再次感谢,成功了,这个问题困扰我两周了。还有个问题,能麻烦帮我看下嘛

如上,这里定义的 ts_watermark, 想用他们做 watermakr,但是他的返回结果是 null, 我的 maxwell_ts 是
millseconds,我看了函数的使用方法,没想到哪里有问题

val bsSettings =
EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build()
val bsTableEnv = StreamTableEnvironment.create(env, bsSettings) val
sourceTable = """CREATE TABLE my_kafak_source ( | `table` varchar, |
`database` varchar, | `data` row < transaction_id varchar, | user_id int, |
amount int, | >, | maxwell_ts bigint, | ts_watermark as
TO_TIMESTAMP(FROM_UNIXTIME(maxwell_ts/1000)) |) WITH ( |)""".stripMargin
