------------------------------------
[~shawkins] I applied changes from the issue for 10.1.0 Teiid version. If I run such queries:
{code:sql}
select * from views.v x1 right join texttable(x1.a||'' columns a string) x2 on x1.a=x2.a ;;
select * from views.v x1 right join arraytable(array[x1.a] columns a string) x2 on x1.a=x2.a ;;
select * from views.v x1 right join OBJECTTABLE(language 'teiid_script' 'par1' PASSING x1.a AS par1 COLUMNS a string 'par1') x2 on x1.a=x2.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 ;;
--FULL JOIN
select * from views.v x1 full join texttable(x1.a||'' columns a string) x2 on x1.a=x2.a ;;
select * from views.v x1 full join arraytable(array[x1.a] columns a string) x2 on x1.a=x2.a ;;
select * from views.v x1 full join OBJECTTABLE(language 'javascript' 'par1' PASSING x1.a AS par1 COLUMNS a string 'par1') x2 on x1.a=x2.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 ;;
{code}
I get the same error as before:
{code:noformat}
Error: Remote org.teiid.api.exception.query.QueryResolverException: TEIID31119 Symbol x1.a is specified with an unknown group context
{code}

> All table functions cause errors in queries containing RIGHT or FULL JOINs. For example, such query:

> The behavior is expected. Lateral is expected to work left to right - thus only with inner/left joins. The error message should be improved. On pgsql it is "The combining JOIN type must be INNER or LEFT for a LATERAL reference".
