Not able to generate column descriptions in DDL script
説明
If there are comments on an entity's attribute, they are not included in the DDL script that is generated.
対策
To generate the table’s column comments, the schema/owner has to be defined. To define a schema/owner for the entity, go to the General tab, in the Entity Properties window, and select a schema from the Schema box or click the icon on the right to open the Schema dialog and define a new schema, then select it for the entity.
