I was looking for examples on how to do this but I couldn't find it. I
tried a few variations of this:
# tbl_a, tbl_b, and tbl_c are Table objects
tables = [tbl_a]
chained_joins = tbl_a
collections = [tbl_b, tbl_c]
for tbl in collections:
tables.append(tbl)
chained_joins.outerjoin(tbl)
sql = select(tables).select_from(chained_joins)
Any hints are appreciated :)
Thanks!
