At the end of Stairway Level 12 you wrote this...
The next Transact-SQL Stairway will cover more advanced topics. I will be discussing additional T-SQL functionality that will allow you round out your T-SQL programming skills. Here is a partial list of topics that will I be covering:
IF THEN ELSE logic
User Defined Functions
Use of Temporary Table
Common Table Expressions (CTEs).
Where can I go to get a more in depth view of these more advanced topics? Is there other stairways for these? I have been looking all over the site and cannot find where they might be.
Hope you can help with my query
