Creating a spatial column (Sybase Central)

You can add spatial data to any table by adding a column that supports spatial data.

Prerequisites

You must be the owner of the table, or have ALTER privilege on the table, or have the ALTER ANY TABLE or ALTER ANY OBJECT system privilege.

The table must have a primary key. Update and delete operations are not supported for tables that contain a spatial column unless a primary key is defined.
