mysql 搜索结果按照关键字排序

Jun 23, 2016 pm 01:48 PM
mysql Keywords sort search

现在需要搜索一个字段中包含:猪,狗,牛三个词的数据,
请问,怎么才能让结果按照指定关键词排序,比如让结果数据按照其中包含了猪的排在前面,包含了狗的排在第二,牛的排在第三。

例如:
猪啊
牛啊
狗啊
狗啊
猪啊
牛啊

要让结果排序变成
猪啊
猪啊
狗啊
狗啊
牛啊
牛啊

加上order by 字段1,字段2,字段3
{
      select * from   表名  order by 猪,狗,牛;


}应该就可以了

猪,狗,牛是在同一字段中的,楼上的不行。

可以这样写,例如字段名叫shengxiao

$sqlstr = "select *,IF(shengxiao='猪啊',1, IF(shengxiao='狗啊',2,3)) as s from table order by s";
Copy after login

加上order by 字段1,字段2,字段3
{
select * from 表名 order by 猪,狗,牛;


}应该就可以了


这样不行,猪,狗,牛不是字段,猪狗牛是数据
查询是这样的

$str="select id  from biaoqian  where (biaoti like '%猪%' or b.biaoti like '%狗%' or b.biaoti like '%牛%' or b.biaoti like '%猪狗牛%' )  order by  id desc limit 10";
Copy after login


现在的搜索结果排序方式是按id的倒序排列,我想按照搜索结果包含的数据排列,
包含 “猪狗牛”的排在第一,然后包含猪的排在第二,包含狗的排在第三,最后是包含牛的

create temporary table T  select '猪啊' as f  union select '牛啊'  union select '狗啊';select *, if(locate('猪', f), '猪',if(locate('牛',f),'牛', if(locate('狗',f),'狗',''))) as x  from T order by find_in_set(x, '猪,狗,牛')
Copy after login
f    x 猪啊 猪 狗啊 狗 牛啊 牛 
Copy after login

order by xx like '%猪%', xx   like '%狗%', xx like '%牛%' desc

搞定了,非常感谢
