• Remove file from history completely

  - by Iain

  A colleague has done a few things I told them not to do: forked the origin repo online cloned the fork, added a file that shouldn't have been added to that local repo pushed this to their fork I've then: merged the changes from the fork and found the file I want to remove this from: my local repo the fork their local repo I have a solution for removing something from the history, taken from Remove file from git repository (history). What I need to know is, should my colleague also go through this, and will a subsequent push remove all info from the fork? (I'd like an alternative to just destroying the fork, as I'm not sure my colleague will do this) SOLUTION: This is the shortest way to get rid of the files: check .git/packed-refs - my problem was that I had there a refs/remotes/origin/master line for a remote repository, delete it, otherwise git won't remove those files (optional) git verify-pack -v .git/objects/pack/#{pack-name}.idx | sort -k 3 -n | tail -5 - to check for the largest files (optional) git rev-list --objects --all | grep a0d770a97ff0fac0be1d777b32cc67fe69eb9a98 - to check what files those are git filter-branch --index-filter 'git rm --cached --ignore-unmatch file_names' - to remove the file from all revisions rm -rf .git/refs/original/ - to remove git's backup git reflog expire --all --expire='0 days' - to expire all the loose objects (optional) git fsck --full --unreachable - to check if there are any loose objects git repack -A -d - repacking the pack git prune - to finally remove those objects

• Android - How to circular zoom/magnify part of image?

  - by IZI_Shadow_IZI

  I am trying to allow the user to touch the image and then basically a cirular magnifier will show that will allow the user to better select a certain area on the image. When the user releases the touch the magnified portion will dissapear. This is used on several photo editing apps and I am trying to implement my own version of it. The code I have below does magnify a circular portion of the imageview but does not delete or clear the zoom once I release my finger. I currently set a bitmap to a canvas using canvas = new Canvas(bitMap); and then set the imageview using takenPhoto.setImageBitmap(bitMap); I am not sure if I am going about it the right way. The onTouch code is below: zoomPos = new PointF(0,0); takenPhoto.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { int action = event.getAction(); switch (action) { case MotionEvent.ACTION_DOWN: zoomPos.x = event.getX(); zoomPos.y = event.getY(); matrix.reset(); matrix.postScale(2f, 2f, zoomPos.x, zoomPos.y); shader.setLocalMatrix(matrix); canvas.drawCircle(zoomPos.x, zoomPos.y, 20, shaderPaint); takenPhoto.invalidate(); break; case MotionEvent.ACTION_MOVE: zoomPos.x = event.getX(); zoomPos.y = event.getY(); matrix.reset(); matrix.postScale(2f, 2f, zoomPos.x, zoomPos.y); canvas.drawCircle(zoomPos.x, zoomPos.y, 20, shaderPaint); takenPhoto.invalidate(); break; case MotionEvent.ACTION_UP: //clear zoom here? break; case MotionEvent.ACTION_CANCEL: break; default: break; } return true; } });

• Cannot locate record in delphi ADO query

  - by Danatela

  I can't locate any record in TADOQuery using PK. First, I was trying to use standard Locate method: PPUQuery.Locate('ID', SpPlansQuery['PPONREC'], []); It always returns False, but manual search (passing the whole query matching ID with given PPONREC which is really slow) finds the desired row. I tried using loPartialKey and switched CursorLocation of query to clUseServer, but it didn't help. Next, I tried to filter my PPUQuery: PPUQuery.Filter := 'ID = ' + VarToStr(SpPlansQuery['PPONREC']); PPUQuery.Filtered := True; PPUQuery.First; But after that the PPUQuery.Eof is True and PPUQuery.RecordCount equals 0. Underlying database is Oracle 9 and the ID is of type INTEGER and is PK of table TPORDER_CMK. PPUQuery.SQL is: SELECT tp.*, la.*, lm.*, ld.*, ld1.*, to_cmk.* FROM ppu_plan.tporder_cmk tp JOIN PPU_PLAN.LARTICLES la ON TP.ARTICLE = LA.ID JOIN PPU_PLAN.LMATERIAL lm ON TP.MATERIAL = lm.id JOIN PPU_PLAN.LCADEP ld ON TP.CADEP = LD.ID JOIN PPU_PLAN.LCADEP ld1 ON TP.PRODUCER = LD1.ID JOIN PPU_PLAN.TORDER_CMK to_cmk ON TP.order_id=TO_cmk.ID WHERE TP.PLAN_ID = :pplan_id What should I try next and how to solve this problem?

• Problem with unlink() in php!

  - by Holicreature

  I'm creating a temp image always named 1.png under specific folder and once i read the image_contents and process, i use unlink() to delete that specific image from that folder. But sometimes the image file is not deleted and the same image is file is read and processed. That script is working otherwise fine... There is no permission related issues , as the files are deleted sometimes... Will there be any issue when the script is repeatedly called and the image with the name is already present and not deleted etc.. ??? Please suggest me what would be the problem extension_loaded('ffmpeg'); $max_width = 120; $max_height = 72; $path ="/home/fff99/public_html/temp/"; ..... ..... $nname = "/home/friend99/public_html/temp/".$imgname; $fileo = fopen($nname,"rb"); if($fileo) { $imgData = addslashes(file_get_contents($nname)); .... ... .. } unlink('$nname');

• Database PK-FK design for future-effective-date entries?

  - by Scott Balmos

  Ultimately I'm going to convert this into a Hibernate/JPA design. But I wanted to start out from purely a database perspective. We have various tables containing data that is future-effective-dated. Take an employee table with the following pseudo-definition: employee id INT AUTO_INCREMENT ... data fields ... effectiveFrom DATE effectiveTo DATE employee_reviews id INT AUTO_INCREMENT employee_id INT FK employee.id Very simplistic. But let's say Employee A has id = 1, effectiveFrom = 1/1/2011, effectiveTo = 1/1/2099. That employee is going to be changing jobs in the future, which would in theory create a new row, id = 2 with effectiveFrom = 7/1/2011, effectiveTo = 1/1/2099, and id = 1's effectiveTo updated to 6/30/2011. But now, my program would have to go through any table that has a FK relationship to employee every night, and update those FK to reference the newly-effective employee entry. I have seen various postings in both pure SQL and Hibernate forums that I should have a separate employee_versions table, which is where I would have all effective-dated data stored, resulting in the updated pseudo-definition below: employee id INT AUTO_INCREMENT employee_versions id INT AUTO_INCREMENT employee_id INT FK employee.id ... data fields ... effectiveFrom DATE effectiveTo DATE employee_reviews id INT AUTO_INCREMENT employee_id INT FK employee.id Then to get any actual data, one would have to actually select from employee_versions with the proper employee_id and date range. This feels rather unnatural to have this secondary "versions" table for each versioned entity. Anyone have any opinions, suggestions from your own prior work, etc? Like I said, I'm taking this purely from a general SQL design standpoint first before layering in Hibernate on top. Thanks!

• get the right id of a record in database in each click on the edit button

  - by kawtousse

  hi every one, i am facing a big problem right now. I have a html table in each row i have a button called edit allowing user to relod the form with parameter that he has selected. for this i define a hidden type to get the id of the record in database to access to various colonne and to refresh the form with those parameters. My challenge now is how to get the right id in every click on the edit button to let me after to get the right record and to update it in the data base. I am preceeding like the following: retour.append("<td style=border-right:#FFF bordercolor=#FFFFFF>"); retour.append("<input type=\"hidden\" id=\"id_"+nomTab+"_"+compteur+"\" value=\""+object.getIdDailyTimeSheet()+"\" name=\"hd"+compteur+"\" />"); retour.append("<button id=edit name=edit type=button onClick= editarow()>"); retour.append("<img src=edit.gif />"); retour.append("</button>"); retour.append("</td>"); i realise the submit in javascript and i want to get the idDailyTimesheet everyonce the user click the submit button. thanks for help.

• Simple Oracle File repository with folder hierarchy

  - by Ope

  I have an application that stores large amount of files (XML and binary) in folder hierarchies. Currently the main method is storing them in file system or using a legacy CMS, which we want to get rid of. The CMS supports Oracle and a customer wants to keep the files in Oracle because of enterprise policies (backup etc.) The question is: Is there a simple implementation of file repository with folder hierarchy for Oracle? What I am looking for is a small .Net component or example code (PL/SQL and/or .Net) that would have the following methods: Create, Delete, Exists Folder CRUD file Move and potentially Copy file or directory Access to files and folders with paths like "/root/folder1/folder2/file.xml" Ability to get all the files and folders in a folder and potentially also the entire directory tree Tree traversal, getting the parent, all children etc. needs to be fast. I need the implementation in .Net, but if it was just the stored procedures, I could create the .Net calling code. I have pointers to generic articles for creating hierarchies in DB, so if I need to do it from scratch, I know where to start. What I am asking here, is there already an implementation that I could take without doing this from scratch? It seems like such a generic requirement... If the answer is a CMS, Document management system or such it should be Open Source or at least quite cheap (some hundreds / server) and it should be possible to deploy it XCopy - hopefully only couple of DLL:s. I do not need - or want - a full featured big CMS with dozens of dlls and especially not an msi-installation. I have tried to google this, but the words "repository", "CMS", "file hierarchy" etc. give so many answers, the searches are pretty much useless. Thanks, OPe

• What is the "un-tab" sequence in (g)Vim?

  - by OwenP

  This is an annoyance I've had for a long time. (Nitpicky section: I prefer 4 space characters to tab characters. It's a lot easier to type "tab" instead of explaining that. When I say "tab", I mean "the action that happens when you press the tab key" which is probably more simply stated as "increase indentation".) I'm using smartindent while editing a document where indentation has some significance. In "dumb" windows text editors I can press Shift+Tab to remove a tab or, more appropriately, decrease the indentation level of the current line. I can't figure out how to do this from edit mode in Vim; Shift+Tab seems to count just the same as Tab. I know in Command mode << will decrease indentation. I want the equivalent in edit mode. These are the solutions I've found so far and why I don't like them, one in particular may be the key to the answer. Use Notepad++ or some other dumb editor. I've done this for a couple of years but I really miss Vim. Exit edit mode, use <<, enter edit mode. This just puts the cursor at column 0; if I wanted this I wouldn't have tried smartindent. Stop using smartindent. I don't decrease indent as often as I need to keep the same indent level; this would be a loss of productivity. The left arrow key seems to decrease the indent by one level. I'd rather something I can do without leaving the home row. This is the most promising choice. Maybe there's an option I can set? Maybe I can rebind left arrow to something? (If it requires rebinding please explain in detail; I've never delved into reconfiguring (g)Vim.

• Text being printed twice in uitableview

  - by user337174

  I have created a uitableview that calculates the distance of a location in the table. I used this code in cell for row at index path. NSString *lat1 = [object valueForKey:@"Lat"]; NSLog(@"Current Spot Latitude:%@",lat1); float lat2 = [lat1 floatValue]; NSLog(@"Current Spot Latitude Float:%g", lat2); NSString *long1 = [object valueForKey:@"Lon"]; NSLog(@"Current Spot Longitude:%@",long1); float long2 = [long1 floatValue]; NSLog(@"Current Spot Longitude Float:%g", long2); //Getting current location from NSDictionary CoreDataTestAppDelegate *appDelegate = (CoreDataTestAppDelegate *) [[UIApplication sharedApplication] delegate]; NSString *locLat = [NSString stringWithFormat:appDelegate.latitude]; float locLat2 = [locLat floatValue]; NSLog(@"Lat: %g",locLat2); NSString *locLong = [NSString stringWithFormat:appDelegate.longitude]; float locLong2 = [locLong floatValue]; NSLog(@"Long: %g",locLong2); //Location of selected spot CLLocation *loc1 = [[CLLocation alloc] initWithLatitude:lat2 longitude:long2]; //Current Location CLLocation *loc2 = [[CLLocation alloc] initWithLatitude:locLat2 longitude:locLong2]; double distance = [loc1 getDistanceFrom: loc2] / 1600; NSMutableString* converted = [NSMutableString stringWithFormat:@"%.1f", distance]; [converted appendString: @" m"]; It works fine apart from a problem i have just discovered where the distance text is duplicated over the top of the detailed text label when you scroll beyond the height of the page. here's a screen shot of what i mean. Any ideas why its doing this?

• [Zend Framework] Forms and success output

  - by rasouza

  Well, It's a beginer's question but I really don't know what is the best way. I have a basic CRUD (Create, Retrieve, Update and Delete) in my project and I'd like to output some message if succeded or not in a div inside the same page. So, basically, I have a form which action is setted to the same page and I have a div #statusDiv below this same form which I'd like to output something like Register included with success. What is the best way for doing this? Set a flag in the controller $this->view->flagStatus = 'message' then call it in the view? Just to make it more clear. It's my code: //IndexController.php indexAction() ... //Check if there's submitted data if ($this->getRequest()->isPost()) { ... $registries->insert($data); $this->view->flagStatus = 'message'; $this->_redirect('/'); } Then my view: .... <?php if ($this->flagStatus) { ?> <div id="divStatus" class="success span-5" style="display: none;"> <?php echo $this->flagStatus; ?> </div> <?php } ?> ....

• Batch file recursively find files and rar them

  - by b1gf00t

  Hi there, I have a Parent Directory which hosts many sub directories, and in every sub directory there is .mpg movies. Some of the directories might contain one or more .mpg movies. I would like to automate the process below, which I have been doing manually. Step One If the directory has more than 1 .mpg file, I create separates directories for each and move each file into its directory, naming the directory as per the name of the file. Step Two I rar each video file in its directory as per one of my profiles, by that it splits the movie into 50MB parts, test the archive, delete the source, and instructs winrar to wait if another rar is executing. I am doing this so I can queue jobs manually. Step Three After having all the rars in the sub directories, I start creating a checksum for every directory, therefore leaving checksum.sfv in every directory. Step Four I copy the parent folder and its sub directories to my external drives. I was hoping that someone could assist me in creating a script. I was able to automate the process of creating directories as per the name of the file, and moving the file. However, I never succeeded in automating Step two. I am using the below software Winrar from rarlabs exf from exactfile Appreciate your assistance.

• How to debug properly and find causes for crashes?

  - by Newbie

  I dont know what to do anymore... its hopeless. I'm getting tired of guessing whats causing the crashes. Recently i noticed some opengl calls crashes programs randomly on some gfx cards. so i am getting really paranoid what can cause crashes now. The bad thing on this crash is that it crashes only after a long time of using the program, so i can only guess what is the problem. I cant remember what changes i made to the program that may cause the crashes, its been so long time. But luckily the previous version doesnt crash, so i could just copypaste some code and waste 10 hours to see at which point it starts crashing... i dont think i want to do that yet. The program crashes after i make it to process the same files about 5 times in a row, each time it uses about 200 megabytes of memory in the process. It crashes at random times while and after the reading process. I have createn a "safe" free() function, it checks the pointer if its not NULL, and then frees the memory, and then sets the pointer to NULL. Isn't this how it should be done? I watched the task manager memory usage, and just before it crashed it started to eat 2 times more memory than usual. Also the program loading became exponentially slower every time i loaded the files; first few loads didnt seem much slower from each other, but then it started rapidly doubling the load speeds. What should this tell me about the crash? Also, do i have to manually free the c++ vectors by using clear() ? Or are they freed after usage automatically, for example if i allocate vector inside a function, will it be freed every time the function has ended ? I am not storing pointers in the vector. -- Shortly: i want to learn to catch the damn bugs as fast as possible, how do i do that? Using Visual Studio 2008.

• mysql join with conditional

  - by Conor H

  Hi There, I am currently working on a MySQL query that contains a table: TBL:lesson_fee -fee_type_id (PRI) -lesson_type_id (PRI) -lesson_fee_amount this table contains the fees for a particular 'lesson type' and there are different 'fee names' (fee_type). Which means that there can be many entries in this table for one 'lesson type' In my query I am joining this table onto the rest of the query via the 'lesson_type' table using: lesson_fee INNER JOIN (other joins here) ON lesson_fee.lesson_type_id = lesson_type.lesson_type_id The problem with this is that it is currently returning duplicate data in the result. 1 row for every duplicate entry in the 'lesson fee' table. I am also joining the 'fee type' table using this 'fee_type_id' Is there a way of telling MySQL to say "Join the lesson_fee table rows that have lesson_fee.lesson_type_id and fee_type_id = client.fee_type_id". UPDATE: Query: SELECT lesson_booking.lesson_booking_id,lesson_fee.lesson_fee_amount FROM fee_type INNER JOIN (lesson_fee INNER JOIN (color_code INNER JOIN (employee INNER JOIN (horse_owned INNER JOIN (lesson_type INNER JOIN (timetable INNER JOIN (lesson_booking INNER JOIN CLIENT ON client.client_id = lesson_booking.client_id) ON lesson_booking.timetable_id = timetable.timetable_id) ON lesson_type.lesson_type_id = timetable.lesson_type_id) ON horse_owned.horse_owned_id = lesson_booking.horse_owned_id) ON employee.employee_id = timetable.employee_id) ON employee.color_code_id = color_code.color_code_id) ON lesson_fee.lesson_type_id = lesson_type.lesson_type_id) ON lesson_fee.fee_type_id = client.fee_type_id WHERE booking_date = '2010-04-06' ORDER BY lesson_booking_id ASC How do I keep the format(indentation) of my query?

• jqgrid questions

  - by user508518

  Hi All- I recently posted a question on SO on freezing columns in jqgrid(http://stackoverflow.com/questions/4586924/jqgrid-freeze-columns). I got the following solution to be working in IE8, but its not all perfect: I set to use two css classes, one for header and other one for the rows like below: .jqgridbodyLock{ position:relative; left: expression(parentNode.parentNode.parentNode.parentNode.parentNode.scrollLeft); z-index: 10; } .jqgridheaderLocked{ position:relative; left: expression(parentNode.parentNode.parentNode.parentNode.parentNode.scrollLeft); /* IE5+ only */ z-index:30; } Then in colModel, I used the property classes {name:'column1', width:100, index:'column1', sorttype:"string", classes:'jqgridbodyLock'},//lock the body row and to lock the respective header I used code as below: $("#grid").setLabel("column1","column1","jqgridheaderLocked"); Though the solution works, I have the following problems: 1) The header values shake a lot when scrolling to the right though they remain frozen 2) The body values of the frozen column disappear when the cursor is taken out of the grid. 3) How to lock a normal table in firefox. I see that 'expression' is exclusive only to IE browser Thanks a lot

• Vacancy Tracking Algorithm implementation in C++

  - by Dave

  I'm trying to use the vacancy tracking algorithm to perform transposition of multidimensional arrays in C++. The arrays come as void pointers so I'm using address manipulation to perform the copies. Basically, there is an algorithm that starts with an offset and works its way through the whole 1-d representation of the array like swiss cheese, knocking out other offsets until it gets back to the original one. Then, you have to start at the next, untouched offset and do it again. You repeat until all offsets have been touched. Right now, I'm using a std::set to just fill up all possible offsets (0 up to the multiplicative fold of the dimensions of the array). Then, as I go through the algorithm, I erase from the set. I figure this would be fastest because I need to randomly access offsets in the tree/set and delete them. Then I need to quickly find the next untouched/undeleted offset. First of all, filling up the set is very slow and it seems like there must be a better way. It's individually calling new[] for every insert. So if I have 5 million offsets, there's 5 million news, plus re-balancing the tree constantly which as you know is not fast for a pre-sorted list. Second, deleting is slow as well. Third, assuming 4-byte data types like int and float, I'm using up actually the same amount of memory as the array itself to store this list of untouched offsets. Fourth, determining if there are any untouched offsets and getting one of them is fast -- a good thing. Does anyone have suggestions for any of these issues?

• PHP & MySQL storing multiple values in a database.

  - by R.I.P.coalMINERS

  I'm basically a front end designer and new to PHP and MySQL but I want a user to be able to store multiple names and there meanings in a MySQL database table named names using PHP I will dynamically create form fields with JQuery every time a user clicks on a link so a user can enter 1 to 1,000,000 different names and there meanings which will be stored in a table called names. All I want to know is how can I store multiple names and there meanings in a database and then display them back to the user for them to edit or delete using PHP MySQL? I created the MySQL table already. CREATE TABLE names ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, userID INT NOT NULL, name VARCHAR(255) NOT NULL, meaning VARCHAR(255) NOT NULL, PRIMARY KEY (id) ); Here is the HTML. <form method="post" action="index.php"> <ul> <li><label for="name">Name: </label><input type="text" name="name" id="name" /></li> <li><label for="meaning">Meaning: </label><input type="text" name="meaning" id="meaning" /></li> <li><input type="submit" name="submit" value="Save" /> <input type="hidden" name="submit" value="true" /></li> </ul> </form>

  Hi guys, I have a very simple css file for my Asp.Net MVC application. body { font-family: Arial, Helvetica, sans-serif; font-size: x-small; color: #663300; } input { font-family: Arial, Helvetica, sans-serif; font-size: x-small; background-color: #FFFF99; color: #CC6600; border: 1px solid #808000; } .headerRow { background-color: #FFFFCC; border-style: none none dotted none; border-bottom-width: 1px; border-bottom-color: #800000; font-family: Arial, Helvetica, sans-serif; font-size: x-small; font-weight: bold; text-align: left; vertical-align: middle; text-transform: uppercase; } The Body is working well in both... as is the input. However, the headerRow isn't working in FF, yet works well in IE. Here it is, being used: <table width="700" border="0" cellspacing="1" cellpadding="2"> <tr class="headerRow"> <td> Transaction Date </td> <td> Type </td> <td> Category </td> <td> Budget Assignment </td> <td> Cost Center </td> <td align="right"> Amount </td> </tr> The header row just displays as normal body text though...

• Rails HTML Table update fields in mongo with AJAX

  - by qwexar

  I'm building a Rails app backed by mongodb using mongoid. It's a one page app, with a HTML table, every field for every row of which, needs to be editable without refreshing the page. This is your usual Rails view ( like many in rails casts ) showing a table with rows and columns containing data. For example. I'm showing cars, and showing their make, model and notes They way I'm doing this is by appending _id of a mongo document to every column and marking it's field name in html id too. Then I pick up the value for $("#id") and send it to rails controller via AJAX and run @car.update_attributes method accordingly. Currently, one of my rows looks like this. <tr> <td id=<%= car.id %>_make> <%= car.make %> </td> <td id=<%= car.id %>_model> <%= car.model %> </td> <td id=<%= car.id %>_notes> <%= car.notes %> </td> </tr> // my function which is called onChange for every column function update_attributes(id){ var id = id.split[0]; var attribute = id.split[1]; $.ajax("sending id and attribute to rails controller"); } Is there any built it Rails magic which would let me update only a field in a model without refreshing the page? or. Is there a Rails plugin for this?

• Aggregation, Association and Composition (examples of code given)

  - by Bukocen

  I have such a simple example: public class Order { private ArrayList<Product> orders = new ArrayList<Product>(); public void add(Product p) { orders.add(p); } } Is it aggregation or composition? I guess it's composition, because orders will be delated after delete of Order, right? Unfortunately it was a task and answer was different;/ Do you know why? second problem: public class Client extends Person { String adress = ""; Orders orders = new Orders(); public Client(String n, String sn) { name = n; surName = sn; } public String getAddress() { return adress; } public Orders getOrders() { return this.orders; } } Is it Association between Client and Orders? My teacher told me that this is association, but I was wondering why it's not a aggregation/composition - he told me that aggregation or composition occur only when one class contains few instances of different class - is that right? I guess not, because e.g. car contains ONE wheel and it's aggregation I guess? What type of relation is that and why? Greetings

• Removing random object from parent CCprite

  - by Natty

  probably this is a simple problem to solve, since I'm quite new. I have a scene with a waiter holding a tray of food (the food is a random CCSprite choosen from an array) each time he comes onscreen he holds a new piece of food (the user touches the food and the waiter walks off to return again with a new piece of food however I cant seem to delete the old peice of food from the screen as it says the child is already added... any help would be great -(id) init { ///other code then... waiterOnSCreen = [CCSprite spriteWithSpriteFrameName:@"CatUP.png"]; waiterOnSCreen.position = ccp(CatOffSCreenPosX, catXpos); [self addChild:waiterOnSCreen z:0]; //moving the waiter // the random food sprite is added later to the waiter // [waiterOnSCreen addChild:myRandomSprite]; } -(void)LoadRandomFood { ///I make my array here then... int i = arc4random() % [RandomFood count]; myRandomSprite = (CCSprite *)[RandomFood objectAtIndex:i]; //waiterOnSCreen is a CCSprite added on the init [waiterOnSCreen addChild:myRandomSprite]; myRandomSprite.position=ccp(290,220); myRandomSprite.tag = RandomFoodTag; } } later in if(CGRectContainsPoint(waiterOnSCreen.boundingBox, location)) { //trying to remove the food here //Ive already tried to remove the sprite using [self removeChildByTag:RandomeObjectTag]; //and also CCSprite *wantedSprite = (CCSprite *)[self getChildByTag:RandomFoodTag]; [wantedSprite removeFromParentAndCleanup:YES]; } }

• Mysql dropping inserts with triggers

  - by user2891127

  Using mysql 5.5. I have two tables. One has a whitelist of hashes. When I insert a new row into the other table, I want to first compare the hash in the insert statement to the whitelist. If it's in the whitelist, I don't want to do the insert (less data to plow through later). The inserts are generated from another program and are text files with sql statements. I've been playing with triggers, and almost have it working: BEGIN IF (select count(md5hash) from whitelist where md5hash=new.md5hash) 0 THEN SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = 'Already Whitelisted'; END IF; END But there's a problem. The Signal throwing up the error stops the import. I want to skip that line, not stop the whole import. Some searching didn't find any way to silently skip the import. My next idea was to create a duplicate table definition, and redirect the insert to that dup table. But the old and new don't seem to apply to table names. Other then adding an ignore column to my table then doing a mass drop based on that column after the import, is there any way to achieve my goal?

• The best way to return related data in a SQL statement

  - by Darvis Lombardo

  I have a question on the best method to get back to a piece of data that is in a related table on the other side of a many-to-many relationship table. My first method uses joins to get back to the data, but because there are multiple matching rows in the relationship table, I had to use a TOP 1 to get a single row result. My second method uses a subquery to get the data but this just doesn't feel right. So, my question is, which is the preferred method, or is there a better method? The script needed to create the test tables, insert data, and run the two queries is below. Thanks for your advice! Darvis -------------------------------------------------------------------------------------------- -- Create Tables -------------------------------------------------------------------------------------------- DECLARE @TableA TABLE ( [A_ID] [int] IDENTITY(1,1) NOT NULL, [Description] [varchar](50) NULL) DECLARE @TableB TABLE ( [B_ID] [int] IDENTITY(1,1) NOT NULL, [A_ID] [int] NOT NULL, [Description] [varchar](50) NOT NULL) DECLARE @TableC TABLE ( [C_ID] [int] IDENTITY(1,1) NOT NULL, [Description] [varchar](50) NOT NULL) DECLARE @TableB_C TABLE ( [B_ID] [int] NOT NULL, [C_ID] [int] NOT NULL) -------------------------------------------------------------------------------------------- -- Insert Test Data -------------------------------------------------------------------------------------------- INSERT INTO @TableA VALUES('A-One') INSERT INTO @TableA VALUES('A-Two') INSERT INTO @TableA VALUES('A-Three') INSERT INTO @TableB (A_ID, Description) VALUES(1,'B-One') INSERT INTO @TableB (A_ID, Description) VALUES(1,'B-Two') INSERT INTO @TableB (A_ID, Description) VALUES(1,'B-Three') INSERT INTO @TableB (A_ID, Description) VALUES(2,'B-Four') INSERT INTO @TableB (A_ID, Description) VALUES(2,'B-Five') INSERT INTO @TableB (A_ID, Description) VALUES(3,'B-Six') INSERT INTO @TableC VALUES('C-One') INSERT INTO @TableC VALUES('C-Two') INSERT INTO @TableC VALUES('C-Three') INSERT INTO @TableB_C (B_ID, C_ID) VALUES(1, 1) INSERT INTO @TableB_C (B_ID, C_ID) VALUES(2, 1) INSERT INTO @TableB_C (B_ID, C_ID) VALUES(3, 1) -------------------------------------------------------------------------------------------- -- Get result - method 1 -------------------------------------------------------------------------------------------- SELECT TOP 1 C.*, A.Description FROM @TableC C JOIN @TableB_C BC ON BC.C_ID = C.C_ID JOIN @TableB B ON B.B_ID = BC.B_ID JOIN @TableA A ON B.A_ID = A.A_ID WHERE C.C_ID = 1 -------------------------------------------------------------------------------------------- -- Get result - method 2 -------------------------------------------------------------------------------------------- SELECT C.*, (SELECT A.Description FROM @TableA A WHERE EXISTS (SELECT * FROM @TableB_C BC JOIN @TableB B ON B.B_ID = BC.B_ID WHERE BC.C_ID = C.C_ID AND B.A_ID = A.A_ID)) FROM @TableC C WHERE C.C_ID = 1
