North Haven – SQL Saturday #268

I am totally pumped up about having the opportunity to present at SQL Saturday #268 in North Haven.

It will be a good time to meet old friends and make new ones. I hope you have time to attend cool event on March 1st, 2014!


Effective use of temporary tables


Every developer eventually comes against business logic that can’t be handled with a single simple or complex query. TSQL provides the developer with several constructs that can store temporary result sets that are passed to the next query in the script.

I will be covering these various TSQL techniques with examples using the [AdventureWorks] database as well as a toy database called AUTOS. The pros and cons of each construct will be examined. Advanced options like enabling trace flag 1118 will be explored.


1 – Derived tables.
2 – Local temporary tables.
3 – Global temporary tables.
4 – Table variables.
5 – Common Table Expressions (CTE).
6 – User databases in [tempdb].
7 – Trace Flag 1118.

Here is a previous slide deck. I will update later for this event.
