Question

我有查询，它将计算哪个名字在字段中有一些数字并计算重复次数。结果是具有最多计数的名称。

我现在需要将此计数限制为10或15行，但是当我设置限制时它不起作用。

Select home, count(*) as count
from (select * from results where more='33' and name='FirstName' LIMIT 10) as limit10
group by home
order by count(more) desc
LIMIT 1;

我尝试使用LEAST，但同样如此。我现在按日期添加顺序，计算exec的最后一行，但是它相同......

Select home, LEAST( count(*), 12) as count
from (SELECT *,STR_TO_DATE(date, '%d.%m.%Y') as datum FROM results where more='33' and name='FirstName' ORDER BY datum desc) as limit12
group by home
order by count(more) desc
LIMIT 1;

Answer 1

我建议您使用LEAST功能：

Select home, LEAST( count(*), 10 ) as count
from results where more='33' and name='FirstName'
group by home
order by count(more) desc
LIMIT 1;

这将获得相同的最终结果，并作为额外的奖励，你摆脱该子查询
