检查表是否存在。

代码示例

C++

如需了解如何安装和使用 Bigtable 的客户端库，请参阅 Bigtable 客户端库。

如需向 Bigtable 进行身份验证，请设置应用默认凭据。 如需了解详情，请参阅为本地开发环境设置身份验证。

namespace cbt = ::google::cloud::bigtable;
namespace cbta = ::google::cloud::bigtable_admin;
using ::google::cloud::StatusOr;
[](cbta::BigtableTableAdminClient admin, std::string const& project_id,
   std::string const& instance_id, std::string const& table_id) {
  std::string table_name = cbt::TableName(project_id, instance_id, table_id);

  google::bigtable::admin::v2::GetTableRequest r;
  r.set_name(table_name);
  r.set_view(google::bigtable::admin::v2::Table::NAME_ONLY);

  StatusOr<google::bigtable::admin::v2::Table> table =
      admin.GetTable(std::move(r));
  if (!table) {
    if (table.status().code() == google::cloud::StatusCode::kNotFound) {
      std::cout << "Table " << table_id << " does not exist\n";
      return;
    }
    throw std::move(table).status();
  }

  std::cout << "Table " << table_id << " was found\n";
}
