> You can't use CREATE TABLE AS SELECT from a table with a BOOLEAN column. This 
> limitation was put in when CREATE TABLE AS SELECT was added. At that time you 
> could not create user tables with BOOLEAN columns and we did not want people 
> to be able to subvert that restriction by using CREATE TABLE AS SELECT from a 
> system table with BOOLEAN columns. The following script shows this problem:
> connect 'jdbc:derby:memory:db;create=true';
> create table t1( a int );
> create table t2( a boolean );
> create table t3 as select * from t1 with no data;
> create table t4 as select * from t2 with no data;
