+# Golang 连接 OceanBase 指南（使用 go-sql-driver/mysql）
+
+[English](README.md) | 简体中文
+
+本文介绍如何通过 `go-sql-driver/mysql` 连接 OceanBase 数据库。
+
+关于 `go-sql-driver/mysql` 的详细信息，您可参考 [https://github.com/go-sql-driver/mysql](https://github.com/go-sql-driver/mysql)。
+
+## 快速开始
+
+您需要使用 dataSourceName 来创建数据库连接，详细信息请参考 [go-sql-driver/mysql 文档](https://github.com/go-sql-driver/mysql#dsn-data-source-name)。
+
+以 [Test.go](Test.go) 代码为例
+
+```go
+var (
+   host     = "127.0.0.1"
+   port     = 2881
+   dbName   = "test"
+   username = "root@test"
+   password = ""
+)
+dataSourceName := fmt.Sprintf("%s:%s@tcp(%s:%d)/%s", username, password, host, port, dbName)
+
+db, err := sql.Open("mysql", dataSourceName)
+if err != nil {
+    log.Fatal(err)
+}
+defer db.Close()
+```
+
+在 Gitpod 环境中，可以直接使用 run.sh 运行示例代码。
+
+```bash
+sh run.sh
+```
+
+### 使用 PreparedStatement
+
+使用 root 用户登录 OceanBase，运行如下命令：
+
+```bash
+alter system set _ob_enable_prepared_statement = true;
+```
