 ### <a id="create-an-item"></a>Create items using stored procedures
 
-When you create an item by using a stored procedure, the item is inserted into the Azure Cosmos DB 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. If a callback isn't provided and there's an error, the Azure Cosmos DB runtime throws an error.

 The stored procedure also includes a parameter to set the description as a boolean value. When the parameter is set to true and the description is missing, the stored procedure throws an exception. Otherwise, the rest of the stored procedure continues to run.
 
-The following example of a stored procedure takes an array of new Azure Cosmos DB items as input, inserts it into the Azure Cosmos DB container and returns the count of the items inserted. In this example, we're using the ToDoList sample from the [Quickstart .NET API for NoSQL](quickstart-dotnet.md).

 ### Arrays as input parameters for stored procedures
 
-When you define 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 a 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 DB 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.
