Running multiple CREATE TABLE statements in redshift online query editor each ending with ';' is resulting only one table being created.

I looked at various posts on stack overflow where multiple tables were created on other platforms. Such as mysql here: SQL Create multiple tables at once. However, I have not been able to find an example for redshift that works. I also tried to remove the last ';' which resulted in only the first table being created.

CREATE TABLE IF NOT EXISTS test_one (
  test_col varchar(30),
  test_two varchar(30)

CREATE TABLE IF NOT EXISTS test_two (
  test_col varchar(30),
  test_two varchar(30)
);

There are no error codes, but only test_two is created.
