Danny Chan updated CALCITE-3201:
--------------------------------
Description:
Now if we have a target table with schema:
{code:sql}
t1
: - a int not null
- b bigint STORED
- c varchar VIRTUAL
{code}
and validate a query like:
{code:sql}
insert into t1 select a from t1;
{code}
It would throw exception because the target table fields count is 3 but the
query is 1,
actually the table t1 columns b and c have strategy that we can not insert
into, so we better
ignore these columns when do validation.
The following query in SQLSERVER-2017 passed:
{code:sql}
create table t(
a int,
b int,
c as a+2
);
-- insert into t values(1, 2, 3) fails with non-equal schema fields count.
insert into t values(1, 2);
{code}
