Question

ı am making an application using sqlite which insert, update database. While ı’m insert and updating db. app throwed an CursorIndexOutOfBoundsException. ı know it is about cursor.Is there anyone who can help me?

public void EntryGiris(int yilsql, String aysql, int bakicisql,
        int krediArabasql, int krediOgrenimsql, int krediTatilsql,
        int faturaElektriksql, int faturaSusql, int faturaInternetsql,
        int aidatsql, int kaskoSigortasql) {

    ContentValues cv = new ContentValues();
    cv.put(C_YIL, yilsql);
    cv.put(C_AY, aysql);
    cv.put(C_BAKICI, bakicisql);
    cv.put(C_KREDIARABA, krediArabasql);
    cv.put(C_KREDIOGRENIM, krediOgrenimsql);
    cv.put(C_KREDITATIL, krediTatilsql);
    cv.put(C_FATURAELEKTRIK, faturaElektriksql);
    cv.put(C_FATURASU, faturaSusql);
    cv.put(C_FATURAINTERNET, faturaInternetsql);
    cv.put(C_AIDAT, aidatsql);
    cv.put(C_KASKOSIGORTA, kaskoSigortasql);

    String[] selectionArgs=new String[]{yilsql+"", aysql};
    String entryGirisSQL="SELECT c_id FROM harcamalar WHERE "+C_YIL+"= ? AND "+C_AY+"= ?";
    Cursor cursor=ourDatabase.rawQuery(entryGirisSQL, selectionArgs);
    cursor.moveToFirst();
    if(cursor.moveToLast()){
        int index=cursor.getInt(cursor.getColumnIndex(C_ID));
        if(index>=0)
            ourDatabase.update(DB_TABLE, cv, C_ID+"="+index, null);
        else ourDatabase.insert(DB_TABLE, null, cv);
    }

}

here is the exception:

Answer 1

if(cursor.getCount() > 0) {
cursor.moveToPosition(cursor.getCount() - 1);
    Long index=cursor.getLong(cursor.getColumnIndex(C_ID));
    if(index>=0)
            ourDatabase.update(DB_TABLE, cv, C_ID+"="+index, null);
    else ourDatabase.insert(DB_TABLE, null, cv);

}
