be more specific; what tables -- html "< table > .. </ table >" or SQL tables? either of these do NOT have a MIME type so you've got me confused! Mime types are set in the HTTP header of a reply so the browser knows how to render the content --
To be more clear... When I use PhpMyAdmin to create SQL tables, there should be a MIME type field, but it is missing in my PhpMyAdmin.
That's odd, I've been using MySQL for quite a long time and I've never heard of mimetypes in tables. Then again, I prefer the command line to PHPMyAdmin.
The columns and types in database tables are arbitrary. Why do you think that there has to be a MIME type field? Or, if it has to be there, then just create it. That's what you are supposed to do when creating tables - define the fields and data types.
Haven't done this in some time -- however, one normally creates SQL tables as a background task, ie: command line or batch script, not online via a browser. ONLY the browser needs mimetypes. Even if using some online form the flow would still be fill in the form POST to a CGI script on the host run the sequence into MySQL verify no errors reply to the browser success/failure (needing a mimetype)
