Yijie Shen updated FLINK-3926:
------------------------------
Comment: was deleted
(was: Yes, I know the convention of `f` followed by index, but it's a public
API so it's arguments will be of any style :)
I find this while I was doing table exception clean up, we have this code for
field look up:
{{{
case t: TupleTypeInfo[A] =>
exprs.zipWithIndex.map {
case (UnresolvedFieldReference(name), idx) => (idx, name)
case (Alias(UnresolvedFieldReference(origName), name), _) =>
val idx = t.getFieldIndex(origName)
if (idx < 0) {
throw new TableException(s"$origName is not a field of type $t")
}
(idx, name)
case _ => throw new TableException(
"Field reference expression or alias on field expression expected.")
}
}}})
> Incorrect implementation of getFieldIndex in TupleTypeInfo
