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
