Question

在针对Azure Cosmos DB非分区集合运行的存储过程中，我在选择查询下运行：

var twentyMinutesBefore = new Date();
twentyMinutesBefore.setMinutes(twentyMinutesBefore.getMinutes() - 20);
var filterQuery = "SELECT TOP 40 * FROM c WHERE (c.transmissionState = 2 AND (" + twentyMinutesBefore + " > c.dateCreated.epoch)) OR c.transmissionState = 0 ORDER BY c.dateCreated.epoch DESC";

我按如下方式执行查询：

var isAccepted = collection.queryDocuments(collectionLink, filterQuery, options, callback);

function callback(err, queryFeed, responseOptions) {
    if (err) {
        throw err; // <-- Error thrown from this line as per stack trace
    }
    // Iterate through query feed
}

我收到以下错误：

    "Message": "Microsoft.Azure.Documents.DocumentClientException: Message: 
{\"Errors\":[\"Encountered exception while executing function. Exception = Error:
{\\"errors\\":[{\\"severity\\":\\"Error\\",\\"location\\":{\\"start\\":63,\\"end\\":66},\\"code\\":\\"SC1001\\",
\\"message\\":\\"Syntax error, incorrect syntax near 'Dec'.\\"}]}   
    Stack trace: Error: {\\"errors\\":[{\\"severity\\":\\"Error\\",\\"location\\":{\\"start\\":63,\\"end\\":66},\\"code\\":\\"SC1001\\",\\"message\\":\\"Syntax error, incorrect syntax near 'Dec'.\\"}]}

在控制台应用程序中，我尝试解析过滤器查询以验证其格式是否正确。结果如下：

SELECT TOP 40 * FROM c WHERE (c.transmissionState = 2 AND (1512593297244 > c.dateCreated.epoch)) OR c.transmissionState = 0 ORDER BY c.dateCreated.epoch DESC

当我按原样复制此查询并在Cosmos DB查询窗口中运行时，它运行正常并按预期返回结果。

不确定为什么它不会通过存储过程运行。知道'Dec'在错误中意味着什么吗？我的存储过程中没有找到任何这样的字符串。

使用twentyMinutesBefore.getTime()，无getTime()获取UNIX纪元时间，您将获得完整日期，例如＆＃34; Thu Dec 07 2017 13:26:39 GMT+1100 (AUS Eastern Daylight Time)＆＃34;：

var filterQuery = "SELECT TOP 40 * FROM c WHERE (c.transmissionState = 2 AND (" + twentyMinutesBefore.getTime() + " > c.dateCreated.epoch)) OR c.transmissionState = 0 ORDER BY c.dateCreated.epoch DESC";

Azure Cosmos DB：通过存储过程执行查询时，“Dec”错误附近的语法不正确
