分页 模糊查询

 serversql 分页查询，按匹配精准度排序

SELECT
    S_INFO_WINDCODE,
    S_INFO_CODE,
    S_INFO_NAME,
    S_INFO_COMPNAME,
    S_INFO_COMPNAMEENG,
    S_INFO_EXCHMARKET,
    S_INFO_LISTBOARD,
    S_INFO_LISTDATE,
    S_INFO_DELISTDATE,
    S_INFO_PINYIN,
    S_INFO_LISTBOARDNAME,
    S_INFO_COMPCODE 
FROM  AShareDescription 
WHERE  S_INFO_WINDCODE LIKE '%${sInfoWindcode}%' 
ORDER BY 
                (case 
                         when S_INFO_WINDCODE='${sInfoWindcode}'      then 1
                         when S_INFO_WINDCODE like '${sInfoWindcode}%'  then 2
                         when S_INFO_WINDCODE like '%${sInfoWindcode}%' then 3
                         when S_INFO_WINDCODE like '%${sInfoWindcode}'  then 4
                         else 5
                 end)  ASC
OFFSET '${startNum}' ROWS FETCH NEXT '${startSize}' ROWS ONLY

MySQL  根据字符的长度排序，name 字段使用关键字模糊查询之后，再使用char_length函数，获取 name 字段的字符长度，然后按长度升序。

sql ：如下

select * from brand where name like '%苏三%' 
order by char_length(name) asc, locate('苏三',name) asc limit 5,5;
