簡單的插入語句不能在PHP代碼中工作。從MySQL工作臺工作

Question

我有一個簡單的腳本，我已經包括在這裏。選擇查詢工作正常，但插入查詢失敗。我在我的macbook上運行php，apache和mysql。

表city_profile具有ID作爲自動增量主鍵。並且名稱是非空的。

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

嘗試改變這一行：

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

成這樣：

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