+## cl.data.relationalStore修改setDistributedTables接口入参type类型由number变为DistributedType
+
+**变更影响**
+
+基于OpenHarmony4.0.9.3及之后的SDK版本开发的应用，setDistributedTables接口入参type类型由number变为DistributedType。
+
+**关键接口/组件变更**
+
+1.修改前setDistributedTables接口：
+
+ ```ts
+setDistributedTables(tables: Array<string>, type: number, config: DistributedConfig, callback: AsyncCallback<void>): void;
+ ```
+
+修改后setDistributedTables接口：
+
+ ```ts
+setDistributedTables(tables: Array<string>, type: DistributedType, config: DistributedConfig, callback: AsyncCallback<void>): void;
+ ```
+
+2.修改前setDistributedTables接口：
+
+ ```ts
+setDistributedTables(tables: Array<string>, type?: number, config?: DistributedConfig): Promise<void>;
+ ```
+
+修改后setDistributedTables接口：
+
+ ```ts
+setDistributedTables(tables: Array<string>, type?: DistributedType, config?: DistributedConfig): Promise<void>;
+ ```
+
+## cl.data.relationalStore接口新增
+
+新增setDistributedTables(tables: Array&lt;string&gt;, type: DistributedType, callback: AsyncCallback&lt;void&gt; ): void接口。
+
+**变更影响**
+
+基于OpenHarmony4.0.9.3及之后的SDK版本开发的应用，可使用setDistributedTables(tables: Array&lt;string&gt;, type: DistributedType, callback: AsyncCallback&lt;void&gt; ): void设置分布式表。
+
+**关键接口/组件变更**
+
+@ohos.data.relationalStore.d.ts中新增setDistributedTables接口。
+
+| 模块名                          | 类名     | 方法/属性/枚举/常量                                          | 变更类型 |
+| ------------------------------- | -------- | ------------------------------------------------------------ | -------- |
+| @ohos.data.relationalStore.d.ts | RdbStore | setDistributedTables(tables: Array&lt;string&gt;, type: DistributedType, callback: AsyncCallback&lt;void&gt; ): void | 新增     |
+
+**适配指导**<br>
+
+通过调用setDistributedTables接口设置分布式表。
+
+```ts
+store.setDistributedTables(["EMPLOYEE"], relationalStore.DistributedType.DISTRIBUTED_CLOUD, function (err) {
+  if (err) {
+    console.error(`SetDistributedTables failed, code is ${err.code},message is ${err.message}`);
+    return;
+  }
+  console.info(`SetDistributedTables successfully.`);
+})
+```
+
