yuemeng updated FLINK-4827:
---------------------------
    Description: 
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 defined here,only tEnv defined here

  was:
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 defined here,it's tEnv defined here


> Sql on streaming example use scala with wrong variable name
