OkCurl
======

_A curl for the next-generation web._

OkCurl is an OkHttp-backed curl clone which allows you to test OkHttp's HTTP engine (including
HTTP/2) against web servers.

To run locally, make sure you have GRAALVM_HOME set and run

```bash
./okcurl

    `str` と宣言されたものは、SQL の `TEXT`（データベースによっては `VARCHAR`）型の列になることを SQLModel は理解します。

### Engine の作成 { #create-an-engine }

SQLModel の `engine`（内部的には SQLAlchemy の `engine`）は、データベースへの接続を保持します。

同じデータベースに接続するために、コード全体で 1 つの `engine` オブジェクトを共有します。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}

* `Field(index=True)` 告訴 SQLModel 應為此欄位建立「SQL 索引」，以便在用此欄位過濾讀取資料時更快查詢。

    SQLModel 會知道宣告為 `str` 的欄位在 SQL 中會是 `TEXT`（或 `VARCHAR`，依資料庫而定）。

### 建立引擎 { #create-an-engine }

SQLModel 的 `engine`（底層實際上是 SQLAlchemy 的 `engine`）是用來「維護與資料庫連線」的東西。

你的程式中應該只有「單一 `engine` 物件」來連到同一個資料庫。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}
