select ProId,count(*) as row_count from member_collection where GroupId='products' GROUP BY ProId order by AccTime desc
连接数据表错误
错误代码： 1055:Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'alicejewelry.member_collection.AccTime' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
