 ## Sharding Tables and Database
 
-FreeSql 提供 AsTable 分表的基础方法，GuidRepository 作为分存式仓储将实现了分表与分库（不支持跨服务器分库）的封装。
+FreeSql provides a basic method of sharding tables through `AsTable`. As a distributed repository, and `GuidRepository` as a distributed storage, realizes the encapsulation of sharding tables and database (cross-server sharding-database is not supported).
 
 ```csharp
 var logRepository = fsql.GetGuidRepository<Log>(null, oldname => $"{oldname}_{DateTime.Now.ToString("YYYYMM")}");
 ```
 
-上面我们得到一个日志仓储按年月分表，使用它 CURD 最终会操作 Log_201903 表。
+Above we got a log repository, which corresponds to the shareding-table by year and month. Using CURD operation will finally take effect in the `Log_201903` table.
 
-注意事项：
+Notice:
 
-* v0.11.12以后的版本可以使用 CodeFirst 迁移分表；
-* 不可在分表分库的实体类型中使用《延时加载》；
+* Versions after v0.11.12 can use CodeFirst to migrate sharding tables.
+* Do not use lazy loading in the entity type of sharding tables and database.
 
 ## Compatibility Problems
 
-SqlServer 提供的 output inserted 特性，在表使用了自增或数据库定义了默认值的时候，使用它可以快速将 insert 的数据返回。PostgreSQL 也有相应的功能，如此方便但不是每个数据库都支持。
+The `output inserted` feature provided by SqlServer. When the table uses auto-increment or the database defines a default value, use this feature to quickly return the inserted data. PostgreSQL also has similar functions, but not every database supports it. 
 
-当采用了不支持该特性的数据库（Sqlite/MySql/Oracle/达梦/MsAccess），并且实体使用了自增属性，仓储批量插入将变为逐条执行，可以考虑以下改进：
+When a database that does not support this feature (Sqlite/MySql/Oracle/Damen/MsAccess) is used, and the entity uses auto-increment attributes, the batch insertion of the repository will be executed one by one. The following improvements can be considered:
 
-* 使用 uuid 作为主键（即 Guid）；
-* 避免使用数据库的默认值功能；
+* Use uuid as the primary key (ie Guid).
+* Avoid using the default value function of the database.
