Solved...sort of...

I changed the connection string with

DRIVER={MySQL ODBC 3.51 Driver}; SERVER=data.domain.com; PORT=3306; DATABASE=myDatabase; USER=myUsername; PASSWORD=myPassword; OPTION=3;

thanks to Zarko Gajic - http://delphi.about.com/od/mysql/qt/mysqladoconn.htm

OPTION = 3 seems to indicate

1 Don't Optimized Column Width The client can't handle that Connector/ODBC returns the real width of a column.
2 Return Matching Rows The client can't handle that MySQL returns the true value of affected rows. If this flag is set, MySQL returns “found rows” instead. You must have MySQL 3.21.14 or newer to get this to work.

http://dev.mysql.com/doc/refman/5.0/en/myodbc-configuration-connection-parameters.html

I guess this overrides the options in the ODBC administrator when using
pre-configured DSN.

But after that tere is still no change - the fields are padded with space.

Changing CHAR fields to VARCHAR solved the problem for me, but I'm still curious
is that a bug?

Let's mention my config again: Delphi 2006, MySQL 5.0.27 and MySQL Connector/ODBC 3.51.12.
