The scala example of SQL on Streaming Tables with wrong variable name in
flink document
val env = StreamExecutionEnvironment.getExecutionEnvironment
val tEnv = TableEnvironment.getTableEnvironment(env)
// read a DataStream from an external source
val ds: DataStream[(Long, String, Integer)] = env.addSource(...)
// register the DataStream under the name "Orders"
tableEnv.registerDataStream("Orders", ds, 'user, 'product, 'amount)
// run a SQL query on the Table and retrieve the result as a new Table
val result = tableEnv.sql(
"SELECT product, amount FROM Orders WHERE product LIKE '%Rubber%'")
There is no variable named tableEnv had defined ,Only tEnv defined here
