+以 [example.rb](example.rb) 为例。
+
+```
+require 'sequel'
+
+# 连接到OceanBase数据库
+DB = Sequel.connect(
+  adapter:  'mysql2',
+  host:     '127.0.0.1',
+  port:     2881,
+  user:     'root',
+  password: '',
+  database: 'test'
+)
+
+if DB.test_connection
+  puts "成功连接到OceanBase数据库"
+else
+  puts "连接到OceanBase数据库失败"
+end
+
