-------------------------------
    Steps to Reproduce: 
1. Configure in the test-vdb.xml the following virtual view and procedure:
{code:xml}
    <model visible = "true" type = "VIRTUAL" name = "views">
        <metadata type = "DDL"><![CDATA[
          create view v as select 1 a, 2 b;
          create virtual procedure pr(i integer) returns (a string)as
          begin
            select i||'';
          end 
        ]]>
        </metadata>
    </model>
{code}

2. Run the following queries for the first problem (TEIID30328 Unable to evaluate x1.a: No value was available):
{code:sql}
select * from views.v x1, table(select x1.a a) x2 join views.v x3 on x2.a=x3.a join views.v x4 on x4.a=x3.a ;;

select * from views.v x1, lateral(select x1.a a) x2 join views.v x3 on x2.a=x3.a join views.v x4 on x4.a=x3.a ;;

select * from views.v x1, xmltable('/a' PASSING xmlparse(document '<a id="' || x1.a || '"/>') COLUMNS a integer PATH '@id') x2 join views.v x3 on x2.a=x3.a join views.v x4 on x4.a=x3.a ;;
{code}

          end 
        ]]>

    </model>

{code:sql}
select * from views.v x1, table(select x1.a a) x2 join views.v x3 on x2.a=x3.a join views.v x4 on x4.a=x3.a ;;

{code}

3. Run the following queries for the second problem (TEIID31119 Symbol x1.b is specified with an unknown group context):
{code:sql}
select * from views.v x1 right join table(select x1.b a) x2 on x1.a=x2.a ;;

select * from views.v x1, table(select x1.a a) x2 right join views.v x3 on x2.a=x3.a ;;

select * from views.v x1 right join lateral(select x1.b a) x2 on x1.a=x2.a ;;

select * from views.v x1, lateral(select x1.a a) x2 right join views.v x3 on x2.a=x3.a ;;

select * from views.v x1 right join texttable(x1.a||'' columns a string) x2 on x1.a=x2.a ;;

select * from views.v x1, texttable(x1.a||'' columns a string) x2 right join views.v x3 on x2.a=x3.a ;;

select * from views.v x1 right join xmltable('/a' PASSING xmlparse(document '<a id="' || x1.a || '"/>') COLUMNS a integer PATH '@id') x2 on x1.a=x2.a ;;

select * from views.v x1, xmltable('/a' PASSING xmlparse(document '<a id="' || x1.a || '"/>') COLUMNS a integer PATH '@id') x2 right join views.v x3 on x2.a=x3.a ;;

-- FULL JOIN
select * from views.v x1 full join table(select x1.b a) x2 on x1.a=x2.a ;;

select * from views.v x1, table(select x1.a a) x2 full join views.v x3 on x2.a=x3.a ;;

select * from views.v x1 full join lateral(select x1.b a) x2 on x1.a=x2.a ;;

select * from views.v x1, lateral(select x1.a a) x2 full join views.v x3 on x2.a=x3.a ;;

select * from views.v x1 full join texttable(x1.a||'' columns a string) x2 on x1.a=x2.a ;;

select * from views.v x1, texttable(x1.a||'' columns a string) x2 full join views.v x3 on x2.a=x3.a ;;

select * from views.v x1 full join xmltable('/a' PASSING xmlparse(document '<a id="' || x1.a || '"/>') COLUMNS a integer PATH '@id') x2 on x1.a=x2.a ;;

select * from views.v x1, xmltable('/a' PASSING xmlparse(document '<a id="' || x1.a || '"/>') COLUMNS a integer PATH '@id') x2 full join views.v x3 on x2.a=x3.a ;;
