We are using data that is structured around the use of numerous tables.
However, in Mapinfo as opposed to other GIS, building new layers or
tables based on selections that are joined to other tables is laboured -
unless I am not doing something right.
Mapinfo won't allow selections on dynamic joins that are not "base
tables" (i.e the concept of a database view or table definition isn't
available).
The user has to make a copy of the selection (i.e. save copy as) then
build the next stage in the query to create a new table or layer.
This does not seem to me to be particularly efficient.
Does anyone have any ideas on building temporary or permanent tables on
the fly without adding to the existing data sets with an "intermediate"
layer, other than creating a "flat" table.
