我有以下数据表(请参阅附图)。 image 我正在尝试使用超过2个表的内连接执行查询。以下是我的询问,请让我知道我在做错的地方。 我正在使用MS-Access。
SELECT Employees.Namee,WeekDay.DayName,Schedule.StartTime,Schedule.Hours FROM Schedule INNER JOIN Employees ON Schedule.Emp_ID = Employees.ID INNER JOIN WeekDay ON Schedule.Weekday = WeekDay.ID;
答案 0 :(得分:0)
请尝试以下代码
<div id="questions" class="hidden scoped-block">
<h1>Question <span id="currentQuestion"></span></h1>
<span id="question"><select id="optSelect"></select></span>
<div>
<a href="#">Restart quiz</a> -
<a href="#" id="nextQuestion">Next question</a>
</div>
</div>
<div id="results" class="hidden scoped-block">
<h1>results</h1>
<a href="#/">Restart quiz</a>
</div>
<div id="startPage" class="scoped-block">
<h1>Welcome to a small quiz</h1>
<p>
When you completed the quiz, you will be send to <a href="#/results">this</a> results page, which shouldn't be accessible before hand.
</p>
<p>
To start the quiz, click <a href="#/q=0">here</a>

当您有多个联接时,您需要括号。试试这个
SELECT Employees.Namee,WeekDay.DayName,Schedule.StartTime,Schedule.Hours FROM
(Schedule INNER JOIN Employees ON Schedule.Emp_ID = Employees.ID) INNER JOIN
WeekDay ON Schedule.Weekday = WeekDay.ID;
