 When updating the entire entity data, it is very easy to cause the old data to update the new record in the case of concurrency.
 
-乐观锁的原理，是利用实体某字段，如：long version，更新前先查询数据，此时 version 为 1，更新时产生的 SQL 会附加 where version = 1，当修改失败时（即 Affrows == 0）抛出异常（DbUpdateVersionException）。
+The principle of optimistic locking: use a certain field of the entity, such as `long version`. Query the data before updating, and then `version` is `1`. The SQL generated during the update will append `where version = 1`, and an exception (DbUpdateVersionException) will be thrown when the modification fails (ie, `Affrows == 0`).
 
-每个实体只支持一个乐观锁属性，在属性前标记特性：[Column(IsVersion = true)] 即可。
+Each entity only supports one optimistic lock attribute, mark the attribute before the property: `[Column(IsVersion = true)]`.
 
-> 适用 SetSource 更新，每次更新 version 的值都会增加 1
+> Applicable to SetSource update, the value of `version` will increase by `1` each time it is updated.

-for update 在 Oracle/PostgreSQL/MySql 是通用的写法，我们对 SqlServer 做了特别适配，执行的 SQL 语句大致如下：
+`ForUpdate` is a common way of writing in Oracle/PostgreSQL/MySql. We have made a special adaptation to SqlServer. The SQL statements executed are roughly as follows:
 
 ```sql
