Question

I have problem with sqlite database. I want create database in android with existing records.
I create database:

public class PrzyslowiaArabskie  {

private static final String TABLE_NAME = "tabela_przyslowia";
private static final String DATABASE_NAME = "przyslowiadb";
private static final int DATABASE_VERSION = 1;
public static final String KEY_ID = "id";
public static final String KEY_PRZYSLOWIE = "przyslowie";

private DbHelper myHelper;
private final Context myContext;
private SQLiteDatabase myDatabase;




private static class DbHelper extends SQLiteOpenHelper {

    public DbHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
        // TODO Auto-generated constructor stub
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        // TODO Auto-generated method stub
         db.execSQL("CREATE TABLE " + TABLE_NAME + " (" + 
                   KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
                 KEY_PRZYSLOWIE + " TEXT NOT NULL);" );


    } 

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // TODO Auto-generated method stub
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);

        onCreate(db);
    }

}
public PrzyslowiaArabskie(Context c) {
    myContext = c;
}
public PrzyslowiaArabskie open() {
    myHelper = new DbHelper(myContext);
    myDatabase = myHelper.getWritableDatabase();
    return this;
}
public void close() {
    myHelper.close();
}
public long createEntry(String przyslowie) {
    ContentValues cv = new ContentValues();
    cv.put(KEY_PRZYSLOWIE, przyslowie);
    return myDatabase.insert(TABLE_NAME, null, cv);

}
public String getData() {
    // TODO Auto-generated method stub
    String[] columns = new String[] { KEY_ID, KEY_PRZYSLOWIE };
    Cursor c = myDatabase.query(TABLE_NAME, columns, null, null, null, null, null);
    String result = "";

    int iRow = c.getColumnIndexOrThrow(KEY_ID);
    int iPrzyslowie = c.getColumnIndexOrThrow(KEY_PRZYSLOWIE);


    for(c.moveToFirst(); !c.isAfterLast(); c.moveToNext()) {
        result = result + c.getString(iRow) + " " + c.getString(iPrzyslowie) + "\n";
    }

    return result;
}

}

What can I do if I want that create database with existing records. How to add records together with create database?

Answer 1

You just need to insert values in the onCreate() method, after you’ve created the table:

@Override
public void onCreate(SQLiteDatabase db) {
  db.execSQL("CREATE TABLE " + TABLE_NAME + " ("
      + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
      + KEY_PRZYSLOWIE + " TEXT NOT NULL);" );

  ContentValues values = new ContentValues();
  values.put(KEY_PRZYSLOWIE , "My text");

  db.insert(TABLE_NAME, null, values);
  // ... etc...
} 

As a side note, if your database is more complicated than this simple example, you might want to delegate table creation and initialization to other methods or even classes.
