--创建测试环境
create table 表(Name varchar(10),FuckDate datetime,MMName varchar(10),FuckPlace varchar(10))
--插入测试数据
insert 表(Name,FuckDate,MMName,FuckPlace)
select 'LZ ', '2007-03-08 ', 'Lily ', 'Home ' union all
select 'LZ ', '2007-03-09 ', 'Lily ', 'Hotel ' union all
select 'LZ ', '2007-03-15 ', 'Lisa ', 'Home ' union all
select 'LZ ', '2007-03-20 ', 'Lily ', 'Car ' union all
select 'LZ ', '2007-03-21 ', 'Lily ', 'Street '
--求解过程
select top 1 'LZ like '+mmname+ ' best.often in '+fuckplace from 表
where name= 'lz '
group by all mmname,fuckplace
order by count(*) desc
--删除测试环境
drop table 表
/*--测试结果
