-The merging logic of table features can be controlled with `like options`.
+表属性的合并逻辑可以用 `like options` 来控制。
-You can control the merging behavior of:
+可以控制合并的表属性如下：
-* CONSTRAINTS - constraints such as primary and unique keys
-* GENERATED - computed columns
-* OPTIONS - connector options that describe connector and format properties
-* PARTITIONS - partition of the tables
-* WATERMARKS - watermark declarations
+* CONSTRAINTS - 主键和唯一键约束
+* GENERATED - 计算列
+* OPTIONS - 连接器信息、格式化方式等配置项
+* PARTITIONS - 表分区信息
+* WATERMARKS - watermark 定义
-with three different merging strategies:
+并且有三种不同的表属性合并策略：
-* INCLUDING - Includes the feature of the source table, fails on duplicate
entries, e.g. if an option with the same key exists in both tables.
-* EXCLUDING - Does not include the given feature of the source table.
-* OVERWRITING - Includes the feature of the source table, overwrites duplicate
entries of the source table with properties of the new table, e.g. if an option
with the same key exists in both tables, the one from the current statement
will be used.
+* INCLUDING - 新表包含源表（source table）所有的表属性，如果和源表的表属性重复则会直接失败，例如新表和源表存在相同 key 的属性。
+* EXCLUDING - 新表不包含源表指定的任何表属性。
+* OVERWRITING - 新表包含源表的表属性，但如果出现重复项，则会用新表的表属性覆盖源表中的重复表属性，例如，两个表中都存在相同 key
的属性，则会使用当前语句中定义的 key 的属性值。
-Additionally, you can use the `INCLUDING/EXCLUDING ALL` option to specify what
should be the strategy if there was no specific strategy defined, i.e. if you
use `EXCLUDING ALL INCLUDING WATERMARKS` only the watermarks will be included
from the source table.
+并且你可以使用 `INCLUDING/EXCLUDING ALL` 这种声明方式来指定使用怎样的合并策略，例如使用 `EXCLUDING ALL
INCLUDING WATERMARKS`，那么代表只有源表的 WATERMARKS 属性才会被包含进新表。
-Example:
+示例如下：
{% highlight sql %}
--- A source table stored in a filesystem
+
+-- 存储在文件系统的源表
CREATE TABLE Orders_in_file (
user BIGINT,
product STRING,
order_time_string STRING,
order_time AS to_timestamp(order_time)
