Julian,
Thanks for the quick response.
Sorry but I don't seem to see how I make the column optional. I am
looking at RelDataType and don't see anything that springs out at me.
Am I way off the mark?
thanks

I think if you make the column optional the validator will let you omit it from
the INSERT. (It’s not really optional, but it has a default value, which is
similar.)
And you’ll need to provide a different value for
SqlToRelConverter.defaultValueFactory so that the column gets populated with the
correct expression. See the changes I made to SqlToRelConverter to fix

Hi,
I am trying to add a system column to my table, lets call it rowid for argument
sake and familiarity.
I want to be able to do inserts without specifying rowid as it is added only on
the way out as a system column
So if I do this
Add a column called rowid to the metadata about table test
then do:
INSERT INTO test VALUES(7, 42, 101, 1001, 't', 1.1, 2.2, 'foo', 'real_foo',
'2014-12-13 22:23:15', '15:13:14', '1999-09-09', 9, 111.1);
I get this
org.apache.calcite.sql.validate.SqlValidatorException: Number of INSERT target
columns (15) does not equal number of source items (14)
As it knows I don't have enough columns as I have added rowid to my metadata
about the table.
If I don't add the rowid to the metadata I fail when attempting to do a select
from the table which includes rowid in the projection.
ie: Select value1, rowid from test;
So I am wondering what is the recommended way to deal with system columns in
this kind of circumstance.
thanks
