您可以使用Java客户端API处理此代码片段以从BigQuery中删除记录：

import com.google.cloud.bigquery.BigQuery;
import com.google.cloud.bigquery.BigQueryOptions;
import com.google.cloud.bigquery.QueryJobConfiguration;
import com.google.cloud.bigquery.TableId;

public class DeleteRecords {
  public static void main(String[] args) throws InterruptedException {
    // TODO(developer): Replace these variables before running the sample.
    String projectId = "your-project-id";
    String datasetName = "my_dataset";
    String tableName = "my_table";
    String filterCondition = "somecondition";

    BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService();
    QueryJobConfiguration queryConfig =
        QueryJobConfiguration.newBuilder(
                String.format(
                    "DELETE FROM `%s.%s.%s` WHERE %s",
                    projectId, datasetName, tableName, filterCondition))
            .build();

    bigquery.query(queryConfig);
  }
}
