Those examples were just the tip of the iceberg. If you want some more: "SELECT 'A' = 'a'" returns true in MySQL Table names are case-sensitive in MySQL on Unix, but not on Windows. That must make your database very portable. "SELECT a, b, count(c) FROM d GROUP BY a" is legal syntax according to MySQL. If there are 2 rows with identical values for a, does that mean that MySQL just guesses which of the 2 values for B I want back? If I insert a NULL in a date field and then query it, I get back '0000-00-00'. I wonder which month that is? MySQL foreign keys can not enforce a relation between a 2 tables because they allow identical values in the parent table. >I can live with the trailing space issue.

Initially, Access should do just fine. And it is up to you to design the database in such a way that porting it is no problem. So don't use exotic datatypes like money (use numeric(12,2) instead), don't depend on non-standard functionality like the ability to generate UUIDs and you will be fine.
