  • Does SQL Server have any kind of magic undo feature?

    - by Andrew G. Johnson
    Long story short is I tried to quickly update a single row in SQL Server using the Management studio and just typed UPDATE table SET column='value' and forgot the WHERE other_column='other_value' portion. Went for lunch, came back and theres 15 unread emails waiting for me. Happened about an hour ago, waiting for the database guy to come back to see when the last backup was. There's no magic UNDO feature though is there?

  • SQL Server 2005 Blocking Problem (ASYNC_NETWORK_IO)

    - by ivankolo
    I am responsible for a third-party application (no access to source) running on IIS and SQL Server 2005 (500 concurrent users, 1TB data, 8 IIS servers). We have recently started to see significant blocking on the database (after months of running this application in production with no problems). This occurs at random intervals during the day, approximately every 30 minutes, and affects between 20 and 100 sessions each time. All of the sessions eventually hit the application time out and the sessions abort. The problem disappears and then gradually re-emerges. The SPID responsible for the blocking always has the following features: WAIT TYPE = ASYNC_NETWORK_IO The SQL being run is “(@claimid varchar(15))SELECT claimid, enrollid, status, orgclaimid, resubclaimid, primaryclaimid FROM claim WHERE primaryclaimid = @claimid AND primaryclaimid < claimid)”. This is relatively innocuous SQL that should only return one or two records, not a large dataset. NO OTHER SQL statements have been implicated in the blocking, only this SQL statement. This is parameterized SQL for which an execution plan is cached in sys.dm_exec_cached_plans. This SPID has an object-level S lock on the claim table, so all UPDATEs/INSERTs to the claim table are also blocked. HOST ID varies. Different web servers are responsible for the blocking sessions. E.g., sometimes we trace back to web server 1, sometimes web server 2. When we trace back to the web server implicated in the blocking, we see the following: There is always some sort of application related error in the Event Log on the web server, linked to the Host ID and Host Process ID from the SQL Session. The error messages vary, usually some sort of SystemOutofMemory. (These error messages seem to be similar to error messages that we have seen in the past without such dramatic consequences. We think was happening before, but didn’t lead to blocking. Why now?) No known problems with the network adapters on either the web servers or the SQL server. (In any event the record set returned by the offending query would be small.) Things ruled out: Indexes are regularly defragmented. Statistics regularly updated. Increased sample size of statistics on claim.primaryclaimid. Forced recompilation of the cached execution plan. Created a compound index with primaryclaimid, claimid. No networking problems. No known issues on the web server. No changes to application software on web servers. We hypothesize that the chain of events goes something like this: Web server process submits SQL above. SQL server executes the SQL, during which it acquires a lock on the claim table. Web server process gets an error and dies. SQL server session is hung waiting for the web server process to read the data set. SQL Server sessions that need to get X locks on parts of the claim table (anyone processing claims) are blocked by the lock on the claim table and remain blocked until they all hit the application time out. Any suggestions for troubleshooting while waiting for the vendor's assistance would be most welcome. Is there a way to force SQL Server to lock at the row/page level for this particular SQL statement only? Is there a way to set a threshold on ASYNC_NETWORK_IO waits only?

  • CSS: Setting width/height as Percentage minus pixels

    - by Mega Matt
    Hi all, I've seen this question asked in a couple other contexts on SO, but I thought it would be worth asking again for my particular case. I'm trying to create some re-usable CSS classes for more consistency and less clutter on my site, and I'm stuck on trying to standardize one thing I use frequently. I have a container div that I don't want to set the height for (because it will vary depending on where on the site it is), and inside it is a header div, and then an unordered list of items, all with CSS applied to them. It looks a lot like this: I want the unordered list to take up the remaining room in the container div, knowing that the header div is 18px tall. I just don't know how to specify the list's height as "the result of 100% minus 18px". Does anyone have any advice in this situation? Thanks very much.

  • Best way to be able to pick multiple colors/designs of symbols dynamically from flash

    - by Cyprus106
    Sorry the title's so convoluted... I must've tried for ten minutes to get a good, descriptive title! Basically, here's the scenario. Let's say a user can pick fifty different hat colors and styles to put on an avatar. The avatar can move his head around, so we'd need the same types of movements in the symbol for when that happens. Additionally, it gets which hat should be on the 'avatar' from a database. The problem is that we can't just make 50 different frames with a different hat on each. And each hat symbol will have the same movements, it'll just be different styles, colors and sizes. So how can I make one variable that is the HAT, that way we can just put the appropriate hat symbol into the variable and always be able to call Hat.gotoAndplay('tip_hat') or any other generic functions.... Does that make sense? Hope that's not too confusing. Sorry, I'm not great at the visual Flash stuff, but it's gotta be done! Thanks!

  • two arrays defining 2d coordinates, as array indices, in matlab/octave

    - by Jason
    Hi, I have a 2D array, call it 'A'. I have two other 2D arrays, call them 'ix' and 'iy'. I would like to create an output array whose elements are the elements of A at the index pairs provided by x_idx and y_idx. I can do this with a loop as follows: for i=1:nx for j=1:ny output(i,j) = A(ix(i,j),iy(i,j)); end end How can I do this without the loop? If I do output = A(ix,iy), I get the value of A over the whole range of (ix)X(iy). Thank you, Jason

  • print css: fit in one page

    - by user281521
    Hi. In my page there's only one image. Kind of 1500x3000 px. In the printer, I need that this image's maximum width to be the width of the page, so I did: width 100% in the css, and it works. But the height... the old bullshit of height 100% will never work. Because it always will be 100% of the parent container, then someone must have height defined. Or html or body. So, my question is: make this image fit in one page. Any ideas?

  • OpenPeak Flash app XMLSocket Security Problem

    - by Kira
    We're trying to create an app for OpenPeak. The Flash app will act as a client to a Java server on another computer on another domain. The Flash app client connects via XMLSocket. The Java Server uses ServerSocket to receive a request and send back a message. In order to trust the server, the Flash client needs a socket master policy file to tell it that the server comes from a trustworthy domain. According to an article on Adobe, when a connection has succeeded, the Flash client automatically requests the cross-domain policy or socket master policy file on port 843. Still, even when we implement it according to the tutorials and recommendations we have read, the Flash client continues to throw the following security error: SecurityErrorEvent type="securityError" bubbles=false cancelable=false eventPhase=2 text="Error #2048" We've tried logging the policy file request during testing to see if there was any call made to port 843. There was not. Interestingly, even without a policy file, the Flash client still manages to send the first data message to the server successfully. It's just when the server tries to send back a reply that the entire thing hangs for about 10 seconds before the security error above is displayed. Any ideas / suggestions?

    I need to get a path to the GIT on Max OS X 10.6 using Python 2.6.1 into script variables. I use this code for that: r = subprocess.Popen(shlex.split("which git"), stdout=subprocess.PIPE) print r.stdout.read() but the problem is that output is empty (I tried stderr too). It works fine with another commands such as pwd or ls. Can anyone help me with that?

  • Do you code variables in your language?

    - by Phil Hannent
    I am just working on a project where the library has an object with the property color, however being British I always use colour when writing variables and properties. I also just found some legacy code where the British developer used color in a variable name. Is American English the default for development now?

  • Spamassassin one-liner to tag & move mail with an X-Spam-Flag: YES to a new directory?

    - by ane
    Say you have a directory with tens of thousands of messages in it. And you want to separate the spam from the non-spam. Specifically, you would like to: Run spamassassin against the directory, tagging each message with an X-Spam-Flag: YES if it thinks it's spam Have a tcsh shell or perl one-liner grep all mail with the flag and move those mails to /tmp/spam What command can you run to accomplish this? For example, some pseudocode: /usr/local/bin/spamassassin -eL ./Maildir/cur/* | grep "X-Spam-Flag: YES" | mv %1 /tmp/spam

  • How to login without entering username and password

    - by torbengb
    I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious. I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users. Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways? (I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password. Yes, you're right. But that's not what this question is about. Thanks.)

  • Porting VB6 app to VB.Net: Can anyone ballpark how much effort this is?

    - by Robusto
    In 2002 I did a pretty large VB6 app for a client. It used a lot of UserControls and a 3rd party menu control (for putting icons next to menu names). It had dynamically "splittable" panels, TreeViews with multi-state checkboxes, etc. A very rich UI. My total time on the project was about 500 hours, which the client graciously let me spread over a whole month. (Yeah, it was that kind of job.) They were very happy, though, and they paid the bill on time with no argument. So after having no contact with them for years, they suddenly call and wonder if I can update the app to .Net for them. My initial reaction is just to decline, since I don't use VB.Net. And having read a bunch of posts on SO about the difficulties of porting, etc., etc., I'm even more inclined to decline, so to speak. Still, before I tell them no I am interested in roughly quantifying the effort it would take. I would love to hear from anyone who has done this kind of thing and has a feel for how much work it is. Was it: Significantly less than the effort you used on the original? Somewhat less than the effort you used on the original? The same as the effort you used on the original? More? A lot more? Please only respond if you have actually done this kind of port. And the answer doesn't have to be exact, since I really am only trying to ballpark this. My feeling is that the effort will be at least as much as it took for the original, if not more. But I could be wrong. Thanks for any help.
