+# 替换表
+
+在 0.14 版本中，Doris 支持对两个表进行原子的替换操作。
+该操作仅适用于 OLAP 表。
+
+分区级别的替换操作，请参阅 [临时分区文档](./alter-table-temp-partition.md)
+
+## 语法说明
+
+```
+ALTER TABLE [db.]tbl1 REPLACE WITH tbl2
+[PROPERTIES('swap' = 'true')];
+```
+
+将表 tbl1 替换为表 tbl2。
+
+如果 `swap` 参数为 `true`，则替换后，名称为 `tbl1` 表中的数据为原 `tbl2` 表中的数据。而名称为 `tbl2` 表中的数据为原
`tbl1` 表中的数据。即两张表数据发生了互换。
+
+如果 `swap` 参数为 `true`，则替换后，名称为 `tbl1` 表中的数据为原 `tbl2` 表中的数据。而名称为 `tbl2` 表被删除。
