  • MySQL Date_Format based on today's date and another column?

    - by JM4
    I am aware of the MySQL Date_Format function but am looking to achieve the following: I have on column with a day date in 2 digit format (01-30). I am trying to update another date formatted field with the current year, the next month (m+1) and the day field mentioned previously. In PHP i would do this using mktime function but this must be done using mysql calls only. Is it possible to transform in this way?

  • Can I split a single SQL 2008 DB Table into multiple filegroups, based on a discriminator column?

    - by Pure.Krome
    Hi folks, I've got a SQL Server 2008 R2 database which has a number of tables. Two of these tables contains a lot of large data .. mainly because one of them is VARBINARY(MAX) and the sister table is GEOGRAPHY. (Why two tables? Read Below if you're interested***) The data in these tables are geospatial shapes, such as zipcode boundaries. Now, the first 70K odd rows are for DataType = 1 the rest 5mil rows are for DataType = 2 Now, is it possible to split the table data into two files? so all rows that are for DataType != 2 goes into File_A and DataType = 2 goes into File_B? This way, when I backup the DB, I can skip adding File_B so my download is waaaaay smaller? Is this possible? I guessing you might be thinking - why not keep them as TWO extra tables? Mainly because in the code, the data is conceptually the same .. it's just happens that I want to split the storage of this model data. It really messes up my model if I now how two aggregates in my model, instead of one. ***Entity Framework doesn't like Tables with GEOGRAPHY, so i have to create a new table which transforms the GEOGRAPHY to VARBINARY, and then drop that into EF.

  • Percentage function for a group based on another group.

    - by Jeff O
    I have two grouping levels in a report. Group A can have a Percentage() of the entire report and so can Group B, but I would like to know the Percentage() of Group A of Group B. Even if I code it, it seems like once the inner and outer groups have created their footers, I can't go back to to the inner group and set it's value. Example: Group A Total 50 Group A percentage of Report Total = 33% Group A Percentage of Group B Total = 33% but I want 50% Group B Total 100 Group B Percentage of Report Total = 66% Report Total 150

  • How can you deflect a direction/magnitude vector based on a direction/magnitude vector and a collided triangle?

    - by JeanOTF
    So, I have a Triangle-AABB collision algorithm and I have it returning the triangle that the AABB collided with. I was hoping with the 3 vectors of the triangle and the direction/magnitude of the movement would let me determine a deflected vector so that when you run against the wall at an angle you move slower, depending on the angle of collision, but along side the wall. This would remove the sticky collision problem with only moving when there is not a collision. Any suggestions or references would be greatly appreciated! Thanks.

  • How do I migrate from a basic plaintext password authentication to an OAuth based system?

    - by different
    Hello, Found out today that Twitter will be discontinuing its basic authentication for its API; the push is now towards OAuth but I don’t have a clue as to how to use it or whether it’s the right path for me. All I want to be able to do is post a tweet linking to the most recently published post when I hit publish. Currently I’m sending the login credentials for my Twitter account as plaintext, which I realise isn’t that secure but as my site is fairly small it isn’t an issue at least for now. I’m using this basic PHP code: $status = urlencode(stripslashes(urldecode("Test tweet"))); $tweetUrl = 'http://www.twitter.com/statuses/update.xml'; $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, "$tweetUrl"); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 2); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, "status=$status"); curl_setopt($curl, CURLOPT_USERPWD, "$username:$password"); $result = curl_exec($curl); $resultArray = curl_getinfo($curl); if ($resultArray['http_code'] == 200) { curl_close($curl); $this->redirect(""); } else { curl_close($curl); echo 'Could not post to Twitter. Please go back and try again.'; } How do I move from this to an OAuth system? Do I need to?

  • Best way to update/insert into a table based on a remote table.

    - by martilyo
    I have two very large enterprise tables in an Oracle 10g database. One table keeps the historical information of the other table. The problem is, I'm getting to the point where the records are just too many that my insert update is taking too long and my session is getting killed by the governor. Here's a pseudocode of my update process: sqlsel := 'SELECT col1, col2, col3, sysdate FROM table2@remote_location dpi WHERE (col1, col2, col3) IN ( SELECT col1, col2, col3 FROM table2@remote_location MINUS SELECT DISTINCT col1, col2, col3 FROM table1 mpc WHERE facility = '''||load_facility||''' )'; EXECUTE IMMEDIATE sqlsel BULK COLLECT INTO table1; I've tried the MERGE statement: MERGE INTO table1 t1 USING ( SELECT col1, col2, col3 FROM table2@remote_location ) t2 ON ( t1.col1 = t2.col1 AND t1.col2 = t2.col2 AND t1.col3 = t2.col3 ) WHEN NOT MATCHED THEN INSERT (t1.col1, t1.col2, t1.col3, t1.update_dttm ) VALUES (t2.col1, t2.col2, t2.col3, sysdate ) But there seems to be a confirmed bug on versions prior to Oracle 10.2.0.4 on the merge statement when doing a merge using a remote database. The chance of getting an enterprise upgrade is slim so is there a way to further optimize my first query or write it in another way to have it run best performance wise? Thanks.

  • What is the best way to generate XML from a C based CGI application using the SQLite API?

    - by Tommy
    Learning the basics of XML for the first time from W3C tutorials. How are most XML files generated? Does the server side application usually print a complete XML file to be parsed each time there is new data? I have a CGI application in C and it includes the SQLite API. Is the best way to do some sort of printf to a XML file (using my data from the database) so it can be parsed? Thanks.

  • [PHP, CSS, & ?] fixed width div, resizing text on the fly based on length

    - by Andrew Heath
    Let's say you've got a simple fixed-width layout that pulls a title from a MySQL database. CSS: #wrapper { width: 800px; } h1 { width: 100%; } HTML: <html> <body> <div id="wrapper"> <h1> $titleString </h1> </div> </body> </html> But the catch is, the length of the title string pulled from your MySQL database varies wildly. Sometimes it might be 10 characters, sometimes it might be 80. It's possible to establish a min & max character count. How, if at all possible, do I get the text-size of my <h1>$titleString</h1> to enlarge/decrease on-the-fly such that the string is only ever on one line and best fit to that line length? I've seen a lot of questions about resizing the div - but in my case the div must always be 100% (800px) and I want to best-fit the title. Obviously a maximum text-size value would have to be set so 5 character strings don't become gargantuan. Does anyone have a suggestion? I'm only using PHP/MySQL/CSS on this page at the moment, but incorporation of another language is fine if it means I can solve the problem. The only thing I can think of is a bruteforce approach whereby through trial and error I establish acceptable string character count ranges matched with CSS em sizes, but that'd be a pretty ugly implementation from the code side.

  • How does one record audio from a Javascript based webapp?

    - by username
    I'm trying to write a web-app that records WAV files (eg: from the user's microphone). I know Javascript alone can not do this, but I'm interested in the least proprietary method to augment my Javascript with. My targeted browsers are Firefox for PC and Mac (so no ActiveX). Please share your experiences with this. I gather it can be done with Flash (but not as a WAV formated file). I gather it can be done with Java (but not without code-signing). Are these the only options? @dominic-mazzoni I'd like to record the file as a WAV because because the purpose of the webapp will be to assemble a library of good quality short soundbites. I estimate upload will be 50 MB, which is well worth it for the quality. The app will only be used on our intranet. UPDATE: There's now an alternate solution thanks to JetPack's upcoming Audio API: See https://wiki.mozilla.org/Labs/Jetpack/JEP/18

  • Batch file to perform a looped search based on the line items of a text file.

    - by Tulga
    I have been reading great posts in this forum and got close to what I want to do but couldn't figure out the exact code. I want to create a windows batch file to do following: Perform a looped search for each line item of a text file (this is a list of keyword) to locate files in a a specific directory For this search partial match is okay. Each time a file is found, move it to a predefined directory (e.g. C:\temp\search_results) Thanks.

  • Performance of stored proc when updating columns selectively based on parameters?

    - by kprobst
    I'm trying to figure out if this is relatively well-performing T-SQL (this is SQL Server 2008). I need to create a stored procedure that updates a table. The proc accepts as many parameters as there are columns in the table, and with the exception of the PK column, they all default to NULL. The body of the procedure looks like this: CREATE PROCEDURE proc_repo_update @object_id bigint ,@object_name varchar(50) = NULL ,@object_type char(2) = NULL ,@object_weight int = NULL ,@owner_id int = NULL -- ...etc AS BEGIN update object_repo set object_name = ISNULL(@object_name, object_name) ,object_type = ISNULL(@object_type, object_type) ,object_weight = ISNULL(@object_weight, object_weight) ,owner_id = ISNULL(@owner_id, owner_id) -- ...etc where object_id = @object_id return @@ROWCOUNT END So basically: Update a column only if its corresponding parameter was provided, and leave the rest alone. This works well enough, but as the ISNULL call will return the value of the column if the received parameter was null, will SQL Server optimize this somehow? This might be a performance bottleneck on the application where the table might be updated heavily (insertion will be uncommon so the performance there is not a problem). So I'm trying to figure out what's the best way to do this. Is there a way to condition the column expressions with something like CASE WHEN or something? The table will be indexed up the wazoo as well for read performance. Is this the best approach? My alternative at this point is to create the UPDATE expression in code (e.g. inline SQL) and execute it against the server. This would solve my doubts about performance, but I'd rather leave this in a stored proc if possible.

  • Can I batch based on a Property (not just Items)?

    - by Josh Buedel
    I have a property group, like so: <PropertyGroup> <Platform>Win32;x64</Platform> </PropertyGroup> And I want to batch in an Exec task, like so: <Exec Command='devenv MySolution.sln /Build "Release|%(Platform)"' /> But of course, as written I get an error: error MSB4095: The item metadata %(Platform) is being referenced without an item name. Specify the item name by using %(itemname.Platform). Can I batch tasks on properties that are lists? I suppose I could hack it by creating a placeholder ItemGroup with metadata and batch on that.

  • How to make a Windows Mobile based WinForms .Net application easily changeable?

    - by Arthur
    I need to build a Win Mobile WinForms .Net application that once developed will be easy to morph or adjust to new user requirements quickly (including changes in GUI). The main objective is to minimize the development time (development to production roll-out effort). Also, a nice thing to have is to be able to test it in an automated way. The application must be able to: 1) Persist state (may use a local database); 2) Sync data across (via Radio or WiFi); 3) Exchange info with a desktop PC or a central server;

  • Why is there a margin at the top of my browser?

    - by fmz
    I have a web page that is displays differently in Firefox and Safari (IE testing yet to come). The page displays as expected in Safari, but there is a 50px margin between the body and the HTML that I can't determine what is causing it. Here is the CSS for the body: body { font-size: 13px; line-height: 1.333em; background: #f6eaae url(../_images/parchment-big.jpg) no-repeat center top; font-family: "Lucida Grande", Lucida, Verdana, sans-serif; color: #323232; } I would really appreciate some assistance in finding what is causing this difference. Ideally the Firefox version is better because it gives that extra breathing room at the top. Thanks.

  • Using Zend_Navigation, how do I create image-based navigation?

    - by SimpleCoder
    (I'm assuming my navigation should be in a layout script.) I have a navigation bar composed of rollover images. The image corresponding to the page that is active should be a different color, though. I do this by changing the image. My question is, where and how should I implement this using Zend_Navigation? Details: The menu itself is just a stack of divs that are floated to the left within a container. Each div has a background image. Thank you for your help,

  • In Ruby, is there are better way of selecting a constant (or avoiding the constant altogether) based

    - by Vertis
    Not sure the title fully describes the problem/question I'm trying to ask, sorry. I'm One of my fellow developers has created classes as such: class Widget attr_accessor :model_type ... end and: class ModelType MODEL1 = "model1" MODEL2 = "model2" MODEL3 = "model3" end Now he wants me to convert a retrieved string "MODEL1" to the constant. So that when he is referencing that model elsewhere he can use ModelType::MODEL1. Obviously I've got to convert from the string I'm being given with something like the following: case model_type when 'MODEL1' @model_type = ModelType::MODEL1 ... end I feel like this is clunky, so I'd like to know if there is a better DRYer way of providing this kind of functionality.

  • Pygame's Message-multiple lines?

    - by Jam
    I am using pygame and livewires (though I don't think that part is relevant here) to create a game. I've got the game working, but I'm trying to make something akin to a title screen before the game starts. However, it doesn't recognize when I try to make a new line appear. Here is what I have: begin_message=games.Message(value=""" Destroy the Bricks!\n In this game, you control a paddle,\n controlled by your mouse,\n and attempt to destroy all the rows of bricks.\n Careful though, you only have 1 life.\n Don't mess up! The game will start in\n 5 seconds.""", size=30, x=games.screen.width/2, y=games.screen.height/2, lifetime=500, color=color.white, is_collideable=False) games.screen.add(begin_message) The message appears on the screen, but the newline doesn't happen, so I can only read the first part of the message. Is there a way to make this message actually appear, or can I not use the 'Message' for this?
