Metode

public DeleteRowResponse deleteRow(DeleteRowRequest deleteRowRequest) throws TableStoreException, ClientException

Kode contoh

Contoh berikut menghapus baris dengan nilai kunci primer row1 dari tabel test_table.

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

    // Buat data baris yang akan dihapus.
    RowDeleteChange rowDeleteChange = new RowDeleteChange("test_table", primaryKey);

    // Panggil metode deleteRow untuk menghapus data baris.
    DeleteRowRequest deleteRowRequest = new DeleteRowRequest(rowDeleteChange);
    DeleteRowResponse deleteRowResponse = client.deleteRow(deleteRowRequest);

    // Tampilkan hasilnya.
    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());
}
