我有类似的问题。我认为当分区键不一个字符串时，Azure门户不会正确执行存储过程。

I had a similar issue. I think the Azure portal doesn't execute stored procedures properly when the partition key is not a string.

在我的情况下，我有一个partitionKey这是一个数字。当我通过门户网站执行存储过程时，我总是得到一个空的resultSet，即使我的数据库中有文档。当我稍微更改结构，并使我的partitionKey成为一个字符串时，存储过程工作正常。

In my case I had a partitionKey that is a number. When I executed the stored procedure via the portal I always got an empty resultSet, even though I had documents in my database. When I changed the structure a little, and made my partitionKey a string, the stored procedure worked fine.
