Thread: Get additional constraint information

Get additional constraint information

From
"Tobias Fielitz"
Date:
select * from information_schema.table_constraints where
table_name=‘install_crash’;

Results here: http://imgur.com/YymSvBS

How can I get more information about these constraints, especially on which columns the not null constraints are?

Thanks
