本文分析了Flink Table API中关于类型提示的错误，焦点在于遇到的'<KEYWORD> expected but was <LIST_SEPARATOR>'问题，原因在于输入中误用了逗号而非预期的关键字。解决方案简单，只需移除多余的逗号。

错误:

Caused by: org.apache.flink.table.api.ValidationException: Error in data type hint annotation.

Caused by: org.apache.flink.table.api.ValidationException: Could not parse type at position 11: <KEYWORD> expected but was <LIST_SEPARATOR>.

错误分析:

报错包在了类型提示上,所以去类型提示那一块找问题.

keyword 需要数据类型,但是你给了一个制表符

问题解决:

将逗号删除即可.
在这里插入图片描述

解决 Flink 中 Kafka 表定义主键约束的 ValidationException 错误

如果确实需要使用主键约束，可以将主键约束定义在下游的目标表中，例如关系型数据库表。-- 创建 Kafka 数据源表) WITH (-- 创建 PostgreSQL 目标表，定义主键) WITH (-- 执行插入操作在这个示例中，我们在 PostgreSQL 表中定义了主键station_id，而在 Kafka 表中不定义主键，这样可以避免错误。在使用 Flink 处理 Kafka 数据时，由于 Kafka 数据的特性和 JSON 格式的限制，不能直接在 Kafka 表中定义主键约束。
