For accessing to collection content I need to know {collection-name} and {document-key}.
How I can get list of all documents with their {document-key} in ArangoDB with http?
In docs there is a GET /_api/document request which will retrieve all documents from collection. If you specify type=key query string parameter then you will get response with an array of document keys.

I was making a commenting system on my website. I stored all the comment data in MongoDB and now I abviously need to access that data to print out the comments to a user. But, I see that there is no 'findMany' function for the collection object. I just need to get all the code in the collection in an array. findOne finds one document, then findMany should be there right? Is there any other such function in the collection object which can give me all the data in a collection of a database in MongoDB
Any help would be great!
You must use the find().toArray() method instead of findMany({ }) to get all the data there in the collection and to keep that data in an array. This will give you an array with all the data in the collection.
What is the difference between the two?
Subcollections store extra data inside a document as a collection and are not part of the document because they must be accessed as a separate call.
Mongodb sub documents store extra documents inside a document property as array and I'm not sure if the whole documents are retrieved in one document call.
Actually, what I'm asking is: How to achieve Subcollections in mongodb?
How to find particular json document details from couchdb
For ex : Database name : employee_mgmt, in that database contains 50 json documents. So i want to find particular employee json documents ( Find by employee id ).
CouchDB does in it self not provide you with collections/buckets, hence all your documents are peers. It's up to you to provide meta-data e.g. by having a property $doctype with a value representing what kind of document it is. This is useful if you are writing maps and e.g. want to create a view (secondary index) returning something applicable only to employees.
Know, if you just want to query by _id you don't need the above. Just do a simple GET with an URI as: http://host:port/databasename/documentid
More information: http://docs.couchdb.org/en/1.6.1/api/document/common.html#get--db-docid
If you want to get a batch of documents matching many _id use the builtin index _all_docs http://docs.couchdb.org/en/1.6.1/api/database/bulk-api.html#post--db-_all_docs
I'm playing with DocumentDB's client side javascript API. I want to be able to query a collection. I'd like to use a collection URL, something like:
"https://mydocumentdb.documents.azure.com:9443/dbs/my_db/colls/my_users"
but there appears to be no API function for me to query a documentdb collection without first having the database "self link" and then in turn getting the collections "self link". The only way to get these self links appears to be to first iterate through all my DB's and then pull the right self link, then iterate through my collections, get the collection, finally, use my self link that I got from the service to query the collection.
Really???
Not exactly.
You're correct in that you have to query for a collection's self-link prior to querying the collection. (I know... this can be quite annoying, and is being looked in to by the DocDB team).
However, there is no need to iterate through all of your DB/collections to retrieve self-links as they are indexed server-side.
It is better to query directly for the particular DB/collection you're looking for, which looks something like: client.queryCollections(database._self, 'SELECT * FROM collections c WHERE c.id="' + collectionId + '"'), where collectionId is an identifier you assign.
I want to get a list of documents which are in Shared Documents (this is the Document Library). I am using the GetListItems web service.
I am getting response with list of rows. But I don't see a word document which is created under that. Am I doing something wrong?
The GetListItems method does not return actual documents, it returns the ListItem information (metadata). It should include a Url (FileRef / FileLeafRef) property you can use to download the documents by looping through the method's result.
