关于dbchart的问题(100分)

我在程序中使用了一个DBchart.该dbchart的dateset为一个query,其SQL语句
如下：
select sum(物品进口数量) as col, month(rq) as mon
from 表名
group by mon
说明：该表为一进货表，每天一条记录，物品进口数量以及rq均为字段名
物品进口数量为integer,rq为date型
想对该物品按月统计总数，并用图形的方法显示，但是显示结果并不是
按月份大小顺序排列的，如果在SQL中加order by mon 则出错，请各位大侠指教
(数据库用的是SYbase SQLAnywhere)
另外请教各位：用Sybase SQLAnywhere 是否必须通过 ODBC 进行连接。

Can this sentence:

select sum(物品进口数量) as col, month(rq) as mon from 表名 group by mon
order by 2

do the work? (Some SQL does not support order by a field's
name, while the field is a result of a arithmatic fomulation)

Borland SQL Links may support Sybase SQLAnywhere

pegasus ,第一个问题如您所说，已经解决，感谢了，先预加您老人家50分
不过能否对 SQL links 的用法详细解释一下，小弟拜托了

Hehe, thank you.

SQL Links is a driver for BDE that Borland designed to connect data
base. (Borland Database Engine).

I remember when Microsoft has not provide a good ODBC driver for its
own SQL Server, (not so good because it can't let you get BIN data
from SQL Server, but you do can store data into it), I use Borland's
SQL Links instead to connect SQL Server, and it worked fine,

接受答案了.
