 由此可以看出, 除了对 表 模型的绑定区别, 其他方法通用
 
 ## 配置
 单数据库连接, 可以直接同官方接口一样用法
 ```go
-var gr = gorose.Open("mysql", "root:123456@tcp(localhost:3306)/test?charset=utf8mb4&parseTime=true")
+var rose = gorose.Open("mysql", "root:123456@tcp(localhost:3306)/test?charset=utf8mb4&parseTime=true")
 ```
 也可以用

 或者使用读写分离集群,事务内,自动强制从写库读数据
