Invisible Columns

[dveeden]

Support things like this:

CREATE TABLE t1(
  id int PRIMARY KEY,
  c1 int INVISIBLE
);

This is useful for:

• A part of Generated Invisible Primary Keys (GIPK) ( https://dev.mysql.com/doc/refman/8.4/en/create-table-gipks.html )
• Indexes on generated columns that are hidden. To have functional indexes with breaking INSERT and SELECT where the column list isn't supplied.
