> The Reference Manual says that SYSCOLUMNS.COLUMNNAME has datatype CHAR(128). It's actual
datatype is VARCHAR(128). It's probably worth running the following script to confirm the
datatypes of all catalog columns described by the Reference Manual:
> connect 'jdbc:derby:memory:db;create=true';
> select cast(t.tablename as varchar( 20 )), cast(c.columnname as varchar(20)), c.columndatatype
> from sys.syscolumns c, sys.systables t
> where t.tablename like 'SYS%'
> and t.tableid = c.referenceid
> order by t.tablename, c.columnname;
