Question

我有这个SQL查询。如果我在没有LIMIT的情况下运行此查询，匹配的结果就可以了，但是当我使用限制运行时（进行无限滚动），我无法获得最佳匹配，只是我获得LIMIT搜索的最佳匹配，而不是10中分开的整个搜索中的第一个：

    SELECT videos.id_video as idVideo, 1 as idCanal, MATCH (nombre_prog, programas.descrip_larga) AGAINST ('escuela') as relevancia FROM videos
INNER JOIN programas_videos ON videos.id_video = programas_videos.id_video
INNER JOIN programas ON programas_videos.id_prog = programas.id_prog
WHERE MATCH (nombre_prog, programas.descrip_larga) AGAINST ('escuela' IN BOOLEAN MODE)
ORDER BY relevancia DESC LIMIT 5,5

我该如何纠正？

谢谢！

试试这个。它将首先返回子选择的所有结果，然后应用限制。

SELECT  *

FROM 

(
SELECT videos.id_video as idVideo, 1 as idCanal, MATCH (nombre_prog, programas.descrip_larga) AGAINST ('escuela') as relevancia FROM videos
INNER JOIN programas_videos ON videos.id_video = programas_videos.id_video
INNER JOIN programas ON programas_videos.id_prog = programas.id_prog
WHERE MATCH (nombre_prog, programas.descrip_larga) AGAINST ('escuela' IN BOOLEAN MODE)
ORDER BY relevancia DESC 
) AS x

LIMIT 5,5

Mysql LIMIT使用MATCH AGAINST
