存储过程azure Cosmos DB返回空集合 [英] Stored procedure azure Cosmos DB returns empty collection

问题描述

我尝试使用Azure文档中的示例sp创建代码创建存储过程，但我无法获取集合详细信息。它总是返回null。

I tried to create a stored procedure using the sample sp creation code from Azure docs, but i couldn't fetch the collection details. It always returns null.

// SAMPLE STORED PROCEDURE
function sample(prefix) {
    var collection = getContext().getCollection();
    console.log(JSON.stringify(collection));

    // Query documents and take 1st item.
    var isAccepted = collection.queryDocuments(
        collection.getSelfLink(),
        'SELECT * FROM root r',
    function (err, feed, options) {
        if (err) throw err;

        // Check the feed and if empty, set the body to 'no docs found', 
        // else take 1st element from feed
        if (!feed || !feed.length) {
            var response = getContext().getResponse();
            response.setBody('no docs found');
        }
        else {
            var response = getContext().getResponse();
            var body = { prefix: prefix, feed: feed[0] };
            response.setBody(JSON.stringify(body));
        }
    });

    if (!isAccepted) throw new Error('The query was not accepted by the server.');
}

控制台仅显示此信息。

The console shows only this.

结果显示没有找到文档，因为没有收集。我已经通过了分区键通过资源管理器执行。

the results shows no doc found because of not getting collection.I have passed the partition key at time of execution via explorer.

推荐答案

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.
