["James F. Adams (JIRA)" <ji...@apache.org>]

James F. Adams updated DERBY-2605:
----------------------------------

    Attachment: d2605_v1.stat
                d2605_v1.patch

Attached is a patch that addresses the ability to create columns where the data type of the column is currently for internal use or otherwise not exposed to the user.

I added an isInternalTypeId method to TypeId and defined the following types as being for internal use:

BOOLEAN
NATIONAL CHAR
NATIONAL LONGVARCHAR
NATIONAL VARCHAR
REF
TINYINT
USERDEFINED
NCLOB

CreateTableNode was updated to use this method to check the data type of each column.
A new message was added.
A new test was added.

This patch does not address the situation with the VALUES statement desribed by Army.  I am wondering if the VALUES statement should even be allowed to create rows with invalid decimal precision.

> The work on DERBY-64 seems to have opened up a wormhole by which you can create user tables with BOOLEAN columns. The following script shows how to do this:
> drop table foo;
> create table foo
> as select systemalias from sys.sysaliases with no data;
> rename column foo.systemalias to boolcol;
> alter table foo
>   alter column boolcol null;
> select c.columndatatype
> from sys.syscolumns c, sys.systables t
> where t.tableid=c.referenceid
> and t.tablename='FOO';
> insert into foo( boolcol )
> values
> ( 0 ),
> ( 1 ),
> ( cast (null as int) )
> ;
> select * from foo;
