推荐答案

这是一个想法。



1.首先，你笑了uld有一个名为Licenses的表，其中包含列（ CarId ， YearOfLicense ， Image ）。

2.选择年时，取值，然后在此处运行插入查询使用图像选择的 CarId 表格。

Here is the idea.

1. First of all, you should have a table named something like "Licenses" with Columns (CarId, YearOfLicense, Image).
2. When a Year is selected, you take the value and then run a insert query in this table against the CarId selected with the Image.
