To see which storage engines your server supports, use the SHOW ENGINES;.

CREATE TABLE [db name].[table name] (...) ENGINE = InnoDB;
ALTER TABLE [db name].[table name] ENGINE = MyISAM;

The build-in default value of the storage_engine system variable is MyISAM.
The default storage engine can be specified at server startup with the --default-storage-engine option.
SET GLOBAL storage_engine = [engine name]; if you have the SUPER privilege.
SET SESSION storage_engine = [engine name];
SET storage_engine = [engine name];
