【问题描述】：

我有一个如下所示的餐桌产品：

我正在从产品表中获取数据，但我需要这些数据按价格从 LOW 到 HIGH。我试图通过升序获取产品价格，但我得到的升序为 1,2,3,4 现在我们的价格为 80,900,100,30，我需要这样的 30,80,100,900。我已经尝试过这个查询，但我没有得到确切的结果。

$low_to_high = DB::table('products')
                   ->where([
                            ['products_categories_id', $id]
                          ])->orderBy('price','ASC')->get();

结果数组：

【解决方案1】：

你可以通过像这样添加零来做到这一点

SELECT * FROM SampleData ORDER BY data_char+0;

您还可以更改数据库中的数据类型以获得准确的结果。

Varchar 到诠释

【解决方案2】：

您的价格字段很可能是一个类似字符串的类型，以便能够按数字（价格）排序，您应该将类型更改为数字字段，例如 Decimal。
如果我猜错了请告诉我
