Many times we want to split a string into an array and get a list of each word separately. The sys.dm_fts_parser function will help us in these cases. More over, this function will also differentiate the noise words and exact match words. The sys.dm_fts_parser can be also very powerful for debugging purposes. It can help you check how the word breaker and stemmer works for a given input for Full Text Search.

Slightly before the announcement of StreamInsight being available for Linqpad I downloaded it from here. I had seen Roman Schindlauer demonstrate it at Teched and it looked a really good tool to do some StreamInsight dev. You will need .Net 4.0 and StreamInsight installed.

Of the big four DML statements in SQL Server, the DELETE is the one least written about. This is odd considering the extra power conferred on the statement by the addition of the WITH common_table_expression; and the OUTPUT clause that essentially allows you to move data from one table to another in one statement.

Data warehousing and general reporting applications tend to be CPU intensive because they need to read and process a large number of rows. To facilitate quick data processing for queries that touch a large amount of data, Microsoft SQL Server exploits the power of multiple logical processors to provide parallel query processing operations such as parallel scans. Through extensive testing, we have learned that, for most large queries that are executed in a parallel fashion, SQL Server can deliver linear or nearly linear response time speedup as the number of logical processors increases. However, some queries in high parallelism scenarios perform suboptimally. There are also some parallelism issues that can occur in a multi-user parallel query workload. This white paper describes parallel performance problems you might encounter when you run such queries and workloads, and it explains why these issues occur. In addition, it presents how data warehouse developers can detect these issues, and how they can work around them or mitigate them.
