By Bruce Osborne on 11/2/2024

Ihis is a PGSQL course with other dialects just haphazardly "glued" on. Exercises are expected to be done in PGSQL with no solutions for the other dialects. Other dialects are not kept updated wither. I needed to troubleshoot inaccurate instructions for Oracle which USED to work but work no longer.
