[yezizp2012]

I hereby agree to the terms of the Singularity Data, Inc. Contributor License Agreement.

What's changed and what's your intention?

Correctly parse and format ExprQualifiedWildcard and FieldIdentifier from AST. Note that the prefix in ExprQualifiedWildcard could be None when handling (table.v1).*.

Details

dev=> create table t1 (s struct<v1 int, v2 VARCHAR>);
CREATE_TABLE
dev=> create view v1 as select (t1.s).v1, (t1).s.v2 from t1;
CREATE_VIEW
dev=> create view v2 as select (t1.s).* from t1;
CREATE_VIEW
dev=> create view v3 as select (t1).s.* from t1;
CREATE_VIEW
dev=> select * from v1;
 v1 | v2
----+----
(0 rows)

dev=> select * from v2;
 v1 | v2
----+----
(0 rows)

dev=> select * from v3;
