  • Multiple foreign keys to same table using Elixir

    - by Suvir
    Hello, I am new to ORMs in general. I have a table (lets call it Entity) with columns -- ID expression type ( can be 'long_word', 'short_word' or 'sentence' ) Often, the first two types occur in a 'sentence', so, I want to maintain another table which maps 'Sentences' to 'long_word' or 'short_word' using the 'ID' field. All i need is another table with 2 'Integer fields' referring to 'ID' as a foreign key. But, how do i do this in Elixir? Thanks a lot...

  • csv file enclosed with double quotes not stripping quotes

    - by sjw
    I am generating a csv download from my web server and to be safe, I have enclosed each field with double quotes. i.e. "Field1","Field2","Field3","Field4" "row1_field1","row1_field2","row1_field3","row1_field4" "row2_field1","row2_field2","row2_field3","row2_field4" The problem is that when the file is opened in Excel, it does not strip all quotes... Therefore, some fields are appearing as: row1_field1 whereas others are appearing as "row1_field2" What am I not doing to ensure that excel strips all surrounding quotes?

  • MySQL Select names with last names ending with certain letter

    - by Brian
    I have a MySQL database with a field Name which contains full names. To select all people with last names ending in a particular letter, let's say A for this example, I use the following query: SELECT * FROM db WHERE Name LIKE '% A%'. However, this also selects users who have a middle name starting with A. Is there anyway to alter this query so that only a last name ending in A will be selected?

  • In JSF How can I understand of multi checkboxes whether all of them is checked or not?

    - by Bariscan
    As you understand from the title above, I have a datatable and checkboxes in each row. I want to enable a button when at least one checkbox is selected, and disable it when there is no selected checkboxes (I mean all of them is unselected). I could achieve this as like if one of the checkboxes is selected, the button becomes enable. However, the reversable case I have to do is when the checkboxes is being unselected, when the last selected checbox becomes unselected, the button immediately must become disabled... BTW, I must do it without using a setter method nor a backing bean. Can I perform it by using jquery or a jsfunction, richfaces, etc? As a result, I want to learn how I can disable a button at the moment when all of the checkboxes are unselected? In order to clarify the case, here is my code below; <h:selectBooleanCheckbox id="selectionCheck" onclick="document.getElementById('form1:button1').disabled=false" value="#{_apiV2Product.selectValue}" > </h:selectBooleanCheckbox> Any help would be appreciated, Many thanks, Baris

    - by Yossi
    I would like to have a custom ListView, where each row contains an EditText field, that may be edited by the user. But when I click on one of the EditTexts I loose the focus, and can't type text there (I suppose because the other raws are redrawed and get the focus). What can I do?

  • professor of Java not knowing Groovy or Scala, normal or abnormal

    - by user311884
    i went to a prestigeous software conference (as dominant in its own field as MS in general), one main speaker is a professor of computer science who has been teaching Java for 20 years. During question session, he seems never heard of Groovy or Scala.... He is from a decent University in US... Is Groovy or Scala too new to attract academic attention or is this professor abnormal? thanks.

  • What do you do to keep learning?

    - by tvanfosson
    When my children tell me that they hate school, I often tell them that they need to get used to continuous learning because they live in a generation in which constant learning will be required. How do I know -- because I live in a generation and work in an occupation in which continual learning is imperative. Do you agree with this sentiment? If so, what do you do to keep up with the continual pace of change in the field of software development?

  • SQL Server: Is it possible to prevent SQL Agent from failing a step on error?

    - by Kenneth
    I have a stored procedure that runs custom backups for around 60 SQL servers (mixes 2000 through 2008R2). Occasionally, due to issues outside of my control (backup device inaccessible, network error, etc.) an individual backup on one or two databases will fail. This causes this entire step to fail, which means any subsequent backup commands are not executed and half of the databases on a given server may not be backed up. On the 2005+ boxes I am using TRY/CATCH blocks to manage these problems and continue backing up the remaining databases. On a 2000 server however, for example, I have no way to prevent this error from failing the entire step: Msg 3201, Level 16, State 1, Line 1 Cannot open backup device 'db-diff(\PATH\DB-DIFF-03-16-2010.DIF)'. Operating system error 5(Access is denied.). Msg 3013, Level 16, State 1, Line 1 BACKUP DATABASE is terminating abnormally. I am simply asking if anything like TRY/CATCH is possible in SQL 2000? I realize there are no built in methods for this, so I guess I am looking for some creativity. Even when wrapping each backup (or any failing statement) via sp_executesql the job fails instantly. Example: DECLARE @x INT, @iReturn INT PRINT 'Executing statement that will fail with 208.' EXEC @iReturn = Sp_executesql N'SELECT * from TABLETHATDOESNTEXIST;' PRINT Cast(@iReturn AS NVARCHAR) --In SSMS this return code prints. Executed as a job it fails and aborts before this statement.

  • Export multiple values from a single Combo Box? (Adobe Acrobat)

    - by metashockwave
    I'm trying to export 2 values from every single item from the combo box field. I have found two methods to insert items into a combo box: 1) insertItemAt http://www.verypdf.com/document/acrobat-forms-javascript/pg_0048.htm 2) setItems http://livedocs.adobe.com/acrobat_sdk/9/Acrobat9_HTMLHelp/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Acrobat9_HTMLHelp&file=JS_API_AcroJS.88.748.html but neither method allows two parameters (im always get "missing ) after argument list" error from the Acrobat JavaScript Debugger) Does anyone know of a better solution for this problem? Thanks!

  • Parsing a blackberry .ipd file

    - by galaxywatcher
    I recently lost my Blackberry. When I discovered it was gone very shortly afterwards and called it, the sim card had already been removed. I ain't seeing that Blackberry again. Ok. I am out $300, but at least my data is backed up. I had an older working Blackberry fortunately and I got a new sim card and proceeded to restore my data using Blackberry Desktop Manager. 7000+ emails, hundreds of autotext entries, sms messages, calendar events, all backing up. Looking good. Lo and behold! My Address Book contacts refuse to back up? I try advanced, and it is greyed out as an option to restore. Far more frustrating than losing my bberry in the first place is wrangling with software that defies human logic. Ok, now I guess I will have to enter all 327 names by hand. That is, if I can read the .ipd file. I have tried the free version of ABC Amber Blackberry editor, but when I open the .ipd file, the contacts just do not show up. I am beginning to feel like the gods are conspiring against me. Then I found this: http://jabide.com/2009/03/parse-blackberry-ipd-files/ He posted a perl script that claims to extract the files. I copied and pasted the code and it did list all the different databases in my .ipd file, I was elated that a cool solution like this was published. I followed the instructions and garbled data with some discernible ascii was sent to standard output unlike a .csv file like he said it would. This is enough to make a grown man cry. Does anyone out there have a solution to extract my address book contacts from an .ipd file?

  • What is the fastest, most efficient way to get up to speed on a new technology?

    - by SLC
    My current job involves working with a huge number of technologies, most of which are very niche and unheard of. In some cases I have to write something about the technology, or with the technology, such as some lessons, examples, or tutorials, on behalf of the developer of that technology or someone that is backing it. When I get told to learn about a new technology, my first port of call is to check our internal library, and then look on amazon for a book on the subject. Failing that, or if the project is too small to warrant a purchase, I hit up google and youtube. However the results of randomly googling what I want to learn are hit and miss. Some days, I can find everything I want to know in a series of lessons or videos, and it's no problem. Other times, I can find almost nothing, and I really have to piece together things from sites. The result is that there are various resources out there, videos, interactive lessons, tutorials, books etc. but when I need to learn something fast, I often don't know the best way to go about it. It's not about fun, because I don't always have the luxury of working my way through a 600 page textbook named "A Complete Guide To Technology X", I have to deliver results quickly. One of the examples I'd like to use is ASP.NET MVC 2 which is something I have been told to learn. I grabbed a book on MVC 1 to refresh my knowledge, but googling it does't produce much useful information. I've seen a ton of ScottGu's tutorials on it, but they are mostly feature presentations, and some date back almost a year. The same applies to channel 9 and there are no books out yet on amazon. My question therefore has two parts, the first asks, "Where are the best places to look to get the information needed to learn a new technology?" and the second asks "What is the most efficient way to use such resources to learn a new technology?"

  • RowFilter including [ character in search string

    - by JeffC
    I fill a DataSet and allow the user to enter a search string. Instead of hitting the database again, I set the RowFilter to display the selected data. When the user enters a square bracket ( "[" ) I get an error "Error in Like Operator". I know there is a list of characters that need prefixed with "\" when they are used in a field name, but how do I prevent RowFilter from interpreting "[" as the beginning of a column name?

  • Inline instantiation of a constant List

    I try to do something like this: public const List<String> METRICS = new List<String>() { SourceFile.LOC, SourceFile.MCCABE, SourceFile.NOM, SourceFile.NOA, SourceFile.FANOUT, SourceFile.FANIN, SourceFile.NOPAR, SourceFile.NDC, SourceFile.CALLS }; But unfortunately this doesn't work: FileStorer.METRICS' is of type 'System.Collections.Generic.List<string>'. A const field of a reference type other than string can only be initialized with null. How can I solve this problem?
