How do I get column type from table?

Question

I have this code:

select  a.id as tableid,
    a.name as tableName, 
    b.name as columnName,
    b.status as columnStatus,
    b.type as columnType
    from sysobjects a 
    LEFT JOIN syscolumns b
    ON a.id = b.id
    WHERE a.name = 'table_name'

Now, the columType shows numbers. I want to get the name of the columnType, which resides in column 'name' in table 'systypes'. How do I do that? Simple LEFT JOIN will result in duplicate rows.

I've seen in Sybase 15.0 and this is the code that you have to use:

select o.id [tableid], o.name [tableName], c.name [columnName], c.status [columnStatus], t.name [columnType] from sysobjects o
inner join syscolumns c on c.id = o.id
inner join systypes t on t.usertype = c.usertype
where o.type = 'U' and o.name in ('tablename')
