• sIFR: dynamically inserting umlaut causes trouble

  - by arold

  Hi, let me state cleary at the beginning that I know about the embedding issue in flash. So, to the point. If sIFR replaces an umlaut (ä,ö,ü) which is hard coded in the HTML file everythings works fine. But when I want to insert it dynamically it is not displayed. I played around with charset options to specifiy the javascript file i'm referencing but it doesnt change a thing. Here's JavaScript and sIFR code: sIFR.replacements["#image-counter span"][0].replaceText("ö"); I tried as well to replace "ö" by "&ouml;" and "&#246" but this doesnt work around it either. Any ideas?

I used the solution below but I have errors in these 2 lines : creerFilm.setDate(5, new Date (getDateDebut().getDate())); creerFilm.setDate(6, new Date (getDateFin().getDate())); PreparedStatement creerFilm = connecteur.getConnexion().prepareStatement("INSERT INTO FILM (ID, REF, NOM, DISTRIBUTEUR, DATEDEBUT, DATEFIN) VALUES (?, ?, ?, ?, ?, ?)"); creerFilm.setInt(1, getId()); creerFilm.setString(2, getReference()); creerFilm.setString(3, getNomFilm()); creerFilm.setString(4, getDistributeur()); creerFilm.setDate(5, new Date (getDateDebut().getDate())); creerFilm.setDate(6, new Date (getDateFin().getDate())); creerFilm.executeUpdate(); creerFilm.close(); Can you help me to fix that please ?

• How do I guarantee row uniqueness in MySQL without the use of a UNIQUE constraint?

  - by MalcomTucker

  Hi I have some fairly simple requirements but I'm not sure how I implement them: I have multiple concurrent threads running the same query The query supplies a 'string' value - if it exists in the table, the query should return the id of the matching row, if not the query should insert the 'string' value and return the last inserted id The 'string' column is (and must be) a text column (it's bigger than varchar 255) so I cannot set it as unique - uniqueness must be enforced through the access mechanism The query needs to be in stored procedure format (which doesnt support table locks in MySQL) How can I guarantee that 'string' is unique? How can I prevent other threads writing to the table after another thread has read it and found no matching 'string' item? Thanks for any advice..

• Comparison tool with easy line insertion

  - by Miro Kropacek

  Back in good old days I used to use a tool for file comparison with one incredible feature -- you open file1, file2, see a difference, no magic here. But then you could insert an empty line(s) into file1 with one keyboard combo and into file2 with another keyboard combo. So you could easily adjust how are C / asm function aligned in case diff engine failed to recognize similar stuff. Of course, after the adjust (insertion / removal of one or more lines in either file) whole diff was "recalculated". I fail to find similar feature in diff, KDiff, ... I'd prefer Linux app but I'm OK with Windows app as last resort... Thanks for any hint!

• How can I get values from one table to another via similar values?

  - by Andrija

  I have a table called excel that has 3 columns, name, id, and full_name. The name part is the only one I have and I need to fill id and full_name. The other table that contains the data is called tim_pismena and has 2 columns that I need, id and pismeno_name (the actual names are not important, but i'm writing them just for clarity). In pseudooracle code :) the select that gets me the values from the second table would be done something like this: SELECT tp.id, tp.pismeno_name FROM tim_pismena tp WHERE upper(tp.naziv_pismena) LIKE IN upper('%(SELECT ime as FROM excel)%') and when used with an insert, the end result should be something like name id full_name Happy Joe 55 Very fun place Happy Joe, isn't it?

• I can't delete record in Codeigniter

  - by jomblo

  I'm learning CRUD in codeigniter. I have table name "posting" and the coloumns are like this (id, title, post). I successed to create a new post (both insert into database and display in the view). But I have problem when I delete my post in the front-end. Here is my code: Model Class Post_Model extends CI_Model{ function index(){ //Here is my homepage code } function delete_post($id) { $this->db->where('id', $id); $this->db->delete('posting'); } } Controller Class Post extends CI_Controller{ function delete() { $this->load->model('Post_Model'); $this->Post_Model->delete_post("id"); redirect('Post/index/', 'refresh'); } } After click "delete" in the homepage, there was nothing happens. While I'm looking into my database, my records still available. Note: (1) to delete record, I'm following the codeigniter manual / user guide, (2) I found a message error (Undefined variable: id) after hiting the "delete" button in the front-end Any help or suggestion, please

• Android - Access to online Database SQlite

  - by Oneiros

  I need to open, read and insert items into an online SQLite database from an Android app. I know url, username and password. In JavaSE i would do the following: Class.forName("com.mysql.jdbc.Driver"); Connection dbConnection = DriverManager.getConnection(URL, USER, PASSWORD); I read that I can't do this in Android because there is not a JDBC Driver (there is a "SQLite.JDBCDriver" but it is not documented and not recommended). So which is the easiest way? I asked to Google but it looks like he either doesn't know.

• Why in the hell is this happening?

  - by user202411

  I just can't understand why is my database (mysql) behaving like this! My console shows that the record is created properly (please, notice the "remote_id" value): Tweet Create (0.3ms) INSERT INTO `tweets` (`remote_id`, `text`, `user_id`, `twitter_account_id`) VALUES (12325438258, 'jamaica', 1, 1) But when I check the record, it shows that the remote_id is 2147483647 intead of the provided value (12325438258 in the example above)... This table has many entries, but this field is always written with 2147483647... It was supposed to fill this space with an unique id (which I guarantee you is being generated properly).

• if specific row = null, execute query

  - by fusion

  how do i check if the value of a column is null, and only then execute the query? for example: col1 col2 col3 01 abc i run a query which first checks if the record exists or not; if it exists, it should execute the update query and if it doesn't exist, it executes the insert query. how do i check if col3 is null and if it is null, it should execute the update query. . $sql = "SELECT uid FROM `users` WHERE uid = '" . $user_id . "'"; $result = mysql_query($sql,$conn) or die('Error:' .mysql_error()); $totalrows = mysql_num_rows($result); if($totalrows < 1) { insertUser($user_id,$sk, $conn); } else { updateSessionKey($user_id,$sk,$conn); }

• Android sql creating database once

  - by semajhan

  One thing i'm not understanding is how to create the database and data just once in an android application. I extend SQLiteOpenHelper and use a DataHelper class that to manipulate data. Now, I have addEvent() and updateEvent() within the DataHelper class. I create an instance of DataHelper in my Activity and addEvent() a couple of times to insert data. Well, now I don't know how to just do that once. If I restart the app, its just going to "addEvent()" again and so the data is being reset every time. Sorry for the probably really REALLY noob question. The only solution I found was not using the DataHelper class and just adding data "manually" within the onCreate() method in SQLiteOpenHelper.

• Mysql: how do I make an exact working copy of a table?

  - by epo

  I am working on a restructuring of a legacy database and its associated applications. To keep old and new working in parallel I have created a development database and copied the tables of interest to it, e.g. create database devdb; drop table if exists devdb.tab1; CREATE TABLE devdb.tab1 like working.tab1; insert into devdb.tab1 select * from working.tab1; Having done this I notice that triggers affecting tab1 have not been copied over. Is there any way in which I can produce a working copy of tab1, i.e. data, permissions, triggers, everything?

• Inserting text into a textarea using .load() in jQuery

  - by bateman_ap

  Hi, having a bit of a nightmare, I am trying to use jQuery to insert some text taken from a .load() call into a form field (textfield) after a user logs in (basically prefilling some known details) The code I am using is: $.ajax({ type: "POST", url: "/ajax/login.php", data: dataString, success: function(html) { if (html == 1) { $("#loginPanel").load("/ajax/login-panel.php"); $("#bookName").load("/ajax/getSessionDetails.php #userUsername"); $("#bookEmail").load("/ajax/getSessionDetails.php #userEmail"); $("#bookingLogin").hide("fast"); } else { $("#loginError").html("Sorry, login failed, please try again"); } } }); If I hardcode such as $("#bookName").html("Test Content"); it works OK so it must be a problem with the .load call. I looked around and found some guy suggest something like the following code but I couldn't get it to work: $.get(htmlBannerUrl, function(data){ $('textarea').val(data); });

• Highly efficient filesystem APIs for certain kinds of operations

  - by romkyns

  I occasionally find myself needing certain filesystem APIs which could be implemented very efficiently if supported by the filesystem, but I've never heard of them. For example: Truncate file from the beginning, on an allocation unit boundary Split file into two on an allocation unit boundary Insert or remove a chunk from the middle of the file, again, on an allocation unit boundary The only way that I know of to do things like these is to rewrite the data into a new file. This has the benefit that the allocation unit is no longer relevant, but is extremely slow in comparison to some low-level filesystem magic. I understand that the alignment requirements mean that the methods aren't always applicable, but I think they can still be useful. For example, a file archiver may be able to trim down the archive very efficiently after the user deletes a file from the archive, even if that leaves a small amount of garbage either side for alignment reasons. Is it really the case that such APIs don't exist, or am I simply not aware of them? I am mostly interested in NTFS, but hearing about other filesystems will be interesting too.

• Are Triggers Based On Queries Atomic?

  I have a table that has a Sequence number. This sequence number will change and referencing the auto number will not work. I fear that the values of the trigger will collide. If two transactions read at the same time. I have ran simulated tests on 3 connections @ ~1 million records each and no collisions.

• Entity framework Update fails when object is linked to a missing child

  - by McKay

  I’m having trouble updating an objects child when the object has a reference to a nonexising child record. eg. Tables Car and CarColor have a relationship. Car.CarColorId CarColor.CarColorId If I load the car with its color record like so this var result = from x in database.Car.Include("CarColor") where x.CarId = 5 select x; I'll get back the Car object and it’s Color object. Now suppose that some time ago a CarColor had been deleted but the Car record in question still contains the CarColorId value. So when I run the query the Color object is null because the CarColor record didn’t exist. My problem here is that when I attach another Color object that does exist I get a Store update, insert error when saving. Car.Color = newColor Database.SaveChanges(); It’s like the context is trying to delete the nonexisting color. How can I get around this?
