What I would prefer is something like this:

CREATE TABLE foo(
  f1 int NOT NULL COMMENT
    'the first field',
  f2 int NOT NULL COMMENT
    'the second field',
...
);

which would ensure the comments are both next to the field definition they're documenting and that they make it all the way to the database. I looked into the biggest products, and MySQL supports this syntax.  I couldn't find any similar syntax in any other product.


​+1 for the idea - though restricting it to columns would not be ideal.


CREATE TABLE name 
COMMENT IS 
'Table Comment Here'
(
col1 serial COMMENT IS 'Place comment here'
)​;


And what about the other CREATE statements? IMHO if we follow this path then we should add COMMENT to all CREATE statements and perhaps also to ALTER. Of course in a set of small patches to make the reviewers life easier.
