Mysql table rows show as questionmarks

Hi guys,
I'm trying to display the rows of my database table in a datagrid, but as their names are written in bulgarian they appear as questionmarks. Any tips on how I can fix this?
Thanks in advance

I figured it out myself... Just wanted to post the solution if anybody has the same
problem. I had a php script that I used to populate a data grid. Here is the code with the line I had to add to make the table names appear normally:
<?PHP
class PlayersService {
public function getPlayers()
  $connection = mysqli_connect("host", "username", "password", "db") or die(mysqli_connect_error());
  mysqli_query($connection, "SET CHARACTER SET utf8");
  $sql = "SELECT * FROM players";
  $result = mysqli_query($connection, $sql) or die("Query failed: " . mysqli_error($connection));
  $rows = array();
  while ($row = mysqli_fetch_object($result))
   $rows[] = $row ;
  return $rows;
?>

  • Best way to select several mysql table rows at random?

    What is the best and quickest way to have one form button select multiple rows from a table with complete randomness?
    Can you also offer some explanation (or link to a good tutorial)- I am a beginner in myql and php.
    thanks
    p.s. the id column in my table is auto incrementing and has some gaps (due to deletions of records). I do not want any of those gaps to be chosen at random (can they?).

    What do you have so far? How many rows will your table have and how many do you want to randomize? To produce random result without filter will put a strain on your server, especially if you have a lot of rows and you get a lot of server requests (pageloads). To randomize the results you basically have to recreate the table dynamically then output the result as an array. Again, this will put a huge load on your server. This may sound silly and ridiculously obvious, but have you tried searching the obvious term on google for MySQL random? There are millions of articles that describe the subject. Many first page results will show you exactly what you need to do. Try searching first then if you have trouble ask here, referencing the article you followed by first searching google.

  • Simple mysql table row update

    Hi all,
    I am new to flex. Literally days into this. I have followed an example from the flex 3 bible and created a Flex applciation calling an AMFPHP service. I got the hello world to appear and was pretty chuffed with that. (code used is below)
    I have been asked to use some php code that I used to successfully add a row to my database. Apparently this is easy but I'm not getting it.
    All I want to do in this instance is add one row of data to my table. I guess I would just insert my php code in as a statement somewhere right?
    The table is on a server
    <?xml version="1.0" encoding="utf-8"?>
    <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
        <mx:RemoteObject id="phpService"
        destination="amfphp"
        source="MyClass. HelloWorld"/>
        <mx:Button label="Say Hello" click="phpService.sayHello()"/>
        <mx:Label text="{phpService.sayHello.lastResult}"/>
    </mx:Application>
    Below: Is this the right bit of code that would update?
    var sql:String =
        "INSERT INTO mytable (Row1, Row2, Row3 , Row4, Row5, Row6, Row7, Row8, Row9 , Row10) " +
        "VALUES ('Data1', 'Data2',  'Data3', 'Data4', 'Data5', 'Data6', 'Data7', 'Data8', 'Data9', 'Data10')";
    insertStmt.text  = sql;
    I really am confused by all this.
    Thanks in advance for any help

    Hi,
    here is a bit of code that may help you, when using amfphp you would have the php class that updates the record, to call that class from flex you would declare it as a remote object. You then send that object with the data to the server where the sql updates the table. The code below is for inserting a record updating a record requires a slightly different sql statement but the principle is pretty much the same.
    If you are using flashbuilder you can use zendamf and the data wizard will create your actionscriptcode and your php services code.

  • Exporting a MySQL table to Excel

    My users have asked for the ability to download a MySQL table to an Excel spreadsheet. Being an amateur at all this PHP stuff I googled around and found a script that is supposed to do this. It's failing with "Couldn't select database: Access denied for user 'holli10_tonybabb'@'%' to database '_admin' 1044"
    It seems to be picking up an extra "@%" from somewhere

  • Only first row of a mysql table is updated

    Hi,
    I'm using Netbeans 5.5 with Visual Web Pack and trying to update data, stored in a mysql table.
    I use a dropdown list to select a row and show the data in various textfields. This works fine. The problem, that it's not possible to save changes, I enter in the textfields. Everytime only the first row of the table will be (over)written. This happens also with the derby database. I checked the tutorial about inserting, updatting and deleting, it works fine. But they use a table to make changes to the data, so the case is different from mine.
    Can anybody give me a hint? I'm going crazy ...
    Thanx in advance
    Markus

    yes this sounds crazy. i encountered similar problem with textfields. if they are numerous type, don't forget to add integerConverter to the textfield. it helped me out in my case. hope this helps

  • How to show asterisk for required fields in a table row?

    Hi Folks,
    For showing the asterisk (*) for required fields in a form, I used to give required="true" for the component and surround the component with a af:panelLabelAndMessage for which I set showRequired="true". How to do this for a component in a table row. For a component in a table, there is no label per se. The required=true flag in the component shows proper error message saying that it is required but there is no (*) for that component.
    Thanks
    Vishal

    Table does not have any required attribute.But column has showRequired property .You can used this.If column has input text then also you put required true on this component.And set your required messages there .
    It will resolve your problem
    Thanks

  • Only one row show in table with tablepopin

    Hi,
    I've a table with a tablecolum with a tablepopintogglecell, and a tablepopin.
    I want that only one row show (when i press the togglelink if there is other row open, automatically close that row)

    Hi,
    you should implement the on toggle event,
    you will have the importing context_element, so you know which one is triggered,
    form your node, get_elements().
    loop over the table where ne to context_element, clear the popin attribute,

  • Table Rows with Multiple Conditions Not Showing Up in RH

    Hi everyone,
    I'm currently evaluating TCS2 (Framemaker 9 and RoboHelp 8 on Windows XP) and have come across the following issue:
    One of our FrameMaker source files contains a table in which one of the rows has multiple conditions applied. When one of the conditions is shown in Framemaker, and the others are hidden, the row is displayed in Framemaker as expected. However, when the file is then imported or linked into Robohelp, the same table row vanishes, even though the Apply FrameMaker Conditional Text Build Expression check box is selected in the Framemaker Conversion Settings > Other Settings screen. This only appears to affect table rows - when paragraph text is tagged with the same conditions, it is imported correctly into RoboHelp.
    For example, when Condition B is shown and Condition A is hidden in the Framemaker file, the content appears like this in Frame:
    Unconditional
    Unconditional
    Condition A and Condition B applied
    Condition A and Condition B applied
    Condition B applied
    Condition B applied
    Paragraph text with Condition A and Condition B applied.
    Paragraph text with Condition B applied.
    When the same file is imported into RoboHelp, the row with both conditions applied is absent from the table:
    Unconditional
    Unconditional
    Condition B applied
    Condition B applied
    Paragraph text with Condition A and Condition B applied.
    Paragraph text with Condition B applied.
    Installing patches 8.0.1 and 8.0.2 did not resolve the issue (and actually caused other, unrelated issues) and I see the same behavior regardless of whether I import or link the FrameMaker document.
    Has anyone else seen this issue? Any help would be much appreciated.
    Thanks
    DaveB

    It just seems that the items I select as align to top in the
    property inspector should force the items to the top of their
    cells, unless I'm missing something.

  • Opening a new view in a new window on click of a table row entry.

    Hi Guys,
    How to open a new View of a same application in a new window (just like a pop up) on a click of a Table Row entry?
    I am using NWDS 7.0 version. So please suggest acccorrdingly.

    Hi Nikesh,
    first of all you will have to declare use of onLeadSelect event handler for your table (note that it will only be triggered when a lead selection occurs not a multiselection).
    Also, you can build at design time a View and a Window (for example, PopupWin) in your WebDynpro Component, and embed the view into the window.
    In your code for onLeadSelect function, you can use something like this to pop up the window.
    public void onActionRowSelection(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
        //@@begin onActionSeleccionTabla(ServerEvent)
        IWDWindowManager windowManager = wdComponentAPI.getWindowManager();
        IWDWindowInfo windowInfo = wdComponentAPI.getComponentInfo().findInWindows("PopupWin");
        IWDWindow window = windowManager.createModalWindow(windowInfo);
        window.setWindowPosition(WDWindowPos.CENTER);
        window.setWindowSize(new WDCssSize(450, WDWindowUnitOfLength.PX) , WDCssSize.UNDEFINED);
        // Store handle ti window in context attribute to able to close it later
        wdContext.currentContextElement().setPopup(window);
        window.show();
        //@@end
    Hope it helps,

  • How can i access a mysql table without putting the data in a datagrid

    I developed my air app with a datagrid which uses a php service to display all data from a table of strings in MySql.
    I now do not need the datagrid, how can i get the data from my database without putting it into a dataGrid? Do i need an array? how do i do this? anyone got any example code?

    var resultArrayCollection:ArrayCollection=new ArrayCollection()
    protected function resultHandler(event:ResultEvent)
         result=event.result as ArrayCollection
    You can use the result array collection now inside your program for any further changes / manipulations.
    Hope this helps; If you have further doubts, do ask...

    Hi, yeah this helps,
    however, how would i generate a result handler for a service that has not been called yet? Sorry my knowledge of services is very limited.
    This is a php service, get_all service that returns all the rows from a mysql table.
    I can see the service box with the service i want to use:
    but how do i pass that to a result handler?

  • Problem in inserting data into MySQL table

    Hi All,
    I have a table with just two fields FIRSTNAME and SECONDNAME in MySQL. I am accepting the First Name and Second Name in two text fields and then trying to insert them into the MySQL table. I have set the concurrency of the rowset to CONCUR_UPDATABLE and am using the code clip for Database row insert with the appropriate changes. When I run the application it doesnt give me any errors but the data is also not inserted in the table. Can someone pls help me out.
    Loneliness wins the race :-)

    This is my problem when inserting single row. What does it means ?
    MusicInsert: com.mysql.jdbc.NotUpdatable: Result Set not updatable.This result set must come from a statement that was created with a result set type of ResultSet.CONCUR_UPDATABLE, the query must select only one table, and must select all primary keys from that table. See the JDBC 2.1 API Specification, section 5.6 for more details

  • Fields missing from MYSQL table in Database Expert

    I have just updgraded from Crystal XI to 2011 and I am still having issues with joining a mysql table to any other table.
    Fields show up in field explorer but when I try to uise Database expert the only filed in the MYSQL table is the ID field.
    Am I missing something here. Same problem with both versions. When I runa report using just the mysql table evrything works fine.

    Typically if the field doesn't show up the CR can't figure out what type it is which means when we query the DB for the field type the client/server returns the wrong type or some type that CR doesn't support.
    How is the field defined on the server?
    Thank you

  • DW CS3 Unexpected table row growth.

    upgraded to CS3 from DW8, DWMX and found the following
    problem with my pages.
    I should say with the way they display in DW CS3.
    The problem is that the row expands in design view to
    accommodate the variable names, unlike previous prevouse versions
    that display the table at its true size.
    In this example:
    <td colspan="2" class="smallbutton"><div
    align="left">
    <%=(KT_escapeAttribute(rsPub_Participant.Fields.Item("sFName").Value))%> 
    <%=(KT_escapeAttribute(rsPub_Participant.Fields.Item("sMName").Value))%> 
    <%=(KT_escapeAttribute(rsPub_Participant.Fields.Item("sLName").Value))%></div>
    </td>
    Under older versions the table row will not grow to
    accommodate each of the fields. But in DW CS3 it does making it
    difficult to design a page.
    Question: How can I turn this off "fix it"?
    Thanks
    Mark this message as the answer.

    In Preferences > Invisible Elements, set "Show dynamic
    text as" to "{}"
