表数据批量删除有实例代码吗？

在进行表数据批量删除操作时，可以使用阿里云表格存储的SDK来实现。以下是一个使用Java SDK进行批量删除的示例代码片段：

import com.alicloud.openservices.tablestore.SyncClient;
import com.alicloud.openservices.tablestore.model.BatchWriteRowRequest;
import com.alicloud.openservices.tablestore.model.BatchWriteRowResponse;
import com.alicloud.openservices.tablestore.model.PrimaryKeyBuilder;
import com.alicloud.openservices.tablestore.model.RowDeleteChange;
import com.alicloud.openservices.tablestore.model.TableStoreException;

public class BatchDeleteExample {
    public static void main(String[] args) {
        // 初始化SyncClient实例（请替换为您的实际AccessKey ID、AccessKey Secret、Endpoint和实例名）
        SyncClient client = new SyncClient("<your-access-key-id>", "<your-access-key-secret>", "<your-endpoint>", "<your-instance-name>");

        try {
            // 创建BatchWriteRowRequest对象
            BatchWriteRowRequest batchWriteRowRequest = new BatchWriteRowRequest();

            // 构造要删除的第一行的主键信息
            PrimaryKeyBuilder pk1Builder = PrimaryKeyBuilder.createPrimaryKeyBuilder();
            pk1Builder.addPrimaryKeyColumn("pk1", PrimaryKeyValue.fromString("value1"));
            pk1Builder.addPrimaryKeyColumn("pk2", PrimaryKeyValue.fromLong(123));
            RowDeleteChange rowDeleteChange1 = new RowDeleteChange("<YOUR_TABLE_NAME>", pk1Builder.build());
            batchWriteRowRequest.addRowChange(rowDeleteChange1);

            // 构造要删除的第二行的主键信息，以此类推...
            // 注意：根据实际需求添加更多行的删除操作

            // 执行批量删除操作
            BatchWriteRowResponse response = client.batchWriteRow(batchWriteRowRequest);

            System.out.println("是否全部成功：" + response.isAllSucceed());
            if (!response.isAllSucceed()) {
                for (BatchWriteRowResponse.RowResult rowResult : response.getFailedRows()) {
                    System.out.println("失败的行：" + batchWriteRowRequest.getRowChange(rowResult.getTableName(), rowResult.getIndex()).getPrimaryKey());
                    System.out.println("失败原因：" + rowResult.getError());
                }
                // 可以根据需要处理失败的行，例如重试
            }
        } catch (TableStoreException e) {
            // 处理异常情况
            e.printStackTrace();
        } finally {
            // 关闭client连接
            client.shutdown();
        }
    }
}

请确保替换上述代码中的<your-access-key-id>、<your-access-key-secret>、<your-endpoint>、<your-instance-name>以及<YOUR_TABLE_NAME>和具体的主键值，以匹配您的实际环境配置。

此代码示例展示了如何通过构建BatchWriteRowRequest，向指定的表中添加多个RowDeleteChange来实现数据的批量删除，并且包含了错误处理逻辑，以便于理解和应用到实际项目中。
