Detailed Description

Column type description for foreign key columns compatibility check.

Contains subset of information from dd::Column class. It is inconvenient to use dd::Column class directly for such checks because it requires valid dd::Table object and in some cases we want to produce Ha_fk_column_type right from column description in Create_field format.
