+# Prisma 连接 OceanBase 指南
+
+[English](README.md) | 简体中文
+
+本文介绍如何通过 [Prisma](https://www.prisma.io) 连接 [OceanBase](https://www.oceanbase.com) 数据库。
+
+## 准备工作
+
+确保 Nodejs 和 npm 已经安装。
+
+## 项目配置
+
+拉取项目并进入相应目录:
+
+```bash
+git clone [email protected]:oceanbase/ob-samples.git
+cd javascript/prisma
+```
+
+全局配置环境变量 (原因详见 https://open.oceanbase.com/blog/15137753618):
+
+```bash
+export PRISMA_ENGINES_MIRROR=https://oceanbase-prisma-builds.s3.ap-southeast-1.amazonaws.com
+export BINARY_DOWNLOAD_VERSION=96fa66f2f130d66795d9f79dd431c678a9c7104e
+```
+
+安装依赖 (注意 `prisma` 和 `@prisma/client` 版本在 `^5.20.0` 及以上):
+
+```bash
+npm install
+```
+
+修改 `.env` 中的数据库连接串，格式如下。注意需要设置 `prefer_socket=false`，以避免和 OceanBase 建立连接时报错。
+
+```bash
+DATABASE_URL="mysql://username:password@localhost:3306/test?prefer_socket=false"
+```
+
+执行以下命令，将 `prisma/schema.prisma` 中定义的 `User`、`Post` 和 `Profile` 数据模型同步到 OceanBase 数据库中:
+
+```bash
+npx prisma migrate dev --name init
+```
+
+```sql
+mysql> show tables;
++--------------------+
+| Tables_in_test     |
++--------------------+
+| _prisma_migrations |
+| posts              |
+| profiles           |
+| users              |
++--------------------+
+4 rows in set (0.02 sec)
+```
+
+使用命令行执行 `index.ts` 中的示例代码:
+
+```bash
+npx ts-node index.ts
+```
+
+输出以下内容，说明执行成功:
+
+```bash
+[
+  {
+    id: 1,
+    email: '[email protected]',
+    name: 'Alice',
+    posts: [
+      {
+        id: 1,
+        createdAt: 2024-10-31T04:33:45.535Z,
+        updatedAt: 2024-10-31T04:33:45.535Z,
+        title: 'Hello World',
+        content: null,
+        published: false,
+        authorId: 1
+      }
+    ],
+    profile: { id: 1, bio: 'I like turtles', userId: 1 }
+  }
+]
+```
+
+查看对应的 `users`、`posts` 和 `profiles` 表，数据已正常插入:
+
+```bash
+mysql> select * from users;
++----+---------------------+-------+
+| id | email               | name  |
++----+---------------------+-------+
+|  1 | [email protected] | Alice |
++----+---------------------+-------+
+1 row in set (0.01 sec)
+
+mysql> select * from posts;
++----+-------------------------+-------------------------+-------------+---------+-----------+----------+
+| id | createdAt               | updatedAt               | title       | content | published | authorId |
++----+-------------------------+-------------------------+-------------+---------+-----------+----------+
+|  1 | 2024-10-31 04:33:45.535 | 2024-10-31 04:33:45.535 | Hello World | NULL    |         0 |        1 |
++----+-------------------------+-------------------------+-------------+---------+-----------+----------+
+1 row in set (0.01 sec)
+
+mysql> select * from profiles;
++----+----------------+--------+

++----+----------------+--------+
+|  1 | I like turtles |      1 |

+# Connect to OceanBase with Prisma
+
+English | [简体中文](README-CN.md)
+
+This document describes how to connect to [OceanBase](https://www.oceanbase.com) with [Prisma](https://www.prisma.io).
+
+## Preparation
+
+Make sure `Node.js` and `npm` are installed.
+
+## Configuration
+
+Clone the project and navigate to the appropriate directory:
+
+```bash
+git clone [email protected]:oceanbase/ob-samples.git
+cd javascript/prisma
+```
+
+Set the global environment variables (for reasons see https://open.oceanbase.com/blog/15137753618):
+
+```bash
+export PRISMA_ENGINES_MIRROR=https://oceanbase-prisma-builds.s3.ap-southeast-1.amazonaws.com
+export BINARY_DOWNLOAD_VERSION=96fa66f2f130d66795d9f79dd431c678a9c7104e
+```
+
+Install dependencies (note that the versions of `prisma` and `@prisma/client` should be `^5.20.0` or higher):
+
+```bash
+npm install
+```
+
+Modify the connection string in the `.env` file, formatted as follows. Note that `prefer_socket=false` must be set to avoid errors when connecting to OceanBase.
+
+```bash
+DATABASE_URL="mysql://username:password@localhost:3306/test?prefer_socket=false"
+```
+
+Execute the following command to synchronize the `User`, `Post` and `Profile` data models defined in `prisma/schema.prisma` to the OceanBase:
+
+```bash
+npx prisma migrate dev --name init
+```
+
+```sql
+mysql> show tables;
++--------------------+
+| Tables_in_test     |
++--------------------+
+| _prisma_migrations |
+| posts              |
+| profiles           |
+| users              |
++--------------------+
+4 rows in set (0.02 sec)
+```
+
+Execute `index.ts` from the command line:
+
+```bash
+npx ts-node index.ts
+```
+
+The output should be as follows, indicating successful execution:
+
+```bash
+[
+  {
+    id: 1,
+    email: '[email protected]',
+    name: 'Alice',
+    posts: [
+      {
+        id: 1,
+        createdAt: 2024-10-31T04:33:45.535Z,
+        updatedAt: 2024-10-31T04:33:45.535Z,
+        title: 'Hello World',
+        content: null,
+        published: false,
+        authorId: 1
+      }
+    ],
+    profile: { id: 1, bio: 'I like turtles', userId: 1 }
+  }
+]
+```
+
+Check the corresponding `users`, `posts` and `profiles` tables and the data has been inserted correctly:
+
+```bash
+mysql> select * from users;
++----+---------------------+-------+
+| id | email               | name  |
++----+---------------------+-------+
+|  1 | [email protected] | Alice |
++----+---------------------+-------+
+1 row in set (0.01 sec)
+
+mysql> select * from posts;
++----+-------------------------+-------------------------+-------------+---------+-----------+----------+
+| id | createdAt               | updatedAt               | title       | content | published | authorId |
++----+-------------------------+-------------------------+-------------+---------+-----------+----------+
+|  1 | 2024-10-31 04:33:45.535 | 2024-10-31 04:33:45.535 | Hello World | NULL    |         0 |        1 |
++----+-------------------------+-------------------------+-------------+---------+-----------+----------+
+1 row in set (0.01 sec)
+
+mysql> select * from profiles;
++----+----------------+--------+
+| id | bio            | userId |
++----+----------------+--------+
+|  1 | I like turtles |      1 |
++----+----------------+--------+
+1 row in set (0.01 sec)
+```
