Question

I would rather not drop my table entirely to create a new one, but I need to change the ENGINE type from MYISAM to INNODBfor foreign key contraints.

• Can I do this on the fly with an Alter table? Or do I have to start from scratch with a new table?

• Would it matter if I already had data in that table which needs to be altered / dropped & recreated ?

Answer 1

From the manual:

    ALTER TABLE t1 ENGINE=InnoDB;
