H2 vs MYSQL differences.

	To minimize the differences:
	1. On the JDBC connection string: 'MODE=MySQL', full example jdbc:h2:mem:test_one;DB_CLOSE_DELAY=-1;MODE=MySQL;DB_CLOSE_ON_EXIT=FALSE;IGNORECASE=TRUE;
	2. Interactive SQL: SET MODE MySQL;

	H2 does not like multiple 'ADD COLUMN' commands for one ALTER TABLE.

	In mysql the following works
	ALTER TABLE SOME_TABLE
	ADD COLUMN USER VARCHAR(64) NOT NULL SET DEFAULT '',
	ADD COLUMN DESCRIPTION VARCHAR(1024) NOT NULL SET DEFAULT '' AFTER USER,
