Question

I created a table using the SQLiteOpenHelper:

public void onCreate(SQLiteDatabase db) {
        // TODO Auto-generated method stub
        db.execSQL(
                "CREATE TABLE " + DATABASE_TABLE + " (" +
                KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
                KEY_NAME + " TEXT NOT NULL, " +
                KEY_SWIMMERLAPS + " INT NOT NULL, " +
                KEY_SPONSOR + " DEC NOT NULL );"

                );

How would I multiply the values of the swimmer laps by the sponsor using an SQLiteDatbase method?

Answer 1

Try this:

Cursor cursor = db.rawQuery("SELECT " + KEY_SWIMMERLAPS + " * " + KEY_SPONSOR + " AS result FROM " + DATABASE_TABLE, null);

if (cursor.moveToFirst()){
    Log.w("result", cursor.getDouble(0)+"");
}
