Maybe with good reason. But most likely not really. Wherever you look, you find tools and resources to help you migrate from something that is not Cosmos DB, to Cosmos DB. The Cosmos DB migration utility tool can only export a JSON file at most, but that can rarely be good enough if you need to move around more than a handful of documents. Assume that you decided to move your data out of Cosmos DB.

I recently had such a use case for a client.

Execute SQL Server Stored Procedure With User Parameter In Power BI

They figured out that they would benefit from it both in terms of costs as well as performance in their particular scenario. So… You guessed it… I decided to make one on my own. There were a few quirks to work out, such as how to stream a lot of data from Cosmos DB without it timing out, or how to efficiently insert a bulk of data into SQL Server. Eventually, I got it working.

Well… Roughly. The app has a configuration file to let you easily configure a bunch of important stuff, such as connection details to your source and destination, and a few other settings. That could be either a database table receiving a Bulk Copy stream, or a stored procedure receiving a table valued parameter again, configurable.

Fill in the required fields and in command window use the below line to execute the procedure. Replace the existing query with a new query. The below screenshot shows a comparison of both the queries. Select Query and enter the start date and end date. It will show a warning like this. It will show a warning to run the query in Native Mode. It will load all the data. Our data has been added to a Model. Try this on your own and share your opinion with me.

I got the same problem with you about the Failed to save the stored procedure. What I did to solve that problem is:. If you want to test this function on Azure Portal, you can delete the parameter "prefix" and add a variable name "prefix" to your stored procedure. The reason of this error is this function needs data from outside via parameterand you don't provide it on Azure Portal.

Here is what I observed: Saving worked, despite an error message. So this approach did not solve the problem of executing the Stored Procedure.

This approach does not seem to work. Can you "Save" the script only? If you still cannot run it, tell me. I tested it again with your code, this is the result: While the Failed to save the stored procedure error message still appeared, the script was actually saved.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

They will be needed for more complex DocumentDB operations that can't be handled in a single query or update. You may use the supported DocumentClient binding. Am I missing something, or perhaps looking in the wrong spot? I've asked the DocDB team to verify. We'll give you the client and you can use that to execute stored procedures directly using the API.

We'll keep this open and discuss how we could design this. Sproc management is already available to us in the Azure Portal in the feature called "Script Explorer". Executing the sproc is as simple as passing in zero or more parameters in a JSON array, and then receiving the text output document.

Is using DocumentClient still the correct way to call a stored procedure? Or is there a stored procedure binding planned? Using DocumentClient is still the way to do this. There's no planned sproc binding, although I think it's possible. If CosmosDB SQL was to have better support throughout Azure and much better documentation then adoption would probably increase by an order of magnitude.

We've been using it for a few years and are relatively happy, but I have spoken to several other developers who tried it and gave up, moving to the Mongo API to get the rich query engine or Table Storage to get the simplicity, or bah!

To run a store procedure I need to provide partition key ans I am not sure what value should I provide in this case?

Please assist. If the collection the stored procedure is registered against is a single-partition collection, then the transaction is scoped to all the documents within the collection. If the collection is partitioned, then stored procedures are executed in the transaction scope of a single partition key. Each stored procedure execution must then include a partition key value corresponding to the scope the transaction must run under.

You could refer to the description above which mentioned here. Based on your situationcity may be more appropriate. You may need to adjust your database partitioning scheme because the partitioning key can not be deleted or modified after you have defined it. I suggest you exporting your data to json file then import to a new collection which is partitioned by city via Azure Cosmos DB Data migration tool.

Just for summary: Issue: Unable to provide specific partition key value when executing sql to query documents.It is easy to apply and it makes database access super simple.

However, sometimes working with tables and views is just not enough. It is just a few lines of code and it works perfectly!

It also shows how we can pass a parameter to SQL, but you also can format it with curly braces. A stored procedure is a perfect example of a SQL, that you might want to run directly on the database, but keep SQL on the database side. If you would just like to execute it, you could simply have a code like this:.

While running a stored procedure or a plain SQL command can be done directly on the database level, returning the result is slightly more complicated. First of all, you need to add a keyless model to map your results. You can execute SQL on a database level, but when you care about the result, you need to add a DbSet representing your results. All code mentioned here can be found on my GitHubfeel free to experiment with it. Passing an interpolated string to FromSqlRaw is a really bad idea… it will format the value directly into the SQL command, which makes the app vulnerable to SQL injection.

If you use FromSqlInterpolated instead, the value will be passed as a parameter. MS also advises to use it, great feedback Thomas! Your email address will not be published.

Home ASP.Azure Cosmos DB provides language-integrated, transactional execution of JavaScript that lets you write stored procedurestriggersand user-defined functions UDFs.

You can write your logic in JavaScript and execute it inside the database engine. To call a stored procedure, trigger, and user-defined function, you need to register it. For more information, see How to work with stored procedures, triggers, user-defined functions in Azure Cosmos DB. For partitioned containers, when executing a stored procedure, a partition key value must be provided in the request options. Stored procedures are always scoped to a partition key.

Items that have a different partition key value will not be visible to the stored procedure. This also applied to triggers as well. Cosmos supports deploying containers with stored procedures, triggers and user-defined functions. Stored procedures are written using JavaScript, they can create, update, read, query, and delete items inside an Azure Cosmos container.

Stored procedures are registered per collection, and can operate on any document or an attachment present in that collection.

Migrating from CosmosDB to SQL Server

The context object provides access to all operations that can be performed in Azure Cosmos DB, as well as access to the request and response objects. In this case, you use the response object to set the body of the response to be sent back to the client. Once written, the stored procedure must be registered with a collection. When you create an item by using stored procedure, the item is inserted into the Azure Cosmos container and an ID for the newly created item is returned.

Creating an item is an asynchronous operation and depends on the JavaScript callback functions. The callback function has two parameters - one for the error object in case the operation fails and another for a return value; in this case, the created object. Inside the callback, you can either handle the exception or throw an error. In case a callback is not provided and there is an error, the Azure Cosmos DB runtime will throw an error.

The stored procedure also includes a parameter to set the description, it's a boolean value. When the parameter is set to true and the description is missing, the stored procedure will throw an exception.

Otherwise, the rest of the stored procedure continues to run. The following example stored procedure takes an array of new Azure Cosmos items as input, inserts it into the Azure Cosmos container and returns the count of the items inserted.

In this example, we are leveraging the ToDoList sample from the Quickstart. When defining a stored procedure in Azure portal, input parameters are always sent as a string to the stored procedure.

Even if you pass an array of strings as an input, the array is converted to string and sent to the stored procedure. To work around this, you can define a function within your stored procedure to parse the string as an array.

The following code shows how to parse a string input parameter as an array:. You can implement transactions on items within a container by using a stored procedure.

The following example uses transactions within a fantasy football gaming app to trade players between two teams in a single operation. The stored procedure attempts to read the two Azure Cosmos items each corresponding to the player IDs passed in as an argument. If both players are found, then the stored procedure updates the items by swapping their teams. If any errors are encountered along the way, the stored procedure throws a JavaScript exception that implicitly aborts the transaction.

The following is an example of a stored procedure that bulk-imports items into an Azure Cosmos container. The stored procedure handles bounded execution by checking the boolean return value from createDocumentand then uses the count of items inserted in each invocation of the stored procedure to track and resume progress across batches. The following is an example of a stored procedure that uses async-await with Promises using a helper function. The stored procedure queries for an item and replaces it.

Azure Cosmos DB supports pre-triggers and post-triggers. Pre-triggers are executed before modifying a database item and post-triggers are executed after modifying a database item.
