    [FLINK-4827][Docs] The scala example of SQL on Streaming Tables with wrong variable name…

    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
