Thomas D'Silva commented on PHOENIX-3042:
-----------------------------------------
I didn't modify how aliases are handled in the join code. I modified
IndexExpressionParseNodeRewriter to set the setTableAlias boolean to true while
creating IndexStatementRewriter. When we build the map of function expression
parse node to the corresponding index column parse node it includes the table
alias.
> 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}
> Error: ERROR 504 (42703): Undefined column. columnName=C_FIRST_NAME
