mysql先排序后分組？

用分組函數(shù)來做，假如你的表名是table_nameselect A.*from table_name A，(select product，max(date) max_date from table_name group by product) Bwhere A.product=B.product and A.date=B.max_date

Mysql分組并排序？

1、按rowno分組后，每個rowno只有一條數(shù)據(jù)。所以排序不可能同時按rowno， count來排序。

2、感覺你應(yīng)該只按count排序

------------------

SELECT rowno

，COUNT(*) AS Num

FROM Table1

GROUP BY rowno

ORDER BY COUNT(*)
