我也在寻找相同的方法，最终在Helper类中创建了一个静态方法(在我的情况下，我将其命名为App\Helpers\Database)。

该方法

/**
 * Method to get the autoincrement value from a database table
 *
 * @access public
 *
 * @param string $database The database name or configuration in the .env file
 * @param string $table    The table name
 *
 * @return mixed
 */
public static function getAutoIncrementValue($database, $table)
{
    $database ?? env('DB_DATABASE');

    return \DB::select("
        SELECT AUTO_INCREMENT 
        FROM information_schema.TABLES 
        WHERE TABLE_SCHEMA = '" . env('DB_DATABASE') . "' 
        AND TABLE_NAME = '" . $table . "'"
    )[0]->AUTO_INCREMENT;
}

要调用该方法并获得MySql的AUTO_INCREMENT，只需使用以下命令:

$auto_increment = \App\Helpers\Database::getAutoIncrementValue(env('DB_DATABASE'), 'your_table_name');

希望能有所帮助。

如果你只是想知道这个数字，而不是在查询中得到它，那么你可以使用:

SHOW CREATE TABLE tablename;

您应该在底部看到auto_increment

查询一个给定模式下的所有表的AUTO_INCREMENT的“使用率”百分比(bigint类型unsigned列除外):

SELECT 
  c.TABLE_NAME,
  c.COLUMN_TYPE,
  c.MAX_VALUE,
  t.AUTO_INCREMENT,
  IF (c.MAX_VALUE > 0, ROUND(100 * t.AUTO_INCREMENT / c.MAX_VALUE, 2), -1) AS "Usage (%)" 
FROM 
  (SELECT 
     TABLE_SCHEMA,
     TABLE_NAME,
     COLUMN_TYPE,
     CASE 
        WHEN COLUMN_TYPE LIKE 'tinyint(1)' THEN 127
        WHEN COLUMN_TYPE LIKE 'tinyint(1) unsigned' THEN 255
        WHEN COLUMN_TYPE LIKE 'smallint(%)' THEN 32767
        WHEN COLUMN_TYPE LIKE 'smallint(%) unsigned' THEN 65535
        WHEN COLUMN_TYPE LIKE 'mediumint(%)' THEN 8388607
        WHEN COLUMN_TYPE LIKE 'mediumint(%) unsigned' THEN 16777215
        WHEN COLUMN_TYPE LIKE 'int(%)' THEN 2147483647
        WHEN COLUMN_TYPE LIKE 'int(%) unsigned' THEN 4294967295
        WHEN COLUMN_TYPE LIKE 'bigint(%)' THEN 9223372036854775807
        WHEN COLUMN_TYPE LIKE 'bigint(%) unsigned' THEN 0
        ELSE 0
     END AS "MAX_VALUE" 
   FROM 
     INFORMATION_SCHEMA.COLUMNS
     WHERE EXTRA LIKE '%auto_increment%'
   ) c

   JOIN INFORMATION_SCHEMA.TABLES t ON (t.TABLE_SCHEMA = c.TABLE_SCHEMA AND t.TABLE_NAME = c.TABLE_NAME)

WHERE
 c.TABLE_SCHEMA = 'YOUR_SCHEMA' 
ORDER BY
 `Usage (%)` DESC;

列出dbname所有tabename和AUTO_INCREMENT

SELECT `AUTO_INCREMENT`,`TABLE_NAME`
FROM  INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'dbname' ORDER BY AUTO_INCREMENT desc

我相信你正在寻找MySQL的LAST_INSERT_ID()函数。如果在命令行中，只需执行以下命令:

LAST_INSERT_ID();

你也可以通过SELECT查询得到这个值:

SELECT LAST_INSERT_ID();

Mysqli可执行示例代码:

<?php
    $db = new mysqli("localhost", "user", "password", "YourDatabaseName");
    if ($db->connect_errno) die ($db->connect_error);

    $table=$db->prepare("SHOW TABLE STATUS FROM YourDatabaseName");
    $table->execute();
    $sonuc = $table->get_result();
    while ($satir=$sonuc->fetch_assoc()){
        if ($satir["Name"]== "YourTableName"){
            $ai[$satir["Name"]]=$satir["Auto_increment"];
        }
    }
    $LastAutoIncrement=$ai["YourTableName"];
    echo $LastAutoIncrement;
?>
