> h2. *在使用flink1.10sql发现decimal精度溢出返回null的问题*
> 这是我的代码
> !image-2020-12-03-21-47-31-755.png|width=835,height=435!
> !image-2020-12-03-21-48-44-901.png!
> 计算结果为null
> {color:#de350b}定位源码发现{color}
> {color:#de350b}codegen的代码中调用了{color}
> !image-2020-12-03-21-49-40-529.png!
> {color:#de350b}其中这个方法{color}
> !image-2020-12-03-21-50-11-117.png!
> 会出现得到一个39位的溢出就会直接返回null，导致计算结果错误为null
> 我的思路是在此截断精度，或者能提供精度的配置入口
> 可以考虑指派给我修复这个问题
