What is the recommended method to make changes to an existing GeoMedia Oracle feature class?
There are a number of software applications such as Oracle SQL Developer, TOAD, etc. that can be used to alter an existing GeoMedia feature class table. Change might include actions such as adding a column, deleting a column or changing a data type.
The following considerations should be taken into account so the table is properly displayed in GeoMedia after changes have been made.
To recognize changes to a table structure, the GeoMedia metadata will need to be deleted and re-inserted. Prior to deleting the metadata, it may be best to first review and note key aspects such as: Coordinate system assignment, primary key fields and geometry fields.
