Product Feature: Queries and Selections
Unfortunately a left- or right join is not possible in MapInfo Pro. But there is a workaround which might help to visualize matching features:
- Add a column to the geometry table (all data sets).
- Join the tables (Natural join).
- Now use this query to update the new column (just matching features will get updated).
- Use the new column for a thematic map visualizing empty columns.
