### 讀取多個 Hero { #read-heroes }

我們可以用 `select()` 從資料庫「讀取」多個 `Hero`。可以加入 `limit` 與 `offset` 來分頁。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[48:55] hl[51:52,54] *}

### 讀取單一 Hero { #read-one-hero }

我們可以「讀取」單一的 `Hero`。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[58:63] hl[60] *}

### 刪除 Hero { #delete-a-hero }

我們也可以「刪除」一個 `Hero`。

- The new `-gce-zones` flag on the `e2e.test` binary instructs tests that check for information about how the cluster interacts with the cloud to limit their queries to the provided zone list. If not specified, the current behavior of asking the cloud provider for all available zones in multi zone clusters is preserved.
