Since SQL Server Denali adds support for index compression of spatial indexes, using the same options as data and index compression in SQL Server 2008 and above. As opposed to what I expected at first (because spatial indexes consist of only a few small Read More...
After the last post on new warnings in SQL Server Denali Showplan , just for the fun of it, I had a look at the XML version of the showplan. And saw some fairly amazing new things I hadn't noticed before. Everyone's been looking into the new "Batch Read More...
Sort and hash warnings can be found using SQL Server profiler, but they don't appear in query plans like "Columns With No Statstics" warnings in SQL Server 2008 R2 and below. In SQL Server Denali, they DO appear in query plans. No profiler Read More...
Earlier this month I noticed that SQL Azure, with the latest upgrade has a version of 11...something (actually 11.0.1467.26, to be exact). And I wondered, aside from the long-touted new spatial library, if there were any Denali T-SQL enhancements that Read More...
With the release of SQL Server Denali approaching, (some Denali features are already available in SQL Azure Database ), I've decided its time to sift a few Denali features into my 5-day SQLskills Developer Skills Immersion Event on the week of October Read More...
The new Semantic Search feature of SQL Server Denali enhances full-text search by letting you do a search on the meaning of documents. To use this feature, its required that you install the SemanticsDB. The SemanticsDB ships with SQL Server or can be Read More...
I've been looking at full-text query plans in Denali lately, and looking at the SQL query plan for the full-text part, there isn't much to see (modulo docid lookup or lack of it, see a couple of posts ago ). Everything seemed to be hidden behind Read More...
I've been working lately with SQL Server Denali's Semantic Search feature. There's a more complete description of this feature (as well as how to set it up, its an addition to full-text indexing) in BOL, but I just wanted to summarize my one Read More...
SQL Server Denali's new Filetable feature and full-text search are made for each other. Set up database for non-transactional filestream access with a directory name, create a table "AS FILETABLE" with a subdirectory name, drag over a bunch Read More...
I've been trying this out every day or so since I'd heard about the update (originally named the July 2011 Service Release ), but I'd forgotten about it for about a week. So I don't exactly know when this happened on my SQL Azure server. Read More...
Once upon a time (well, now, currently), there were two memory allocators in SQL Server, the single-page allocator and the multi-page allocator. The single-page allocator was used for almost everything (data buffers, caches, etc); the multi-page allocator Read More...
I'm not usually one for repeating stuff you can find in BOL. Usually, a waste of your time and mine. But this feature, for SQL Server Denali, is pretty well buried; well at least from me, and I knew what I was looking for. I've always been interested Read More...
In the previous post , I insinuated that allowing LAG/LEAD to be sensitive to value RANGEs might help with series of data with missing values. It won't do that unless there's some logic that allows the offset that LAG/LEAD uses to be calculated Read More...
You've heard my rant before "measure what you think you are measuring". If not, follow the link . Here's an example using the LAG function, new in SQL Server Denali, to measure sales trends. We'll start with a view from AdventureWorksDW2008R2 Read More...
A (couple of days late) thanks to all the folks that attended my "What's New in Denali" demo fest at Portland SQL Server User Group last Thursday. I hope the code-based explanation of the "zen" of Columnstore Index, Semantic Search/Fulltext Read More...
