如何在使用Java Bigquery API执行更新操作时检索更新的行数

import com.google.cloud.bigquery.BigQuery;
import com.google.cloud.bigquery.BigQueryOptions;
import com.google.cloud.bigquery.QueryJobConfiguration;
import com.google.cloud.bigquery.QueryResponse;
import com.google.cloud.bigquery.TableResult;

public class UpdateRowCountExample {
    public static void main(String[] args) throws Exception {
        // 创建BigQuery客户端对象
        BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService();

        // 设置更新操作的SQL语句
        String sql = "UPDATE `project.dataset.table` SET column1 = value1, column2 = value2 WHERE condition;";

        // 创建查询请求对象
        QueryJobConfiguration queryConfig = QueryJobConfiguration.newBuilder(sql).build();

        // 执行查询请求
        TableResult result = bigquery.query(queryConfig);

        // 获取查询结果对象
        QueryResponse response = result.getJob().getQueryResults();

        // 提取更新的行数
        long totalRows = response.getTotalRows();
        long updatedRows = response.getRows().size();

        System.out.println("总行数：" + totalRows);
        System.out.println("更新的行数：" + updatedRows);
    }
}
