Major This case is similar to TEIID-2963. I can reproduce this in nightly build from master (0c7879a), which includes that fix.
Two selects from the same table in Oracle, and then a dummy select.
select "FOO"."SOURCE" "SOURCE", "FOO"."FOO_ID" "FOO_ID" from ( (select 'X' "SOURCE", "ITEMS"."ITEM_ID" "FOO_ID" from "BLAH"."ITEMS" "ITEMS" group by "ITEMS"."ITEM_ID") union all (select 'Y' "SOURCE", "ITEMS"."ITEM_ID" "FOO_ID" from "BLAH"."ITEMS" "ITEMS") union all (select 'Z' "SOURCE", '123' "FOO_ID") ) "FOO" order by "FOO_ID" desc limit 50;
Running that in Squirrel fails with this.
ORA-01789: query block has incorrect number of result columns
Formatted Oracle SQL from stacktrace below. Notice 'Y' is being selected in the second branch.
