### Leer Un Hero { #read-one-hero }

</li>

<li>
The statement list of the selected case is executed.
</li>
</ol>

<p>
Since communication on <code>nil</code> channels can never proceed,
a select with only <code>nil</code> channels and no default case blocks forever.

var a []int
var c, c1, c2, c3, c4 chan int
var i1, i2 int
select {
case i1 = &lt;-c1:
	print("received ", i1, " from c1\n")

### Read One Hero { #read-one-hero }

### Helden lesen { #read-heroes }

Wir können `Hero`s aus der Datenbank mit einem `select()` **lesen**. Wir können ein `limit` und `offset` hinzufügen, um die Ergebnisse zu paginieren.

这里，我们使用 `SessionDep` 依赖项（一个 `Session` ）将新的 `Hero` 添加到 `Session` 实例中，提交更改到数据库，刷新 hero 中的数据，并返回它。

### 读取 Hero 类

我们可以使用 `select()` 从数据库中**读取** `Hero` 类，并利用 `limit` 和 `offset` 来对结果进行分页。

### 读取单个 Hero

我们可以**读取**单个 `Hero` 。
