在某些情况下,我在使用像关键字一样的mysql时遇到问题.我的要求是这样的.首先,当我搜索'ABC'时,结果应找到ABCABCdef,但不能找到xyzABCdefxyzABC.起初使用ABC%似乎很简单.但是在我搜索'heart%'的情况下,它不返回具有'liver heart'的行,因为它仅返回字符串开头具有heart的行.然后我尝试使用% heart%.此返回的行具有,但不是在字符串开头有心脏的那些行.我有点卡在这里..所以伙计们帮帮我.

I am having problem in using mysql like keyword in certain condition. My requirement goes like this.First, when i search for 'ABC', the result should find ABC and ABCdef but not xyzABCdef or xyzABC. It seems simple at first to use ABC%. but in condition when i search for 'heart%', it doesnot return row that have 'liver heart' because it returns only row that have heart at the beginning of the string.Then i tried using % heart%.This returned row having 'liver heart' but not those rows that have heart at the beginning of string. I am kind of stuck here..so guys help me.

编辑在您的帮助下,我提供了以下解决方案,但仍然给我带来了一些问题.

EDITWith your help guys i came with the following solution but still its giving me some problem.

    SELECT q.question_id, q.question, q.date,p.fname,p.lname,p.phys_id,
p.pic_path
            FROM questions q JOIN physiciansprofile p ON p.phys_id=q.phys_id
         WHERE  q.question  LIKE 'heart%' OR question LIKE '% heart%'
            AND q.question LIKE 'liver%' OR q.question LIKE '% liver%'
    ORDER BY q.date DESC LIMIT 0,10;

但是此查询也会返回heart failuresymptoms liver,对此是否有解决方案我需要获取同时包含heartliver的结果,并且还必须满足前面所述的条件.有什么要解决的吗

But this query return heart failure and symptoms liver as well.Is there any solution for this. I need to get result containing both heart and liver and also must satisfy condition as stated before. Is there any to solve this

推荐答案

'%heart%'无效,因为您要的是任何东西,再加上空间,再加上心脏,再加上任何东西.

'% heart%' doesn't work because you are asking for anything, plus space, plus heart, plus anything.

尝试类似的方法:

like 'heart%' OR like '% heart%'
