Php Mysql在一个数据库中加入两个查询

我有两个查询：第一个查询将检索延迟最大的5个用户，我正在while循环中运行第二个查询，用于检索用户的用户名和名称。 这就是它的样子：

select UserID, SUM(delay) as 'TOTdelay' FROM logboek WHERE date >= x AND date <= y GROUP BY UserID ORDER BY TOTdelay DESC LIMIT 5
while ($stmt->fetch()) {
   select Username, Name FROM users WHERE ID = $UserID LIMIT 1;
   echo $Username.' on the x place with a total delay of '.$TOTdelay;
}

如何将这2个查询合并为1，这样就不必在while循环中运行查询

谢谢你帮助我

你能帮我做一个梦吗？

SELECT
  Username,
  Name,
  SUM(delay) AS `TOTdelay`
FROM
  logboek
INNER JOIN
  users ON UserId = users.ID
WHERE
  date BETWEEN 20130101 AND CURDATE()
GROUP BY
  UserID
ORDER BY
  TOTdelay DESC
LIMIT 5

select logboek.UserID, SUM(logboek.delay) as 'TOTdelay', users.Username, users.Name FROM logboek
LEFT JOIN users on (users.id = logboek.UserID)
 WHERE logboek.date >= x AND logboek.date <= y GROUP BY logboek.UserID ORDER BY TOTdelay DESC LIMIT 5
