Question

这是我目前的查询。

SELECT com.commisionAmount, stu.studentName, pay.paymentDate, pay.paymentAmount
FROM `commisions` as com INNER JOIN `accounts` as acc ON com.commisionAccount = acc.id 
INNER JOIN `studentpayments` as pay ON com.paymentID = pay.id 
INNER JOIN `students` as stu ON pay.paymentStudent = stu.id 
WHERE pay.paymentDate BETWEEN '$startdate' AND '$enddate' AND acc.id = '$id'

我还想在执行此查询时选择stu.signedUpBy ...它是一个引用acc.id的ID，但我希望它显示附加到该ID的acc.username。我最好怎么做？我尝试将其作为内连接，但它无法正常工作。错误的结果

SELECT com.commisionAmount, stu.studentName, pay.paymentDate, pay.paymentAmount, acco.username
FROM  `commisions` AS com
INNER JOIN  `accounts` AS acc ON com.commisionAccount = acc.id
INNER JOIN  `studentpayments` AS pay ON com.paymentID = pay.id
INNER JOIN  `students` AS stu ON pay.paymentStudent = stu.id
INNER JOIN `accounts` AS acco ON stu.signedUpBy = acc.id
WHERE pay.paymentDate
BETWEEN  '2016-08-01'
AND  '2016-10-31'
AND acc.id =  '46'

如果我理解正确，您只需要向帐户添加另一个<nav id="nav"><div class="menu-main-menu-container"><ul id="menu-main-menu" class="menu"><li id="menu-item-5164" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-home menu-item-5164"><a href="#">Home</a></li> <li id="menu-item-2787" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-2756 current_page_item menu-item-has-children menu-item-2787"><a href="#">Portfolio</a> <ul class="sub-menu"> <li id="menu-item-4602" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-4602"><a href="#">Link one</a></li> <li id="menu-item-5628" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-5628"><a href="#">Link two</a></li> <li id="menu-item-1023" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-1023"><a href="#">Link three</a></li> <li id="menu-item-363" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-363"><a href="#">Link four</a></li> <li id="menu-item-1022" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-1022"><a href="#">Link five</a></li> <li id="menu-item-362" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-362"><a href="#">Link six</a></li> </ul> </li> <li id="menu-item-356" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-has-children menu-item-356"><a href="#">About</a> <ul class="sub-menu"> <li id="menu-item-5709" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-5709"><a href="#">Another Link 1</a></li> <li id="menu-item-358" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-358"><a href="#">Another Link 2</a></li> <li id="menu-item-4883" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-4883"><a href="#">Another Link 3</a></li> <li id="menu-item-835" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-835"><a href="#">Another Link 4</a></li> </ul> </li> <li id="menu-item-364" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-has-children menu-item-364"><a href="#">Our clients</a> <ul class="sub-menu"> <li id="menu-item-4709" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-4709"><a href="#">Case Studies</a></li> </ul> </li> <li id="menu-item-357" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-357"><a href="#">Blog</a></li> <li id="menu-item-360" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-360"><a href="#">Contact</a></li> </ul></div></nav>即可。然后，您可以输入用户名：

JOIN

如何使用其他查询将列添加到我的查询？
