The MySQL import function works, but it does not seem to support certain things that are reasonably common in MySQL schema dumps, like the following:
*UNSIGNED integers.
- Chained ALTER TABLE statements, like this:
ALTER TABLE foo
ADD COLUM foo VARCHAR,
ADD COLUMN bar VARCHAR; - ALTER TABLE ADD UNIQUE KEY
- ALTER TABLE MODIFY
- ALTER TABLE ADD CONSTRAINT
So in general it boils down to issues with the variants on ALTER TABLE, and using UNSIGNED integers.
