Question

我的表結構是一樣的東西如下：

Table: Employee

<br><br> 
<pre> 
    <tr> 
    <td>EName</td> 
    <td>EId</td> 
    <td>DeptNo</td> 
    <td>DOJ</td> 
    </tr> 
    <br> 
    <tr> 
    <td>X</td> 
    <td>1</td> 
    <td>1</td> 
    <td>12/9/2013 2:47:35 AM</td> 
    </tr> 
    <br> 
    <tr> 
    <td>Y</td> 
    <td>2</td> 
    <td>2</td> 
    <td>12/9/2013 2:47:35 PM</td> 
    </tr> 
    <br> 
    <tr> 
    <td>Z</td> 
    <td>3</td> 
    <td>3</td> 
    <td>12/9/2013 8:25:45 AM</td> 
    </tr> 
    <br> 
    <tr> 
    <td>-</td> 
    <td>-</td> 
    <td>-</td> 
    <td>-</td> 
    </tr> 
    <br> 
</pre> 
.... 
<br> 

我要取誰在過去的10小時註冊員工名字......我該怎麼辦做它？

Answer 1

也許這將工作

SELECT ENAME FROM EMPLOYEE 
WHERE 
HOUR(TIMEDIFF(DATE_SUB(NOW(),INTERVAL 10 HOUR),NOW())) <= 10
