颜色属性在离子2中不起作用.颜色在普通IONIC标签中起作用,但在HTM1标签中起作用.你能帮忙吗？代码写在下面.

<ion-content>
<div class="page-home">
<h1 color="secondary">LOGO</h1>
<br/>
<br/>
<p color="danger">Sign in with social media account</p>
<div id="socialLogin">
  <img src="assets/icon/fb.svg" />
  <img src="assets/icon/tw.svg" />
  <img src="assets/icon/goo.svg" />
</div>
<ion-list>
  <ion-item>
    <ion-label floating color="secondary">Username</ion-label>
    <ion-input type="text"></ion-input>
  </ion-item>
  <ion-item>
    <ion-label floating>Password</ion-label>
    <ion-input type="password"></ion-input>
  </ion-item>
</ion-list>
<br/>
<br/>
<button ion-button full icon-left> <ion-icon name="log-in"></ion-icon>Login</button>

<button ion-button clear>Register</button>/
<button ion-button clear>Forgot Passowrd</button>
 </div>

</ion-content>

我写了这个SQL查询:

select first_name, salary 
from employees 
where salary in( select distinct top(10) salary from employees order by salary  disc );

当我运行它时,我收到此错误:

SQL错误:ORA-00907:缺少右括号00907. 00000 - "缺少右括号"

什么可能导致错误？
