Querying CosmosDB. Part 1

Hi CosmosDB Community !!!

I'd like to contribute with some posts about how to query Cosmos DB Collection with SQL API.

Suppose we have a speaker list of differents events around a whole world.

The link above represent speaker list example.
Example1.json

For all examples we will use Data Explore in Azure Portal. Anyway, you can use any API in any supported programming language to write your queries. We are not using Modeling data techniques or witting same data in different ways to avoid cross partition queries. The main objective of the post is how to use built-in functions and operators in CosmosDB SQL API.

I'd like to list all events from Hassan Arteaga Rodríguez

Query

SELECT * FROM c where c.speaker = "Hassan Arteaga Rodriguez"

Results

I need to list all events from MEXICO. Not all fields

Query

SELECT c.speaker, c.event_name,c.init_date,c.end_date FROM c where c.event_country = "MEXICO"

Results

I'd like to list all events in June

Query

SELECT * FROM c where c.init_date >= 20180601 and c.end_date<=20180630

Results

List all speakers and activities from event

Query

SELECT c.speaker, c.activities FROM c where c.event_name="CosmosDB Conf"

Results

Update data in COSMOS DB with Azure Functions.

I was looking for a way to update COSMOS DB document after receive a request inside Azure Function without any COSMOS DB biding. I didn't find a way !! I took another way. I don't know if it is the right or wrong way. But this way works for me. Scenario is very simple. We have sales orders arriving into the data base. We have another Azure function to insert those new orders. But suppose we need to cancel some order. How to do that using Azure Function ? Let´s start !!! Step 1. Sample Collection. This collection is very simple, we are focused on results. Step 2. Create a Function and Select HttpTrigger template. Step 3. Code More code. Step 4. Test Step 5. Results See you soon

Add more security to an Azure CosmosDB Account.

W e can access programmatically to Azure Cosmos DB resources to create, query, and delete databases, document collections, and documents via REST API. To perform operations on Azure Cosmos DB resources, you can send HTTPS requests with a selected method: GET, POST, PUT, or DELETE to an CosmosDB endpoint. Frequently we build architecture with centralized access to a persistence layer, then we won't let other applications access directly to this layer. Suppose we have the following hypothetical scenario (see Figure 1): Figure 1. Hypothetical Scenario Only WEB API Service with IP1 is allowed to establish connections with CosmosDB EndPoint. The others elements showed as Application are not allowed. By default we have in our CosmosDB resource the following configuration (see Figure 2) in Firewall and Virtual Networks option. Figure 2. Default Configuration To show you how this feature works, we are going to create a WEP API with a single function (r...

Querying CosmosDB. Part 2

Hi!!! We will continue to play a little with the same JSON Example in Part 1 We will try to do queries a little more complicated. Total amount of time (in minutes) of laboratory in particular event. Query SELECT VALUE SUM(act.duration) FROM c JOIN act IN c.activities WHERE act.type=”lab” AND c.event_name= “CosmosDB Conf” Results List activities from specific type and from specific event Query SELECT VALUE act FROM c JOIN act IN c.activities WHERE act.type=”conference” AND c.event_name= “CosmosDB Conf” Results Get activities where duration is more than 30 minutes Query SELECT VALUE act FROM c JOIN act IN c.activities WHERE act.duration>30 Results Same as previous but bring me more information for each document Query SELECT VALUE { “id”:c.id, “event”:c.event_name, “speaker”:c.speaker, “country”:c.event_country, “activity”:act} FROM c JOIN act IN c.activities WHERE act.duration>30 and act.type=”lab” Results In case...
