我有一个看起来像这样的表:
var arDrone = require('ar-drone');
var client = arDrone.createClient();
// Flat trim.
client.ftrim();
我想得到这样的结果:
date | title | count
------+-------+-------
04/20 | foo | 420
04/20 | bar | 194
04/21 | foo | 23
04/21 | bar | 100
如何在Redshift SQL中执行此操作?谢谢!

我认为最简单的方法是使用group by with group:
<div class="box">
<div class="chip">Chip1</div>
<div class="chip">Chip2</div>
<div class="chip">Chip3</div>
<div class="chip">Chip4</div>
<input class="textbox" type="text">
</div>
<br>
<div class="box">
<div class="chip">Chip1</div>
<div class="chip">Chip2</div>
<div class="chip">Chip3</div>
<div class="chip">Chip4</div>
<div class="chip">Chip5</div>
<div class="chip">Chip6</div>
<div class="chip">Chip7</div>
<div class="chip">Chip8</div>
<div class="chip">Chip9</div>
<input class="textbox" type="text">
</div>
