> Project: Ignite
> Issue Type: New Feature
> Components: sql
> Reporter: Yury Gerzhedovich
> Assignee: Vladimir Ermakov
> Priority: Critical
> Labels: calcite2-required, calcite3-required, ignite-3

> We should have ability to hide some columns. At first glance it's *_key*
> column. It really important for autogenerated PK.
> Such columns couldn't be accessed for 'select * ' query, but available for
> explicit use in select statement.
> Another example of hidden column is Oracle *rownum*.
> Also another databases (Oracle, SQLSERVER, MySQL) have support hidden
> (invisible) columns which could be created user explicitly and amend the
> visibility through ALTER statement. Maybe we should consider possible
> extension it for future to support one.
