Can POLYGON and FLAT tables be joined?
Yes! Before Techbase Version 2.40, the FLAT – POLYGON table join structure did not permit color coding (when using POSTER etc.) of the polyline by reading fields in the joined flat table. In the past, in order to have graphics style by field all attribute fields needed to be in the polygon table. This was changed in version 2.4 by the addition of JOIN-inheritance. Remember that in a JOIN, you join tables in the order “many” to “few”. A JOIN table inherits the table type of Table 1 (the “many”) in the join.
