  • Group functions of outer query inside inner query

    - by superdario
    Hello, I'm using Oracle. I'm trying to compose something like this: SELECT trans_type, (SELECT parameter_value FROM transaction_details WHERE id = MAX(t.trans_id)) FROM (SELECT trans_id, trans_type FROM transactions) t GROUP BY trans_type So, I am trying to use a result of grouping inside an inner query. But I am getting the error that I cannot use a group function inside the inner query: ORA-00934: group function is not allowed here Can you offer an alternative other than resorting to another outer query?

  • Resources for learning about Threading

    - by Incubuss
    I've spent the last year learning and using Java in university but we didn't do much (read: anything) in terms of Threading. We do some next year but I'm hopeful I'll be able to get a head start over the summer. What are the best resources for learning about and getting to grips with Threading?

  • I get 2014 Cannot execute queries while other unbuffered queries are active when doing exec with PDO

    - by Itay Moav
    I am doing a PDO::exec command on multiple updates: $MyPdo->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY,true); $MyPdo->exec("update t1 set f1=1;update t2 set f1=2"); I am doing it inside a transaction, and I keep getting: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. those are the only query/ies

  • flash's "useHandCursor = true" not working for Chrome on Mac

    - by fucrate
    I'm developing a flash game using the default SimpleButton object for my buttons and the hand cursor is working just fine on PC Chrome and Firefox and Safari for Mac, but Chrome on Mac is not letting me swap the default cursor for the hand cursor. I've even set useHandCursor to true for every button I add a click event to and am still getting nothing. We've got no other rollover events, so it's important that the cursor switch. Anyone else run into this and have a lil-fixy / workaround?

  • Is there any sence in performing binary AND with a number where all bits are set to 1

    - by n535
    Greetings everybody. I have seen examples of such operations for so many times that i began to think that i am getting something wrong with binary arithmetics. Is there any sense to perform the following: byte value = someAnotherByteValue & 0xFF; I don't really understand this, because it does not change anything anyway. Thanks for help. P.S. I was trying to search for information both elsewhere and here, but unsuccessfully.

  • use viewengine only within certain area

    - by Daniel Powell
    Is it possible to use a custom view engine for a specific area only? I have tried public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Forms_default", "Forms/{client}/{controller}/{action}/{id}", new { client="Generic",action = "Index", id = UrlParameter.Optional } ); ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new ClientSpecificViewEngine()); } Within my area but this seems to be a site wide affect as I'm getting errors specific to the custom view engine when visiting pages outside the area.

  • Looking for Fiddler2 help. connection to gateway refused? Just got rid of a virus

    - by John Mackey
    I use Fiddler2 for facebook game items, and it's been a great success. I accessed a website to download some dat files I needed. I think it was eshare, ziddu or megaupload, one of those. Anyway, even before the rar file had downloaded, I got this weird green shield in the bottom right hand corner of my computer. It said a Trojan was trying to access my computer, or something to that extent. It prompted me to click the shield to begin anti-virus scanning. It turns out this rogue program is called Antivirus System Pro and is pretty hard to get rid of. After discovering the rogue program, I tried using Fiddler and got the following error: [Fiddler] Connection to Gateway failed.Exception Text: No connection could be made because the target machine actively refused it 127.0.0.1:5555 I ended up purchasing SpyDoctor + Antivirus, which I'm told is designed specifically for getting rid of these types of programs. Anyway, I did a quick-scan last night with spydoctor and malware bytes. Malware picked up 2 files, and Spydoctor found 4. Most were insignificant, but it did find a worm called Worm.Alcra.F, which was labeled high-priority. I don’t know if that’s the Anti-Virus Pro or not, but SpyDoctor said it got rid of all of those successfully. I tried to run Fiddler again before leaving home, but was still getting the "gateway failed" error. Im using the newest version of firefox. When I initially set up the Fiddler 2.2.8.6, I couldn’t get it to run at first, so I found this faq on the internet that said I needed to go through ToolsOptionsSettings and set up an HTTP Proxy to 127.0.0.1 and my Port to 8888. Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor says the bad stuff is gone, so maybe the rogue program made some type of change in my fiddler that I could just reset or uncheck or something like that? Or will I need to completely remove fiddler and those dat files and rar files I downloaded? Any help would be greatly appreciated. Thanks for your time.

    Hi! I want to use the systems available windows media player visualizers in my app. Apperently visualizers expose an IWMPEffects interface to the world. My question is how do I enumerate and create instances to the available visualizers on my system? Probably it's just a process of getting the cslid of the visualizers and then create the instance with CoCreateInstance. However I have no idea how to get these clsid's! Thanks!

  • Is the WebAii test automation framework dead?

    - by RyanW
    Is the WebAii framework still available and free? Am I just missing it? After putting it off for too long, I've finally started automated UI testing on my current project. I had WebAii from ArtOfTest on my list to look at, but it looks like it's been killed off by Telerik and now they're asking $1500 for their new WebUI test studio. I can't find anything definitive on Telerik's site, too much marketing. But, it seems to be pretty clear.
