Support of INCLUDING COMMENTS for Views

Up to version 6.1 Exasol does not copy column comments from views that are part of the like clause although the like clause contains INCLUDING COMMENTS.

Example:

CREATE SCHEMA a;
CREATE SCHEMA b;

CREATE TABLE a.t (i int COMMENT IS 'a number');
DESC FULL a.t; -- shows the column comment

CREATE TABLE b.t LIKE a.t INCLUDING COMMENTS;
DESC FULL b.t; -- shows the column comment

CREATE VIEW a.v(i COMMENT IS 'view-column comment') AS SELECT i FROM a.t ;
DESC FULL a.v; -- shows the view column comment

CREATE TABLE b.tv LIKE a.v INCLUDING COMMENTS;
DESC FULL b.tv; -- does not show the comment

Starting with version 6.2 Exasol also copies the column comments from views.
