1. 你flink里声明的字段类型和数据库的类型不匹配，需要保持一致，数据库里是varchar，flink是timestamp，完整类型映射可以参考[1] 2. 你插入的两个字段（ocaltimestamp,current_timestamp）的值可以贴出来看看？ Best Leonard [1]https://ci.apache.org/projects/flink/flink-docs-master/zh/dev/table/connectors/jdbc.html#data-type-mapping <https://ci.apache.org/projects/flink/flink-docs-master/zh/dev/table/connectors/jdbc.html#data-type-mapping>
