Php Mysql命令从一个id到另一个id进行搜索

我想做的是从我的数据库中选择视频，视频=1，最大视频=25000，我有400k个视频，但我不想全部启动，所以我需要选择这种方式，我对搜索脚本执行此命令，但我认为它不起作用。。。希望有人能帮我解决这个问题

用于搜索的MySql命令（此命令用于显示找到的视频数量）：

在括号（）中添加类似于的

，尝试执行以下操作：

select count(some_id) as num from video where 
VID >= 1 AND VID <= 25000 AND 
(title LIKE '%key1%' or title LIKE '%key2%' or title LIKE '%key3%' or title LIKE '%key4%')

从视频中选择count（一些\u id）作为num，其中
VID>=1和VID请尝试以下操作：

select count(*) as num from video where VID BETWEEN 1 AND 25000 AND (title LIKE '%key1%' or title LIKE '%key2%' or title LIKE '%key3%' or title LIKE '%key4%') 

我认为您需要通过在AND子句中添加括号来使用运算符优先级

   select 
    count(*) as num 
    from 
        video 
    where 
        VID BETWEEN 1 AND 25000 
    AND 
        (title LIKE '%key1%' 
    or 
        title LIKE '%key2%' 
    or 
        title LIKE '%key3%' 
    or 
        title LIKE '%key4%' );

仅将所有标题比较设置在括号中

select 
  count(*) as num 
  from 
    video 
 where 
    VID BETWEEN 1 AND 25000 
 AND (
    title LIKE '%key1%' 
 or 
    title LIKE '%key2%' 
 or 
    title LIKE '%key3%' 
 or 
    title LIKE '%key4%' 
)

试试这个

 SELECT count(title) as num 
 FROM video 
 WHERE vid <= 25000 
 AND (title LIKE '%key1%' OR title LIKE '%key2%' OR title LIKE '%key3%' OR title LIKE '%key4%')

选择count（title）作为num
来自视频
当vid您的between做得很好时，真正的问题是您当前的脚本是这样执行的，因为AND运算符的优先级高于OR：

select 
count(*) as num 
from 
  video 
where 
  (VID BETWEEN 1 AND 25000 
AND 
  title LIKE '%key1%')
or 
  title LIKE '%key2%' 
or 
  title LIKE '%key3%' 
or 
  title LIKE '%key4%'

因此，您需要做的是如下更改：

select 
count(*) as num 
from 
  video 
where 
  VID BETWEEN 1 AND 25000 
AND (
  title LIKE '%key1%'
or 
  title LIKE '%key2%' 
or 
  title LIKE '%key3%' 
or 
  title LIKE '%key4%' )

试试这个

select 
    count(if(vid between 1 and 25000, 1, 0)) as totalvideocnt
from
    video
where
    (title like '%key1%' or title like '%key2%' or title like '%key3%' or title like '%key4%')

尝试：从视频中选择count（*）作为num，其中VID介于1和25000之间，并且（标题类似“%key1%”或标题类似“%key2%”或标题类似“%key3%”或标题类似“%key4%”我已在下面添加了答案
select 
    count(if(vid between 1 and 25000, 1, 0)) as totalvideocnt
from
    video
where
    (title like '%key1%' or title like '%key2%' or title like '%key3%' or title like '%key4%')
