Question

我从未遇到过像这样的问题。我在mysql中使用简单的搜索查询（wamp）我的查询是这样的

SELECT * FROM `members` WHERE `m_email`='heena@gmail.com';

如果我要更改值

，

即使不起作用

SELECT * FROM `members` WHERE `m_email`='heena';

获得类似

的输出

MySQL returned an empty result set (i.e. zero rows). ( Query took 0.0012 sec )

但如果我要去

SELECT * FROM `members` WHERE `m_id`=5 ;
//successful and showing output.

 see here the values in table in mysql(wamp)
Edit    Delete  5   heena   e7f4a1abdd69d6c9a5b3f8b8736ea2f3    956333652   0   female   


 here is the structure for m_email field
m_email     varchar(30)     latin1_swedish_ci       No  None

Answer 1

试试这个

SELECT * FROM `members` WHERE trim(`m_email`)='heena@gmail.com';

OR

SELECT * FROM `members` WHERE trim(`m_email`)='heena';

搜索查询不起作用mysql（wamp）
