Question: I would like to get all the fields in a database, `information_schema` is not available.

However, I can show the fields of a single table using

`show columns from table`

How can I add another show command?
I tried `UNION`, but it gives me syntax error.

Answer: 
If you have a solid background color try this

```css
body {
  background: grey;
  margin: 0;
}

.container {
  width: 100%;
  height: 200px;
  background: url("http://lorempixel.com/1000/300/nature/3");
  background-size:cover;
}

.content {
  height: 100px;
  color: #fff;
}

.shape {
  position: relative;
  height: 100px;
  overflow:hidden;
}

.shape:after {
  content: "";
  position: absolute;
  width: 40%;
  height: 100%;
  background: grey;
  top: 0;
  transform: skew(30deg);
  left: -10%;
}

.shape:before {
  content: "";
  position: absolute;
  width: 40%;
  height: 100%;
  background: grey;
  top: 0;
  transform: skew(-30deg);
  right: -10%;
}
```

```html
<div class="container">
  <div class="content">
    Contents
  </div>
  <div class="shape"></div>
</div>
```
Depending on the [browser support](https://developer.mozilla.org/en/docs/Web/CSS/clip-path#Browser_compatibility) needed, You can use clip-path:

```css
#trapezoid {
  background: url(https://upload.wikimedia.org/wikipedia/commons/8/83/Jho_Arce_User_Profile_Image.jpg) no-repeat;
  background-size: cover;
  height: 100px;
  width: 200px;
  margin: auto;
  -webkit-clip-path: polygon(100% 0, 100% 70%, 70% 100%, 30% 100%, 0% 70%, 0 0);
  clip-path: polygon(100% 0, 100% 70%, 70% 100%, 30% 100%, 0% 70%, 0 0)
}

body {
  background: silver;
}
```

```html
<div id="trapezoid"></div>
```
