  • Join 2 children tables with a parent tables without duplicated

    - by user1847866
    Problem I have 3 tables: People, Phones and Emails. Each person has an UNIQUE ID, and each person can have multiple numbers or multiple emails. Simplified it looks like this: +---------+----------+ | ID | Name | +---------+----------+ | 5000003 | Amy | | 5000004 | George | | 5000005 | John | | 5000008 | Steven | | 8000009 | Ashley | +---------+----------+ +---------+-----------------+ | ID | Number | +---------+-----------------+ | 5000005 | 5551234 | | 5000005 | 5154324 | | 5000008 | 2487312 | | 8000009 | 7134584 | | 5000008 | 8451384 | +---------+-----------------+ +---------+------------------------------+ | ID | Email | +---------+------------------------------+ | 5000005 | [email protected] | | 5000005 | [email protected] | | 5000008 | [email protected] | | 5000008 | [email protected] | | 5000008 | [email protected] | | 8000009 | [email protected] | | 5000004 | [email protected] | +---------+------------------------------+ I am trying to joining them together without duplicates. It works great, when I try to join only Emails with People or only Phones with People. SELECT People.Name, People.ID, Phones.Number FROM People LEFT OUTER JOIN Phones ON People.ID=Phones.ID ORDER BY Name, ID, Number; +----------+---------+-----------------+ | Name | ID | Number | +----------+---------+-----------------+ | Steven | 5000008 | 8451384 | | Steven | 5000008 | 24887312 | | John | 5000005 | 5551234 | | John | 5000005 | 5154324 | | George | 5000004 | NULL | | Ashley | 8000009 | 7134584 | | Amy | 5000003 | NULL | +----------+---------+-----------------+ SELECT People.Name, People.ID, Emails.Email FROM People LEFT OUTER JOIN Emails ON People.ID=Emails.ID ORDER BY Name, ID, Email; +----------+---------+------------------------------+ | Name | ID | Email | +----------+---------+------------------------------+ | Steven | 5000008 | [email protected] | | Steven | 5000008 | [email protected] | | Steven | 5000008 | [email protected] | | John | 5000005 | [email protected] | | John | 5000005 | [email protected] | | George | 5000004 | [email protected] | | Ashley | 8000009 | [email protected] | | Amy | 5000003 | NULL | +----------+---------+------------------------------+ However, when I try to join Emails and Phones on People - I get this: SELECT People.Name, People.ID, Phones.Number, Emails.Email FROM People LEFT OUTER JOIN Phones ON People.ID = Phones.ID LEFT OUTER JOIN Emails ON People.ID = Emails.ID ORDER BY Name, ID, Number, Email; +----------+---------+-----------------+------------------------------+ | Name | ID | Number | Email | +----------+---------+-----------------+------------------------------+ | Steven | 5000008 | 8451384 | [email protected] | | Steven | 5000008 | 8451384 | [email protected] | | Steven | 5000008 | 8451384 | [email protected] | | Steven | 5000008 | 24887312 | [email protected] | | Steven | 5000008 | 24887312 | [email protected] | | Steven | 5000008 | 24887312 | [email protected] | | John | 5000005 | 5551234 | [email protected] | | John | 5000005 | 5551234 | [email protected] | | John | 5000005 | 5154324 | [email protected] | | John | 5000005 | 5154324 | [email protected] | | George | 5000004 | NULL | [email protected] | | Ashley | 8000009 | 7134584 | [email protected] | | Amy | 5000003 | NULL | NULL | +----------+---------+-----------------+------------------------------+ What happens is - if a Person has 2 numbers, all his emails are shown twice (They can not be sorted! which means they can not be removed by @last) What I want: Bottom line, playing with the @last, I want to end up with somethig like this, but @last won't work if I don't arrange ORDER columns in the righ way - and this seems like a big problem..Orderin the email column. Because seen from the example above: Steven has 2 phone number and 3 emails. The JOIN Emails with Numbers happens with each email - thus duplicated values that can not be sorted (SORT BY does not work on them). **THIS IS WHAT I WANT** +----------+---------+-----------------+------------------------------+ | Name | ID | Number | Email | +----------+---------+-----------------+------------------------------+ | Steven | 5000008 | 8451384 | [email protected] | | | | 24887312 | [email protected] | | | | | [email protected] | | John | 5000005 | 5551234 | [email protected] | | | | 5154324 | [email protected] | | George | 5000004 | NULL | [email protected] | | Ashley | 8000009 | 7134584 | [email protected] | | Amy | 5000003 | NULL | NULL | +----------+---------+-----------------+------------------------------+ Now I'm told that it's best to keep emails and number in separated tables because one can have many emails. So if it's such a common thing to do, what isn't there a simple solution? I'd be happy with a PHP Solution aswell. What I know how to do by now that satisfies it, but is not as pretty. If I do it with GROUP_CONTACT I geat a satisfactory result, but it doesn't look as pretty: I can't put a "Email type = work" next to it. SELECT People.Ime, GROUP_CONCAT(DISTINCT Phones.Number), GROUP_CONCAT(DISTINCT Emails.Email) FROM People LEFT OUTER JOIN Phones ON People.ID=Phones.ID LEFT OUTER JOIN Emails ON People.ID=Emails.ID GROUP BY Name; +----------+----------------------------------------------+---------------------------------------------------------------------+ | Name | GROUP_CONCAT(DISTINCT Phones.Number) | GROUP_CONCAT(DISTINCT Emails.Email) | +----------+----------------------------------------------+---------------------------------------------------------------------+ | Steven | 8451384,24887312 | [email protected],[email protected],[email protected] | | John | 5551234,5154324 | [email protected],[email protected] | | George | NULL | [email protected] | | Ashley | 7134584 | [email protected] | | Amy | NULL | NULL | +----------+----------------------------------------------+---------------------------------------------------------------------+

  • how do I match movement of an object from 2d video into a 3d package ?

    - by George Profenza
    I'm trying to add objects in a 3d package(Blender) using recorded footage. I've played with Icarus and it's great to capture the camera movement. Also the Blender 2.41 importer script works in Blender 2.49 as well. The problem is I can't seem to get 3d coordinates for objects. I have tried Autodesk(RealVIZ) MatchMover 2011 and gone through the tutorials. Tutorial 3 shows how to link a vertex from a 3d mesh to a 2d trackpoint, but the setup is for camera movement. Tutorial 4 goes into Motion capture, but it uses 2 videos of the same motion taken with 2 cameras from different viewpoints. I've tried to bypass that using the same footage twice, but that failed, as the 3d coordinate system ends up messed up. What software do you recommend for this (mapping 3d coordinates to 2d tracked points and importing them into a 3d package) ? What is the recommended technique ? Any good examples out there ?

  • jquery: validate that text field is numeric

    - by George Johnston
    I have simple issue -- I would like to check a field to see if it's numeric if it is not blank. I'm not using any additional plugins, just jQuery. My code is as follows: if($('#Field').val() != "") { if($('#Field').val().match('^(0|[1-9][0-9]*)$')) { errors+= "Field must be numeric.<br/>"; success = false; } } ...It doesn't seem to work. Where am I going wrong? Thanks, George

    In my app, I start an activity and then on button click, display an http url (using Intent - VIEW_ACTION) So when in the middle of the activity, if the user clicks the button called "Google", it opens up google.com in the browser. When I hit the back button, it comes back to my original activity screen. How can I get my activity to resume from where it left of? Thanks George

  • VBA regex pattern

    - by KeyMs92
    This is probably a simple problem, but unfortunately I wasn't able to get the results I wanted... Say, I have the following line: "Wouldn't It Be Nice" (B. Wilson/Asher/Love) I would have to look for this pattern: " (<any string>) In order to retrieve: B. Wilson/Asher/Love I tried something like "" (([^))]*)) but it doesn't seem to work. Also, I'd like to use Match.Submatches(0) so that might complicate things a bit because it relies on brackets...

  • Creating secure .exe files in C#

    - by George
    Hi, I have heard some mutterings about C# being quite easy to "crack" and/or reverse engineer. Is this the case and if so, how can I go about preventing this, if possible ? Or at least making it more difficult ? Thanks, George.

  • Looking for a simple alternative to Thread.Sleep

    - by George
    HI, During the development of my app, I was using Thread.Sleep to give our external devices some time to adjust to settings before making queries, as they are quite old and slow. I now want to replace these with something a bit more stylish and correct. Does anyone have a simple way to "wait" for a device rather than sleep, bearing in mind the device does not let us know when it is ready, so a wait is about as good as we can do !?? Regards, George.

  • Insert Record by Drag & Drop from ADF Tree to ADF Tree Table

    - by arul.wilson(at)oracle.com
    If you want to create record based on the values Dragged from ADF Tree and Dropped on a ADF Tree Table, then here you go.UseCase DescriptionUser Drags a tree node from ADF Tree and Drops it on a ADF Tree Table node. A new row gets added in the Tree Table based on the source tree node, subsequently a record gets added to the database table on which Tree table in based on.Following description helps to achieve this using ADF BC.Run the DragDropSchema.sql to create required tables.Create Business Components from tables (PRODUCTS, COMPONENTS, SUB_COMPONENTS, USERS, USER_COMPONENTS) created above.Add custom method to App Module Impl, this method will be used to insert record from view layer.   public String createUserComponents(String p_bugdbId, String p_productId, String p_componentId, String p_subComponentId){    Row newUserComponentsRow = this.getUserComponentsView1().createRow();    try {      newUserComponentsRow.setAttribute("Bugdbid", p_bugdbId);      newUserComponentsRow.setAttribute("ProductId", new oracle.jbo.domain.Number(p_productId));      newUserComponentsRow.setAttribute("Component1", p_componentId);      newUserComponentsRow.setAttribute("SubComponent", p_subComponentId);    } catch (Exception e) {        e.printStackTrace();        return "Failure";    }        return "Success";  }Expose this method to client interface.To display the root node we need a custom VO which can be achieved using below query.

  • Ideas for my MSc project and Google Summer of Code 2011

    - by Chris Wilson
    I'm currently putting together ideas for my master's project which I'll be working on over the summer, and I would like to be able to use this time to help Ubuntu in some way. I have the freedom to come up with pretty much any project in the field of software development/engineering provided it Is a substantial piece of software (for reference, I will be working on it for five full months) Solves a problem for more people than just myself I was hoping to use this project as an opportunity to get some experience with the underbelly of Linux, so that I can mention on my CV that I have 'experience in developing for *NIX in C++', which I'm noticing more and more companies are looking for these days, probably because stuff's moving to cloud servers and that's where Linux rules the roost. My problem is that, since I don't have the experience to begin with, I'm not sure what to do for such a project, and I was wondering if anyone could help me with this. I've noticed from Daniel Holbach's blog that Ubuntu participated in the Google Summer of Code 2010, and that project ideas for that can be found here. However, I have not been able to find anything related to Ubuntu and GSoC 2011, but I have noticed from the GSoC timeline that the list of mentoring organisations will not be published until March 18th. I have two questions here. Has Ubuntu applied to be a part of Summer of Code 2011, and what is the status of the 2010 project list linked to earlier. Were they all implemented or are there still some that can be picked up now, should I not participate in GSoC? I'd like to do something for Ubuntu, but I'd rather not spend my time reinventing the wheel.

  • 'Photo editor' and 'RAW editor' in Shotwell

    - by Chris Wilson
    The preference menu in Shotwell allows the user to specify both an 'External photo editor' and an 'External RAW editor', but I'm confused as to why two external editors would be required. I'm not a photographer, so this confusion may simply be a result of my ignorance, but I thought RAW images were unprocessed photographs, in which case two editors would be kinda redundant. Am I simply missing one of the finer details of photograph processing?

  • How to Automatically Backup Your Gmail Attachments With IFTTT

    - by Mark Wilson
    When it comes to getting things done quickly, automation is the name of the game. We’ve looked at IFTTT before, and a new batch of updates has introduced a number of options that can be used to automatically do things with files that are sent to your Gmail address. What could this be used for? Well the most obvious starting point is to simply create a backup of any files that you receive via email. This is useful if you find that you often reach the size limit for your inbox as it enables you to delete emails without having to worry about losing the associated files. Start by paying a visit to the IFTTT website and then either sign into an existing account or create a new one.

  • Is there a viable alternative to the agile development methodology? [closed]

    - by Eric Wilson
    The two predominant software-development methodologies are waterfall and agile. When discussing these two, there is often much focus on the particular practices that distinguish them (pair programming, TDD, etc. vs. functional spec, big up-front design, etc.) But the real differences are far deeper, in that these practices come from a philosophy. Waterfall says: Change is costly, so it should be minimized. Agile says: Change is inevitable, so make change cheap. My question is, regardless of what you think of TDD or functional specs, is the waterfall development methodology really viable? Does anyone really think that minimizing change in software is a viable option for those that desire to deliver valuable software? Or is the question really about what sort of practices work best in our situations to manage the inevitable change?

  • How to Skip the Start Screen and Boot to the Desktop in Windows 8.1

    - by Mark Wilson
    For almost everyone who made the upgrade, Windows 8 proved to be something of a disappointment for one reason or another. Windows 8.1 (or Windows Blue) was released to address many of the issues users had complained about including reintroducing the ability to boot straight to the desktop. Being able to boot to the desktop rather than the Start screen is something that people have been clammering for ever since the first preview versions of Windows 8 were unveiled. There have been various third-party tools released as numerous workarounds used to get around the problem, but now it is an option that is built directly into the operating system. You’ll need to have downloaded and installed the update in order to proceed, but once you have done this, things are very simple. When you have Windows up and running after the upgrade, right click an empty section of the taskbar and select properties to bring up the newly named “Taskbar and Navigation properties” dialog.  Move to the Navigation tab and look in the “Start screen” section in the lower half of the dialog. Check the box labelled ‘Go to the desktop instead of Start when I sign in” and click OK.

  • Gnome Keyring keeps asking for a password that doesn't exist

    - by Chris Wilson
    When ever I long into Ubuntu, I'm immediately presented with a dialogue that asks me to enter the password that will unlock Gnome Keyring, however I was never prompted to set this in the first place, and none of the passwords I've tried are effective. How can I disable these popups and just have Gnome Keyring unlocked when I log in in the same way that encrypted home directories are automatically mounted upon log in. FWIW, I'm set to auto log in, which may or may not be useful information. Btw, I've seen this question, and the accepted answer didn't work. I'd rather not uninstall Keyring Update 1: I've disabled automatic login but it still appears.

  • Why was Python's popularity so sudden? [closed]

    - by Eric Wilson
    Python first appeared in 1991, but it was somewhat unknown until 2004, if the TIOBE rankings quantify anything meaningful. What happened? What caused the interest in this 13 year old language to go through the roof? Is there a reason that Python wasn't considered a real competitor to Perl in its first decade of existence? Is there a reason that Python didn't continue in relative obscurity for another ten years? I personally think that Python is a very nice language, and I'm glad that I'm not the only one. But it doesn't have corporate backing or a killer feature that would explain a sudden rise to relevance. Does anyone know the story?

  • Display root node of Hierarchical Tree using ADF - EJB DC

    - by arul.wilson(at)oracle.com
    Displaying Employee (HR schema) records in Hierarchical Tree can be achieved in ADF-BC by creating custom VO and a Viewlink for displaying root node. This can be more easily done using  EJB-DC by just introducing a NamedQuery to get the root node.Here you go to get this scenario working.Create DB connection based on HR schema.Create Entity Bean from Employees Table.Add custom NamedQuery to Employees.java bean, this named query is responsible for fetching the root node (King in this example). @NamedQueries({  @NamedQuery(name = "Employees.findAll", query = "select o from Employees o"),  @NamedQuery(name = "Employees.findRootEmp", query = "select p from Employees p where p.employees is null")}) Create Stateless Session Bean and expose the Named Queries through the Session Facade.Create Datacontrol from SessionBean local interface.Create jspx page in ViewController project.Drop employeesFindRootEmp from Data Controls Palette as ADF Tree.Add employeesList as Tree level rule.Run page to see the hierarchical tree with root node as 'King'
