I recently got a table partitioning question from a reader:
We now need to load some historical data into the table for 2013 so I want to alter the function and schema to add monthly partitions for this. But I can’t work out how to do this using SPLIT? Every example and tutorial I’ve looked at shows how to add new partitions onto the end of a range, not split one in the middle.
This week’s ‘Dear SQL DBA’ question gets us down to the essentials: how to I tell if a transaction is hanging?
At the beginning of the “Troubleshooting Blocking and Deadlocks” course, I mention that it took me a long time to get into using the tools I show in the course.
The tools are all free, and many of them are built into SQL Server.
Update: the course itself is now free, too!
I made y’all a SQL Server style Valentine’s day present: a new FREE online training course.
This week’s question is about a longstanding feature in SQL Server that sounds really cool: full-text search. If you’re learning performance tuning, how much time should you invest in researching and learning about full-text indexes?
You’re designing table partitioning, or you want to make a change to an existing partition function. It’s critical to understand the difference between how “left” and “right” partition functions behave, but the documentation is a bit confusing on this topic.
I see HEAP tables are found even when I know those tables have a clustered index, and I see a lot of forwarded records. This happens to 5 tables in my database. I can see the clustered and in some ones the non-clustered indexes… why are some scripts reporting them as heaps?
