Generating SQL With Biml

Cathrine Wilhelmsen shows us you can do a lot more with Biml than just generating SSIS packages:

This actually happened to me in a previous job. We had a fairly complex ETL solution for the most critical part of our Data Warehouse. Many SSIS packages, views, and stored procedures queried the tables that were replicas of the source system tables. One day, we found out that the source system would be deploying a new version of their database the following day. In every single table, some columns were removed, others added, and many changed data types.
Oh.
There was no way that we could manually update all our SSIS packages, views, and stored procedures in less than a day. Thousands of users depended on our solution. It was too late to pause the source system changes.
Oh.

That story ends up with a happy ending.
