  • SQL Server (2005) Linked Server Issue

    - by David.Chu.ca
    I have SQL Server 2005 with several linked server defined. One of them is a connection to an Oracle server and another one is an ODBC bridge to another server on a remote machine (ODBC server). Recently I tried to use the linked server to Oracle to update data with two large size tables by using several joints. The update query took too long time and finally there was exception thrown: Update O set value = l.value FROM OracleServer..schema.largesizeTable O Join localLargeSizeTable l on .... The problem is that after the exception, I realized that another linked server to ODBC was not working any more. I had to restart SQL server to get the ODBC linked server back. It looks that the linked server pool could be crashed if any of them failed(not like sandbox in Chrome for each tab and no impact on other tabs or Chrome application at all). I am not sure if my assumption is correct or not. Is this a known issue of SQL server 2005?

  • Why is cell phone software still so primitive?

    - by Tomislav Nakic-Alfirevic
    I don't do mobile development, but it strikes me as odd that features like this aren't available by default on most phones: full text search: searches all address book contents, messages, anything else being a plus better call management: e.g. a rotating audio call log, meaning you always have the last N calls recorded for your listening pleasure later (your little girl just said her first "da-da" while you were on a business trip, you had a telephone job interview, you received complex instructions to do something etc.) bluetooth remote control (like e.g. anyRemote, but available by default on a bluetooth phone) no multitasking capabilities worth mentioning and in general no e.g. weekly software updates, making the phone much more usable (even if it had to be done over USB, rather than over the network). I'm sure I was dumbfounded by the lack or design of other features as well, but they don't come to mind right now. To clarify, I'm not talking about smartphones here: my plain, 2-year old phone has a CPU an order of magnitude faster than my first PC, about as much storage space and it's ridiculous how bad (slow, unwieldy) the software is and it's not one phone or one manufacturer. What keeps the (to me) obvious software functionality vacuum on a capable hardware platform from being filled up? Edit: I believe a clarification on the multitasking point might be beneficial. I'll use my phone as an example, although the point is much more general. The phone can multitask and in fact does: you can listen to music and do something else at the same time. On the other hand, the way the software has been designed makes multitasking next to useless. (Ditto with the external touch screen: it can take touch commands, but only one application makes use of it, and only with 3 commands.) To take the multitasking example to the extreme, if I plug my phone into my laptop and it registers as an external disk, it doesn't allow any kind of operation: messages, calling, calendar, everything out of reach, although I can receive a call. No "battery life" issue there: it's charging while connected. BTW, another example of design below the current state of the art: I don't see a phone on the horizon which will remember where in an audio or video file you were when you stopped listening/watching it last time (podcasts are a good use case). Simplistic rewind/fast forward functionality only aggravates the problem.

  • Adding to the browser user agent string?

    - by stwissel
    I have a plug-in that handles its own url schema (something like mystuf:// ). If a user clicks on such a link when the plug-in isn't installed (s)he gets an ugly error. So I extended my installer to write into the Registry (for Internet Explorer) and the user.js (for Firefox) to ADD a custom string to the user agent string. These additions survive a browser upgrade nicely (Microsoft uses this technique to indicate the presence of the dotNet Framework). Now I need to extend this to Apple Safari and Google Chrome on all supported platforms. To be clear: I'm not looking how to REPLACE the user agent string, but how to amend it with additional information. Any hint?

  • How to organize asp.net mvc project (using entity framework) and a corresponding database project?

    - by Bernie
    I recently switched to vs2010 and am experimenting with asp.net MVC2. I am building a simple website and use the entity framework to design the data model. From the .edmx file, I generate the database tables. After a few iterations, I decided that it would be nice to have version control of the database schema as well, and therefore I added a database project into which I imported the script that is generated from the datamodel. As a result, I have to generate the sql every time that I change the model and redo the import. The database project automatically updates the database. Although the manual steps to generate the sql and the import are annoying, this works pretty well, until I wanted to add the standard tables for user accounts/authorization etc. I can use the framework tools to add the necessary tables, views etc. to the database, but as I do not want to have them in the .edmx model I end up with a third manual step. Is anybody facing similar issues?

  • Having a Backgroundworker refresh splash screen

    - by Jiri
    Hi, Would it be theoretically possible to make BackgroundWorker in a class to periodically refresh existing splash screen form, or is that impossible? (I know that it's probably bad design, but currently I do not see any better way.) Please keep in mind that: I do not want the background worker to do the loading as it would be terribly hard to implement. I can't use the inbuilt splash screen support I'm aware of DoEvents alternative but I do not want to go this path, it would very hard to implement as well, and not reliable.

    - by Abi Noda
    With browser support / licensing issues of @font-face (a feature of CSS3), which intermediate option do you prefer? Cufon,Typeface.js, or SIFR? Cufon is new but has been getting a lot of praise from the web design community, how does it differ from Typeface.js ?

  • How do views reduce code duplication?

    - by Debuger
    Hi! I read something like this about db views: Views are incredibly powerful and useful for one reason that stands out above all the other very good reasons. They reduce code duplication. That is, in most cases, the bottom line. If a query will be used in three or more places, then a view will drastically simplify your changes if the schema or query parameters change. I once had to edit 22 stored procedures to change some query logic. If the original architecture had utilized views, then I would have had only three changes. Can anyone explain to me how it works, and maybe give me some examples? Best regards!

  • Extract Rules from InfoPath Form

    - by marr75
    Is there a way to automatically grab the rules, in their original, human readable format from an InfoPath 2007 form (probably the manifest.xsf file, they're not human readable here)? A commercial tool would be fine, even. We're looking to build a summary of the rules as they appear in the design form for easy browsing by a maintenance team.

  • Relative paths in spring classpath resource

    - by Mike Q
    Hi all, I have a bunch of spring config files, all of which live under the META-INF directory in various subpackages. I have been using import like the following... <import resource="../database/schema.xml"/> So a relative path from the source file. This works fine when I am working with a local build outside of a jar file. But when I package everything up in a jar then I get an error that it cannot resolve the URL resource. If I change the above to an absolute path (with classpath:) then it works fine. Is there any way to use relative paths with ".." in when the configs are packaged in a jar or am I restricted to descending relative paths and absolute paths only? Thanks.

  • SQL count NULL cells

    - by Giuseppe
    Dear All, I have the following problem. I have a table in a db, with many columns. I can do different kind of select queries, to show, for example, for each record that satisfies a condition: all cells from columns with names ending in _t0 all cells from columns with names ending in _t1 ... To get the column lists to form the queries I use the information schema. Now, the problem: each query returns a record with a subset of the columns of the big table. This means that I can get a row of (all!) NULLs. How can I ask my query to reject such rows without having to type in explicitely the column names (i.e. by saying where col_1 is not null, col_2 is not null...)? Is it possible? Thanks in advance!!!

  • Rails Unit Testing with MyISAM Tables

    - by tadman
    I've got an application that requires the use of MyISAM on a few tables, but the rest are the traditional InnoDB type. The application itself is not concerned with transactions where it applies to these records, but performance is a concern. The Rails testing environment assumes the engine used is transactional, though, so when the test database is generated from the schema.rb it is imported with the same engine. Is it possible to over-ride this behaviour in a simple manner? I've resorted to an awful hack to ensure the tables are the correct type by appending this to test_helper.rb: (ActiveRecord::Base.connection.select_values("SHOW TABLES") - %w[ schema_info ]).each do |table_name| ActiveRecord::Base.connection.execute("ALTER TABLE `#{table_name}` ENGINE=InnoDB") end Is there a better way to make a MyISAM-backed model be testable?

  • Hibernate constraint ConstraintViolationException. Is there an easy way to ignore duplicate entries?

    - by vincent
    Basically I've got the below schema and I'm inserting records if they don't exists. However when it comes to inserting a duplicate it throws and error as I would expect. My question is whether there is an easy way to make Hibernate to just ignore inserts which would in effect insert duplicates? CREATE TABLE IF NOT EXISTS `method` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `name` varchar(10) DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `name` (`name`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ; SEVERE: Duplicate entry 'GET' for key 'name' Exception in thread "pool-11-thread-4" org.hibernate.exception.ConstraintViolationException: could not insert:

  • Performance tuning of a Hibernate+Spring+MySQL project operation that stores images uploaded by user

    - by Umar
    Hi I am working on a web project that is Spring+Hibernate+MySQL based. I am stuck at a point where I have to store images uploaded by a user into the database. Although I have written some code that works well for now, but I believe that things will mess up when the project would go live. Here's my domain class that carries the image bytes: @Entity public class Picture implements java.io.Serializable{ long id; byte[] data; ... // getters and setters } And here's my controller that saves the file on submit: public class PictureUploadFormController extends AbstractBaseFormController{ ... protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception{ MutlipartFile file; // getting MultipartFile from the command object ... // beginning hibernate transaction ... Picture p=new Picture(); p.setData(file.getBytes()); pictureDAO.makePersistent(p); // this method simply calls getSession().saveOrUpdate(p) // committing hiernate transaction ... } ... } Obviously a bad piece of code. Is there anyway I could use InputStream or Blob to save the data, instead of first loading all the bytes from the user into the memory and then pushing them into the database? I did some research on hibernate's support for Blob, and found this in Hibernate In Action book: java.sql.Blob and java.sql.Clob are the most efficient way to handle large objects in Java. Unfortunately, an instance of Blob or Clob is only useable until the JDBC transaction completes. So if your persistent class defines a property of java.sql.Clob or java.sql.Blob (not a good idea anyway), you’ll be restricted in how instances of the class may be used. In particular, you won’t be able to use instances of that class as detached objects. Furthermore, many JDBC drivers don’t feature working support for java.sql.Blob and java.sql.Clob. Therefore, it makes more sense to map large objects using the binary or text mapping type, assuming retrieval of the entire large object into memory isn’t a performance killer. Note you can find up-to-date design patterns and tips for large object usage on the Hibernate website, with tricks for particular platforms. Now apparently the Blob cannot be used, as it is not a good idea anyway, what else could be used to improve the performance? I couldn't find any up-to-date design pattern or any useful information on Hibernate website. So any help/recommendations from stackoverflowers will be much appreciated. Thanks

  • Is it ok to use <strong> in place of <b> blindly ?

    - by metal-gear-solid
    Note: I know <b> is presentational and <span style="font-weight:bold> is better way and <strong> and <em> for emphasis but my question is not regarding this. Should we convert every <b> to <strong> blindly ? many people do this they think <b> is not good as per web standards so they convert every <b> to <strong> upon site redesign, content re-population, new site design and people suggest this to others also. Dreamweaver has also given option to convert all <b> and <i> to <strong> and <em> on code paste in design view and when we use B and I Which people use blindly. And Dreamweaver(if above option is checked) and many online WYSIWYG editor give output in <strong> and <em> while button shows B and I. In my opinion it's creating misconception about <strong> and <b> When we get content from client we don't know where client want to give emphasize and where he just want to use text bold for presentation purpose.What we should do in this condition? no one has time client and we both to give time to think for each bold text, it should be in <b> or in <strong>, <i> or in <em> What are pros and cons to convert every <b> and <i> into <strong> and <em> blindly if we are saying our site is accessible? Update: remember <b> and <i> are not deprecated there are in HTML 5 specification
