Question

I have the following error message in my application:

My table looks like this:

public static final String ereignisid = "id";
public static final String TABLE_NAME_EREIGNIS="ereignis";
public static final String EREIGNISNAME = "ereignisname";
public static final String EREIGNISZEIT = "ereigniszeit";
public static final String EREIGNISGENAUERES = "ereignisgenaueres";
public static final String KINDID = "kindid";

private static final String TABLE_EREIGNIS_CREATE = "CREATE TABLE IF NOT EXISTS " + TABLE_NAME_EREIGNIS + " (" + ereignisid + " INTEGER PRIMARY KEY AUTOINCREMENT, "
        + EREIGNISNAME + " TEXT, " + EREIGNISZEIT + " TEXT, " + EREIGNISGENAUERES + " TEXT, " + KINDID + " INTEGER, FOREIGN KEY (" + KINDID + ") REFERENCES " + TABLE_NAME_Kind + "(" + id + "));";

This is the function where the error happens:

private ArrayList<Ereignis> datenfuerlistviewereignis(){
        DBHelper db = new DBHelper(this);
        ArrayList<Ereignis> arr = new ArrayList<Ereignis>();
        ListView lv = (ListView) findViewById(R.id.lvEreignisse);
        id = getIntent().getIntExtra("kinderid", 0);
        System.out.println("SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSss" + id);
        Cursor c = db.selectEreignis(id);
        c.moveToFirst();
        int count = c.getCount();
        int i = 0;

        while(c.moveToNext())
        { 


 // here happens the error!
                arr.add(new Ereignis(c.getString(c.getColumnIndex("ereigniszeit")), c.getString(c.getColumnIndex("ereignisname")) ));



            i++;
        }
        if(arr.size() > 0){
            return arr;
        }
        else{
            ArrayList<Ereignis> arrempty = new ArrayList<Ereignis>();
            arrempty.add(new Ereignis("Keine Daten vorhanden", " "));
            return arrempty;
        }
    }

Can someone tell me where my mistake is??

EDIT:

This is selectEreignis()

public Cursor selectEreignis(int kindid){
    SQLiteDatabase db = getReadableDatabase();
    Cursor cursor = db.rawQuery("SELECT ereignisname FROM EREIGNIS WHERE KINDID = " + kindid, null);

    System.out.println("HALLLIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII"  + cursor.getCount());
    return cursor;
}

Answer 1

Cursor cursor = db.rawQuery("SELECT ereignisname FROM EREIGNIS WHERE KINDID = " + kindid, null);

change it to

Cursor cursor = db.rawQuery("SELECT ereignisname, ereigniszeit  FROM EREIGNIS WHERE KINDID = " + kindid, null);

Do something like this if your table and query are fine.

    if(c.moveToFirst())
    {
    do
    {
    // your array stuff here
    }while(c.moveToNext());
    }

Answer 2

"ereigniszeit" isn't in the schema as a column name. Possibly a typo. Or possibly your selectEreignis function isn't asking for that column.

Answer 3

Please try to change the column name ereigniszeit or ereignisname and then try.Because this variable may be declared already in sqlite database schema

Answer 4

Ok, I added ereigniszeit in my selectEreignis() function.
