Code the Processing Stored Procedure

Step 1 - Add a StoredProcedureSpec to the catalog project and provide the following code

In this stored procedure, we accept in an a string representing an XML document of the time zone data to process. We place the XML into a table variable named @TIMEZONEXMLTABLE and use the data within a T-SQL MERGE statement whereby we UPDATE a row when the incoming ADDRESSCOORDINATESID value matches or INSERT a row when no match occurs. Place a summary of actions into a table variable named @SummaryOfChanges. Provide a count of the inserts and updates back to the client (CLR code).

Step 2 - Load the SQLStoredProcedureSpec

Review the completed SQLStoredProcedureSpec below and load into the database via LoadSpec.
