Database class

  • 参考
包:
@azure/cosmos

读取或删除现有数据库的作。

请参阅 数据库，了解如何创建新数据库，以及读取/查询所有数据库;使用 client.databases。

注意：所有这些作都针对固定预算进行调用。 应设计系统，以便这些调用与应用程序进行子线性缩放。 例如，在每次调用 database.read() 之前不要调用 item.read()，以确保数据库存在;在应用程序启动时执行此作。

属性

client
containers

用于创建新容器或查询/读取所有容器。

使用 .database(id) 按 ID 读取、替换或删除特定的现有 数据库。

示例

创建新容器

  .database("<db id>")
  .containers.create({ id: "<container id>" });
id
url
