any server without having to install or change any applications on any client server.  The whole process should be transparent to the applications, which makes planning and coordinating database moves a far simpler task.

  • Application Lifecycle Management with Visual Studio 2010 – Wrox Book

    - by Guy Harwood
    After running with a somewhat disconnected set of tools (vs 2008, Ontime, sharepoint 2007) for managing our projects we decided to make the move to Team Foundation Server 2010.  With limited coverage of the product available online i went in search of a book and found this… View this book on the Wrox website I must point out that i have only read 10 of the 26 chapters so far, mainly the ones that cover source code control, work item tracking and database projects.  This enables our dev team to get familiar with it before switching project management over at a future date. Needless to say i am very impressed with the detail it provides, answering pretty much every question i had about TFS so far.  I'm looking forward to digging into the sections on testing, code analysis and architecture. Highly recommended.

  • Microsoft Townhall, An Example for Azure and MVC

    - by Shaun
    Microsoft just released an example named Microsoft Townhall which was built and deployed on Azure. It uses ASP.NET MVC as its webiste framework and the SQL Azure plus LinqToSQL as its the database and the ORM framework. You can download the source code at the MSDN Code Gallery. Basides the Azure it might be more useful to us to learn how they utilized ASP.NET MVC. Just a very quickly review I found it utilized the Enterprise Library Unity as the main IoC container for controllers, services and repositories and customized a lot of ModelBinders, Filters, etc.   Hope this helps, Shaun   All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

  • Validating Data Using Data Annotation Attributes in ASP.NET MVC

    - by bipinjoshi
    The data entered by the end user in various form fields must be validated before it is saved in the database. Developers often use validation HTML helpers provided by ASP.NET MVC to perform the input validations. Additionally, you can also use data annotation attributes from the System.ComponentModel.DataAnnotations namespace to perform validations at the model level. Data annotation attributes are attached to the properties of the model class and enforce some validation criteria. They are capable of performing validation on the server side as well as on the client side. This article discusses the basics of using these attributes in an ASP.NET MVC application.http://www.bipinjoshi.net/articles/0a53f05f-b58c-47b1-a544-f032f5cfca58.aspx

  • Big Data – What is Big Data – 3 Vs of Big Data – Volume, Velocity and Variety – Day 2 of 21

    - by Pinal Dave
    Data is forever. Think about it – it is indeed true. Are you using any application as it is which was built 10 years ago? Are you using any piece of hardware which was built 10 years ago? The answer is most certainly No. However, if I ask you – are you using any data which were captured 50 years ago, the answer is most certainly Yes. For example, look at the history of our nation. I am from India and we have documented history which goes back as over 1000s of year. Well, just look at our birthday data – atleast we are using it till today. Data never gets old and it is going to stay there forever.  Application which interprets and analysis data got changed but the data remained in its purest format in most cases. As organizations have grown the data associated with them also grew exponentially and today there are lots of complexity to their data. Most of the big organizations have data in multiple applications and in different formats. The data is also spread out so much that it is hard to categorize with a single algorithm or logic. The mobile revolution which we are experimenting right now has completely changed how we capture the data and build intelligent systems.  Big organizations are indeed facing challenges to keep all the data on a platform which give them a  single consistent view of their data. This unique challenge to make sense of all the data coming in from different sources and deriving the useful actionable information out of is the revolution Big Data world is facing. Defining Big Data The 3Vs that define Big Data are Variety, Velocity and Volume. Volume We currently see the exponential growth in the data storage as the data is now more than text data. We can find data in the format of videos, musics and large images on our social media channels. It is very common to have Terabytes and Petabytes of the storage system for enterprises. As the database grows the applications and architecture built to support the data needs to be reevaluated quite often. Sometimes the same data is re-evaluated with multiple angles and even though the original data is the same the new found intelligence creates explosion of the data. The big volume indeed represents Big Data. Velocity The data growth and social media explosion have changed how we look at the data. There was a time when we used to believe that data of yesterday is recent. The matter of the fact newspapers is still following that logic. However, news channels and radios have changed how fast we receive the news. Today, people reply on social media to update them with the latest happening. On social media sometimes a few seconds old messages (a tweet, status updates etc.) is not something interests users. They often discard old messages and pay attention to recent updates. The data movement is now almost real time and the update window has reduced to fractions of the seconds. This high velocity data represent Big Data. Variety Data can be stored in multiple format. For example database, excel, csv, access or for the matter of the fact, it can be stored in a simple text file. Sometimes the data is not even in the traditional format as we assume, it may be in the form of video, SMS, pdf or something we might have not thought about it. It is the need of the organization to arrange it and make it meaningful. It will be easy to do so if we have data in the same format, however it is not the case most of the time. The real world have data in many different formats and that is the challenge we need to overcome with the Big Data. This variety of the data represent  represent Big Data. Big Data in Simple Words Big Data is not just about lots of data, it is actually a concept providing an opportunity to find new insight into your existing data as well guidelines to capture and analysis your future data. It makes any business more agile and robust so it can adapt and overcome business challenges. Tomorrow In tomorrow’s blog post we will try to answer discuss Evolution of Big Data.
