dalex dalex updated TEIID-5271:
-------------------------------
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}
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 ;;
