我的编码

  public void addToCart (Order order)
    {
        SQLiteDatabase db = getReadableDatabase();
        String query = String.format("INSERT FROM OrderDetail(ProductId,ProductName,Quantity,Price,Discount)VALUES('%s','%s','%s','%s','%s');",
                order.getProductId(),
                order.getProductName(),
                order.getQuantity(),
                order.getPrice(),
                order.getDiscount());
        db.execSQL(query);

    }

Answer 1

问题在于SQL查询。它就像

INSERT INTO TABLE_NAME [(column1, column2, column3,...columnN)]  
VALUES (value1, value2, value3,...valueN);

所以你的情况

String query = String.format("INSERT INTO OrderDetail(ProductId,ProductName,Quantity,Price,Discount)VALUES('%s','%s','%s','%s','%s');", order.getProductId(), order.getProductName(), order.getQuantity(), order.getPrice(), order.getDiscount()); db.execSQL(query);

希望这会有所帮助。

Answer 2

您的query错了

使用 INSERT INTO 代替 INSERT FROM

试试这个

public void addToCart (Order order)
    {
        SQLiteDatabase db = getReadableDatabase();
        String query = String.format("INSERT INTO  OrderDetail(ProductId,ProductName,Quantity,Price,Discount)VALUES('%s','%s','%s','%s','%s');",
                order.getProductId(),
                order.getProductName(),
                order.getQuantity(),
                order.getPrice(),
                order.getDiscount());
        db.execSQL(query);

    }
