We have upgraded to the 2016 Service Pack 1 version of SQL Server. Microsoft are keeping the server based and Azure based versions much more in synch than they used to so it was no surprise to find a new feature in regular MS SQL available in Azure too.
When creating stored procedures in t-sql, it used to be necessary to change CREATE to Alter after first running in the script. Either than, or dropping the procedure first.
Now you can write the code like this:
CREATE OR ALTER spMyStoredProcedure
Maybe its not a headline grabbing change, but it does add efficiency in a simple way.
