At that point I will recommend you to use the API as I showed you in the
previous email. Also it's better to use the entire database (you will
need it for the API) and not only the gene/transcript/seq_region because
you can get more information quite easily.

The core database and the rnaseq database have different source of
information and different methods were used to generate the models. So
even if sometime the models from both databases are the same, the
stable_id will always be different. The only way to link them together
is with their coordinates.

If you looked for a perfect match for the start and end, it won't work.
You will need to use 2 separates queries. One to get the coordinates of
the transcript in the rnaseq database, the second one to get all the
gene in the core database between these coordinates and you might need
to widen the range.

As the boundaries will differ it will be a bit hard to find the right
one easily.

You will need the xref tables and the external_db table

g left join object_xref ox on g.gene_id = ox.ensembl_id left join xref x

x.external_db_id where e.db_name = "HGNC" and g.stable_id =
