flink1.9中blinkSQL对定义udf的TIMESTAMP类型报错

社区的各位大佬好:

使用场景:flink1.9版本使用flinkSQL创建udf函数使用没有问,当切换到blinkSQL使用这个udf就会报错TIMESTAMP类型错误,udf实现的功能也很简单,就是将时间+8小时,报错信息如下

    +8是想解决本身函数中的时区问题吧,可以直接用localtimestamp 这个没有时区问题。这样就不用自定义函数了

  • 你声明了DataType吗?代码怎么写的? 由于目前只支持精度<=3,所以你得用DataTypes.TIMESTAMP(3)来表示。*来自志愿者整理的flink邮件归档
