Stored procedures Cosmos DB:getContext（）.getCollection（）.queryDocuments不返回SP中的项

我刚开始使用Cosmos DB，我很困惑为什么我不能使用简单的SP查询返回任何文档

这就是我所做的：

• 已使用分区键“/id”创建Cosmos DB数据库
• 创建“系列”目录
• 创建了两个项目：

• 运行查询“SELECT*FROM c”将按预期返回两条记录
• 但是，bellow SP中的queryDocuments方法总是为提要检索零长度。为什么两件东西都没有退回

非常感谢你的帮助

Cosmos db中的SP基于分区密钥工作，这意味着将返回分区内的所有文档，而不是跨分区的文档。您可以按照下面的屏幕截图执行SP。根据官方文档“对于分区容器，在执行存储过程时，必须在请求选项中提供分区键值。存储过程的作用域始终为分区键值。具有不同分区键值的项对存储过程不可见。这也适用于触发器。”

存储过程的作用域始终是分区键。您应该提供分区键值，如：'AndersenFamily'。您可以参考这个。谢谢，@SteveZhao！这就解释了！谢谢你，@AnuragSharma MSFT，这就解释了！
