 ``` sql
 ALTER TABLE [db.]table [ON CLUSTER cluster] DELETE WHERE filter_expr
 ```
 
-Deletes data matching the specified filtering expression. Implemented as a [mutation](../../../sql-reference/statements/alter/index.md#mutations).
+删除匹配指定过滤表达式的数据。实现为[突变](../../../sql-reference/statements/alter/index.md#mutations).
 
-!!! note "Note"
-    The `ALTER TABLE` prefix makes this syntax different from most other systems supporting SQL. It is intended to signify that unlike similar queries in OLTP databases this is a heavy operation not designed for frequent use.
+!!! note "备注"
+    `ALTER TABLE`前缀使得这个语法不同于大多数其他支持SQL的系统。它的目的是表示，与OLTP数据库中的类似查询不同，这是一个不为经常使用而设计的繁重操作。
 
-The `filter_expr` must be of type `UInt8`. The query deletes rows in the table for which this expression takes a non-zero value.
+`filter_expr` 的类型必须是`UInt8`。该查询删除表中该表达式接受非零值的行。
 
-One query can contain several commands separated by commas.
+一个查询可以包含多个用逗号分隔的命令。
 
-The synchronicity of the query processing is defined by the [mutations_sync](../../../operations/settings/settings.md#mutations_sync) setting. By default, it is asynchronous.
+查询处理的同步性由[mutations_sync](../../../operations/settings/settings.md#mutations_sync)设置定义。缺省情况下，是异步的。
