Yijie Shen commented on FLINK-3926:
-----------------------------------
We have the test case:
{code}
public void testAsWithNonFieldReference2() throws Exception {
ExecutionEnvironment env =
ExecutionEnvironment.getExecutionEnvironment();
BatchTableEnvironment tableEnv =
TableEnvironment.getTableEnvironment(env, config());
// Must fail. as() does only allow field name expressions
tableEnv.fromDataSet(CollectionDataSets.get3TupleDataSet(env),
"a as foo, b, c");
}
{code}
a is not a field in tupleDataSet, but we need to look it up from TupleTypeInfo.
> Incorrect implementation of getFieldIndex in TupleTypeInfo
