I can see the ALTER statements now. Which is why I asked.
I don't like the idea of including the trigger DDL, because that would
never execute in a clean environment.
(I've never used a tool that tried to do that when I've wanted the DDL)
I can go either way on index creation.

Does this imply SQL SYNTAX like:

SHOW CREATE TABLE <table_name>
[ INCLUDING { ALL | INDEXES | SEQUENCES | ??? }]
[EXCLUDING { PK | FK | COMMENTS | STORAGE | } ]
[FOR {V11 | V12 | V13 | V14 | V15 }] ??
?

The goal for me is to open the discussion, and then CONSTRAIN the focus.

Personally, the simple syntax:
SHOW CREATE TABLE table1;

Should give me a create table command with the table attributes and the
column attributes, FKs, PKs, Defaults. Etc.
But I would not expect it to generate index commands, etc.
