Question

我正在开发一个大数据规模的系统。目前，我正在使用少于300k的文档测试存储过程。

我关注这个例子： DocumentDB server-side programming: Stored procedures, database triggers, and UDFs

“createDocument”和“replaceDocument”到目前为止工作正常。但是无论我尝试了多少种方式，queryDocuments根本不起作用。我试图在很多地方抛出异常但是在callBack中抛出异常并没有被击中。

是否有人在存储过程中成功使用了queryDocuments（）？

function MoveTree(nodeJson, targetParentNodeJson) {
var node = JSON.parse(nodeJson);
var targetParentNode = JSON.parse(targetParentNodeJson);

var collection = getContext().getCollection();
var collectionLink = collection.getSelfLink();

var count = 0;

//<==Tried put throw exception here and it is hit
var node;
var IsAccept = collection.queryDocuments(
    collection.getSelfLink(),
    'SELECT * FROM Nodes p where p.id  = "' + nodeId + '"',
    function (err, documents, responseOptions) {
        //<==Tried put throw exception here but it is not hit
        if (err) throw new Error(err);
        if (!documents || documents.length != 1) throw new Error("Unable to find node.");
        node = documents[0];
        //<==Tried put throw exception here but it is not hit
    });
//<==Tried put throw exception here and it is hit

// ... }

正如Larry所提到的，问题是您没有设置nodeId变量...运行时会出现以下错误消息：

Encountered exception while executing Javascript. Exception = ReferenceError: 'nodeId' is undefined

DocumentDb存储procudure collection.queryDocuments不起作用
