It all depends how you created the table - have you tried running the query by specifying you table name in uppercase such as:
j> select columnnumber, columnname, columndatatype
from sys.systables t, sys.syscolumns, sys.sysschemas s
where tableid=referenceid and t.schemaid=s.schemaid
and schemaname='SYS' and tablename='DATA'
order by columnnumber;
_or_ you can also run "select * from sys.systables" and find out if your table appears in the list being retrieved...then check the actual table identifier (aka name)...
Hope this helps a bit,

Hello,
I read this :
http://wiki.apache.org/db-derby/ListTableColumns
but I can't retreive the column of my table 'data'. Here is what i
tested :
ij> select columnnumber, columnname, columndatatype
from sys.systables t, sys.syscolumns, sys.sysschemas s
where tableid=referenceid and t.schemaid=s.schemaid
and schemaname='SYS' and tablename='data'
order by columnnumber;
And the result is :
COLUMNNUMB&|COLUMNNAME|COLUMNDATATYPE
