删除单行数据

前提条件

初始化Tablestore Client

方法说明

public DeleteRowResponse deleteRow(DeleteRowRequest deleteRowRequest) throws TableStoreException, ClientException

示例代码

以下示例代码用于删除 test_table 表中主键值为 row1 的行数据。

public static void deleteRowExample(SyncClient client) {
    // 构造主键
    PrimaryKeyBuilder primaryKeyBuilder = PrimaryKeyBuilder.createPrimaryKeyBuilder();
    primaryKeyBuilder.addPrimaryKeyColumn("id", PrimaryKeyValue.fromString("row1"));
    PrimaryKey primaryKey = primaryKeyBuilder.build();

    // 构造删除的行数据
    RowDeleteChange rowDeleteChange = new RowDeleteChange("test_table", primaryKey);

    // 调用 deleteRow 方法删除行数据
    DeleteRowRequest deleteRowRequest = new DeleteRowRequest(rowDeleteChange);
    DeleteRowResponse deleteRowResponse = client.deleteRow(deleteRowRequest);

    // 返回结果处理
    System.out.println("RequestId: " + deleteRowResponse.getRequestId());
    System.out.println("Read CU Cost: " + deleteRowResponse.getConsumedCapacity().getCapacityUnit().getReadCapacityUnit());
    System.out.println("Write CU Cost: " + deleteRowResponse.getConsumedCapacity().getCapacityUnit().getWriteCapacityUnit());
}
