简单的插入语句不能在PHP代码中工作。从MySQL工作台工作

Question

我有一个简单的脚本，我已经包括在这里。选择查询工作正常，但插入查询失败。我在我的macbook上运行php，apache和mysql。

表city_profile具有ID作为自动增量主键。并且名称是非空的。

function testMySQL() { 
    $db = new mysqli('localhost', 'root', NULL, 'citee'); 
    //$query = "select * from city_profile"; //this query works 
    $query = "insert into city_profile ('name','state','country') values ('charlotte','north carolina','usa')"; 
    //whereas the above one fails.. 
    $results = $db->query($query); 
    if($results) { 
    echo '<p>The query is successful.</p>'; 
    }else { 
    echo '<p>The query is NOT successful.</p>'; 
    } 

    //close the connection 
$db->close(); 
} 

Answer 1

尝试改变这一行：

$query = "insert into city_profile ('name','state','country') values ('charlotte','north carolina','usa')"; 

成这样：

$query = "insert into `city_profile` (`name`,`state`,`country`) values ('charlotte','north carolina','usa')";
