如何获取最后一个插入ID

INSERT INTO `cscart_static_data` ( `param_id` , `param` , `param_2` , `param_3` , 
`param_4` , `param_5` , `section` , `status` , `position` , `parent_id` , `id_path` , 
`localization` , `company_id` ) 
   VALUES ('','index.php?dispatch=postview.view', '', '', '', '1', 'A', 'A', '0', 
           '0', '152', '', '1' ); 

INSERT INTO `cscart_static_data_descriptions` ( `param_id` , `lang_code` , `descr` )
 VALUES ( SELECT LAST_INSERT_ID(), 'en', 'Blog' );

此处，第二个查询对我不起作用，因为 'SELECT LAST_INSERT_ID()' 为空。如何解决

Answer 1

$sql = INSERT INTO `cscart_static_data` ( `param_id` , `param` , `param_2` , `param_3` , `param_4` , `param_5` , `section` , `status` , `position` , `parent_id` , `id_path` , `localization` , `company_id` ) VALUES ('','index.php?dispatch=postview.view', '', '', '', '1', 'A', 'A', '0', '0', '152', '', '1' ); 
 mysql_query($sql);
 $last_insert_id = mysql_insert_id();

现在在您的选择查询中使用此“ $ last_insert_id ”

Answer 2

在PHP语言中，有一个函数可用，即mysqli_insert_id（）。借助此函数，您可以从表中获取最后插入的id。

 <!DOCTYPE html>
 <html>
<body>
    <?php
    $con = mysqli_connect('localhost', 'root', '','test');
    //$db = mysqli_select_db('test', $con);
    echo 'Date = '.date('Y-M-d H:i:s')."<br/>";
    $sql = "INSERT INTO `sample`(`name`, `address`, `date`) VALUES ('Pabitra','Kolkata'," . strtotime(date('Y-M-d H:i:s')) . ")";
    echo $sql;
    if (mysqli_query($con,$sql)) {
        echo "Insert successfully";
    }else{
        echo 'error eccured.';
    }
    ?>
    <?php
    $id = mysqli_insert_id($con);
    $sql = "select * from sample where id = ".$id;
    $result = mysqli_query($con,$sql);
    $row = mysqli_fetch_array($result,MYSQLI_ASSOC);
         print_r($row);
    $myXMLData = "<?xml version='1.0' encoding='UTF-8'?>
    <note>
    <id>".$id."</id>
    <name>".$row['name']."</name>
    <address>".$row['address']."</address>
    <date>".date('Y-M-d H:i:s',strtotime($row['date']))."</date>
    </note>";

    $xml = simplexml_load_string($myXMLData) or die("Error: Cannot create object");
    print_r($xml);
    ?>

</body>

试试这个..

<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
mysql_select_db('mydb');

mysql_query("INSERT INTO mytable (product) values ('kossu')");
printf("Last inserted record has id %d\n", mysql_insert_id());
?>
