我有下面的表格结构。

<h1>ID Country</h1>
1      Country1 <br/>
2      Country2 <br/>
3      Country3 <br/>
4      Country1 <br/>
5      Country2 <br/>
6      Country3 <br/>
7      Country1 <br/>
8      Country2 <br/>
9      Country3 <br/>
10      Country1 <br/>
11      Country2 <br/>
12      Country3 <br/>

我需要根据我传递给sql查询的国家的输出
如果我把country作为country1
然后我应该得到如下输出

1 Country1
4 Country1
2 Country2
5 Country2
7 Country1
10 Country1
3 Country3
6 Country3

总结2国家结果
提前谢谢。
