I have two tables that contain records about road construction activites:

1. table_a is the master list.
2. table_b is a legacy list.

For each road, in each year, I want to select the records from table_b that do not already exist in table_a.

Also, the records should not overlap spatially along the road. More specifically, the from_m and to_m of the records in table_b should not overlap the from_m and to_m in table_a.

The data in Excel (for easy viewing):

Here is what the data looks like in Excel:

Note: I'm getting an error from IMGUR when I try to upload my images: Failed to upload image; imgur is rejecting the request. I'm going to try again from another device shortly.

In the meantime, here is an alternative link to the screen capture: https://ibb.co/fynWve

The records in green should be selected by the query; the records in red should not.

How can I do this? I do not have Oracle Spatial.

The DDL:

Table A:

    id number(4,0), 
    road_id number(4,0), 
    year number(4,0), 
    from_m number(4,0), 
    to_m number(4,0)
   );

insert into table_a (id,road_id,year,from_m,to_m) values (1,1,2000,0,100);
insert into table_a (id,road_id,year,from_m,to_m) values (2,1,2005,0,25);
