I have some SQL I need to get working on SQL 2005/2008. The SQL is from SQL 2000 and uses some system objects to make it work.

master.dbo.spt_provider_types
master.dbo.syscharsets systypes syscolumns sysobjects

I know SQL 2005 does no longer use system tables and I can get the same information from views, but I am looking for a solution that will work for both SQL 2000 and 2005/2008. Any ideas?

    select top 100 percent
        TABLE_CATALOG       = db_name(),
        TABLE_SCHEMA        = user_name(o.uid),
        TABLE_NAME      = o.name,
        COLUMN_NAME     = c.name,
        ORDINAL_POSITION    = convert(int,
                       (
                        select count(*)
                        from syscolumns sc
                        where sc.id     =  c.id
                          AND sc.number =  c.number
                          AND sc.colid  <= c.colid
                        )),
        IS_COMPUTED = convert(bit, c.iscomputed)

    from
        syscolumns c left join syscomments m on c.cdefault = m.id and m.colid = 1,
        sysobjects o,
        master.dbo.spt_provider_types d,
        systypes t,
        master.dbo.syscharsets      a_cha /* charset/1001, not sortorder.*/
    where
        o.name = @table_name and
        permissions(o.id, c.name) <> 0
    and     (o.type in ('U','V','S') OR (o.type in ('TF', 'IF') and c.number = 0))
    and     o.id = c.id
    and     t.xtype = d.ss_dtype
    and     c.length = case when d.fixlen > 0 then d.fixlen else c.length end
    and     c.xusertype = t.xusertype
    and a_cha.type = 1001 /* type is charset */
    and a_cha.id = isnull(convert(tinyint, CollationPropertyFromID(c.collationid, 'sqlcharset')),
            convert(tinyint, ServerProperty('sqlcharset'))) -- make sure there's one and only one row selected for each column
    order by 2, 3, c.colorder

) tbl where IS_COMPUTED = 0
