Description
In some cases, with the USING clause, the used column generates ambiguity exceptions with the AS operator.
OK : select r_regionkey from region r0 join region r1 using (r_regionkey)
OK : select r_regionkey * 2 as rk2 from region r0 join region r1 using (r_regionkey)
KO : select r_regionkey as rk from region r0 join region r1 using (r_regionkey)
The last query generates the following error:
org.apache.calcite.sql.validate.SqlValidatorException: Column 'r_regionkey' is ambiguous
