问题描述
我有一个表包含以下列
Id，imagename，countRate
有很多表中包含不同imagesname的行。
所有图像显示在前端，点击按钮后每个图像增加该图像的countRate。我的困难是，我怎么知道任何perticulare countRate是受尊重的imageName。在where where子句中我应该提到什么，因为Id不为我所知。

I have one table contain following columns
Id,imagename,countRate
there are many rows in table containing different imagesname.
those all images are shown into the front end, after clicking on button with each image increment the countRate of that image. My difficulty is that how can I know that any perticulare countRate is for respected imageName. in where clause what should i have to mention as Id is not known to me.
