I had a very interesting conversation with one of my clients about Cardinality Estimation for Temp Table vs Table Variable. Let us discuss it today.
When SQL Server uses TempDB when any query does not have enough memory to do its operation, it is called TempDB Spill. Let’s learn today.
Today we are going to discuss the performance comparison of table variables and temp tables when we are running SELECT queries.
Question: Where is Table Variable Created?
Answer: On Hard Disk and NOT in Memory.

After the blog posts about temp and regular table, I have received questions about it hence I am writing this blog post about TempDB Logging.
This was a very interesting situation and at the end of we had found the culprit for the slow query and resolved it. Today we will discuss the experience.
