  • Delete document with an empty ID

    - by Damien MATHIEU
    Hello, I have a CouchDB database in production. One of the documents has been edited (in Futon by an other developer). And it's lost it's ID (don't ask me how he did it). So now the document's id is an empty string, which makes it impossible to edit or delete via Futon. Is there a way I could hack into CouchDB to delete that document anyway ?

    - by Matt
    I have a PHP application using an Oracle XE database. Whenever I add a date the hours minutes, and seconds seem to get left out. Is there some special format, or type I should use to be able to store this? I have tried using to_date, and specifying the format I am using.

  • Problem with modifying a page with ajax, and the browser keeping the unmodified page in cache.

    - by David Lawson
    Hey there, I have a situation where my page loads some information from a database, which is then modified through AJAX. I click a link to another page, then use the 'back' button to return to the original page. The changes to the page through AJAX I made before don't appear, because the browser has the unchanged page stored in the cache. Is there a way of fixing this without setting the page not to cache at all? Thanks :)

  • Android Google Analytics dispatch interval

    - by Bear
    In the document, it mentions that we can have a dispatch interval such that page view will be automatically dispatched after x seconds. I have the code like the following tracker.startNewSession("UA-YOUR-ACCOUNT-HERE", 20, this); I sure trackPageView() is called as I can see those pageview are stored into "google_analytics.db" which is the database that google analyitcs used to store non-dispatching pageview. However, it doesn't send to Google Analytics after 20 seconds In log, it keeps reporting scheduling next dispatch when I call trackPageView().

  • find all text before using regex

    - by jeff
    How can I use regex to find all text before the text "All text before this line will be included"? I have includes some sample text below for example This can include deleting, updating, or adding records to your database, which would then be reflex. All text before this line will be included You can make this a bit more sophisticated by encrypting the random number and then verifying that it is still a number when it is decrypted. Alternatively, you can pass a value and a key instead.

    Having understood some of the advantages that NoSQL offers (scalability, availability, etc.), I am still not clear why a website would want to use a non-relational database. Can I get some help on this, preferably with an example?

    - by user334017
    my basic database setup is: User:... Info: relations: User: { foreignType:one } When displaying information on the user it takes: 1 query to find info on the user, and 1 query to find additional info I want to reduce this to one query that finds both, I assume I need to override a function from BaseUser.class.php, or something along those lines but I'm not really sure what to do.

    - by Dave
    I've got a datagrid that is databound from a database table. How do I: a) Edit the displayed value for a column using the values from other columns in the row?

  • Populating a Combobox inside a Gridview

    - by Nawait
    i'm having a few problems working with a gridview and a combobox inside of it. Here is the code for my ListView control: <ListView Height="139" HorizontalAlignment="Left" Margin="10,158,0,0" Name="lvAppointment" VerticalAlignment="Top" Width="250" MinWidth="350"> <ListView.View> <GridView> <GridViewColumn Header="Appointment" Width="120"> <GridViewColumn.CellTemplate> <DataTemplate> <DatePicker SelectedDate="{Binding Path=Appointment}"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header="Type" Width="170"> <GridViewColumn.CellTemplate> <DataTemplate> <ComboBox ???/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header="Done" Width="50"> <GridViewColumn.CellTemplate> <DataTemplate> <CheckBox IsChecked="{Binding Path=Done}" IsThreeState="False"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> I'm popluating the list from a sql ce database via c# with the following code using (SqlCeCommand sqlCeAppointment = new SqlCeCommand("SELECT appid,appointment,done,apptype.type FROM appointment INNER JOIN apptype ON appointment.refatid = apptype.atid WHERE refeventid = @eventid;", sqlCeConn)) { sqlCeAppointment.Parameters.AddWithValue("@eventid", ((cListEventItem)lvEvent.SelectedItems[0]).id); using (SqlCeDataReader sqlCeAppointmentReader = sqlCeAppointment.ExecuteReader()) { lvAppointment.Items.Clear(); while (sqlCeAppointmentReader.Read()) { lvAppointment.Items.Add(new cListAppointmentItem { id = sqlCeAppointmentReader.GetGuid(sqlCeTerminReader.GetOrdinal("appid")), Appointment = sqlCeAppointmentReader.GetDateTime(sqlCeTerminReader.GetOrdinal("appointment")), Type = sqlCeAppointmentReader.GetString(sqlCeTerminReader.GetOrdinal("type")), Done = sqlCeAppointmentReader.GetByte(sqlCeTerminReader.GetOrdinal("done")) }); } } } I can popluate the list just fine. But i want "Type" to be a combobox so the user can select the apropriate type of the appointment (its a list of appointments connected to an event). This combobox should be filled with data thats inside a table of the sql ce database (apptype). This table is not static, the users can add and delete items from this list. I have tried a few ways i found via google, but failed. I guess i'm having problems understanding how this works/should work. I hope someone can help me :( Thanks in advance

  • Call Single StrConn from Multiple Pages

    - by Daniel
    I have a ocnnection to SQL Server set up in my vba code. The format is: strConn = "ODBC;Driver=SQL;Server=SQL1;Database=DB1;Uid=1;Pwd=1" I have this in 4 sheets, but there will be times when I will want to change it to call from SQL2 or SQL3, and instead of changing the code on each sheet 4 times, I want to change it only once. Is there a way to set up that line to run by calling it from somewhere else or by passing in a string into the ""?

  • pdo connection scope

    - by Scarface
    Hey guys I have a connection class I found for pdo. I am calling the connection method on the page that the file is included on. The problem is that within functions the $conn variable is not defined even though I stated the method was public (bare with me I am very new to OOP), and I was wondering if anyone had an elegant solution other then using global in every function. Any suggestions are greatly appreciated. CONNECTION class PDOConnectionFactory{ // receives the connection public $con = null; // swich database? public $dbType = "mysql"; // connection parameters // when it will not be necessary leaves blank only with the double quotations marks "" public $host = "localhost"; public $user = "user"; public $senha = "password"; public $db = "database"; // arrow the persistence of the connection public $persistent = false; // new PDOConnectionFactory( true ) <--- persistent connection // new PDOConnectionFactory() <--- no persistent connection public function PDOConnectionFactory( $persistent=false ){ // it verifies the persistence of the connection if( $persistent != false){ $this->persistent = true; } } public function getConnection(){ try{ // it carries through the connection $this->con = new PDO($this->dbType.":host=".$this->host.";dbname=".$this->db, $this->user, $this->senha, array( PDO::ATTR_PERSISTENT => $this->persistent ) ); // carried through successfully, it returns connected return $this->con; // in case that an error occurs, it returns the error; }catch ( PDOException $ex ){ echo "We are currently experiencing technical difficulties. We have a bunch of monkies working really hard to fix the problem. Check back soon: ".$ex->getMessage(); } } // close connection public function Close(){ if( $this->con != null ) $this->con = null; } } PAGE USED ON include("includes/connection.php"); $db = new PDOConnectionFactory(); $conn = $db->getConnection(); function test(){ try{ $sql = 'SELECT * FROM topic'; $stmt = $conn->prepare($sql); $result=$stmt->execute(); } catch(PDOException $e){ echo $e->getMessage(); } } test();
