Bowen Li updated FLINK-10487:
-----------------------------
Description:
On https://ci.apache.org/projects/flink/flink-docs-master/dev/table/sql.html ,
the example is :
{code:java}
StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();
StreamTableEnvironment tableEnv = TableEnvironment.getTableEnvironment(env);
// ingest a DataStream from an external source
DataStream<Tuple3<Long, String, Integer>> ds = env.addSource(...);
// SQL query with an inlined (unregistered) table
Table table = tableEnv.toTable(ds, "user, product, amount");
Table result = tableEnv.sqlQuery(
"SELECT SUM(amount) FROM " + table + " WHERE product LIKE '%Rubber%'");
// SQL query with a registered table
// register the DataStream as table "Orders"
tableEnv.registerDataStream("Orders", ds, "user, product, amount");
// run a SQL query on the Table and retrieve the result as a new Table
Table result2 = tableEnv.sqlQuery(
"SELECT product, amount FROM Orders WHERE product LIKE '%Rubber%'");
...
{code}
But there's no APIs like {{toTable()}} in StreamTableEnvironment
