Hm. This problem may not be as bad as you think. Most of the basics are the same between DBMS's. The biggest differences I have noticed between MySQL and other DBMS systems is that MySQL lets you insert records using the update syntax:
INSERT INTO table SET field1=value1, field2=value2
and others don't really support that.
I'm sure there's other stuff, but if you're only talking about one table, things might not be so bad.
