Maryann Xue commented on PHOENIX-3042:
--------------------------------------
Also, [~tdsilva], would it be possible to deal with the table alias the other
way around? Say, instead of not adding the alias, can we make
IndexExpressionParseNodeRewriter recognize the alias and be able to handle
index expressions with aliases? Not adding alias in rewriting could be
problematic for join queries, coz they can have same column names from
different table refs.
> Using functional index expression in where statement for join query fails.

> A simple scenario:
> {noformat}
> CREATE TABLE customer_phx ( c_customer_sk varchar primary key, c_first_name
> varchar, c_last_name varchar );
> UPSERT INTO customer_phx values ( '1', 'David', 'Smith');
> CREATE LOCAL INDEX CUSTINDEX ON customer_phx (c_customer_sk || c_first_name
> asc) include (c_customer_sk);
> select c.c_customer_sk from customer_phx c left outer join customer_phx c2
> on c.c_customer_sk = c2.c_customer_sk where c.c_customer_sk || c.c_first_name
> = '1David';
> {noformat}
> It fails with an Exception :
> {noformat}
