I have mentioned before about doing development for StreamInsight in Linqpad. I have it installed on two separate PCs and I have enabled autocompletion on only one of them. Whilst both versions are an excellent tool, the one with autocompletion enabled is so much easier to use. After enabling autocompletion you can see I now get parameter listing

Running Profiler traces against multiple servers becomes a painful process when it’s time to collate and filter all that data. It would be time-consuming, frustrating and messy if Laerte hadn’t written this handy PowerShell script (complete with examples) to help you out.

I am always conscious to keep a record of all operations performed on my database servers. Operations through T-SQL in an SSMS query pane can easily be saved in query files. For table modifications through SSMS designer I have predefined setting to generate T-SQL scripts. However there are numerous database and server level tasks that I use the SSMS GUI and I would like to have a script of these changes for later reference. Examples of such actions through the SSMS GUI are backup/restore, changing compatibility level of a database, manipulating permissions, dealing with database or log files or creating/manipulating any login/user. I am looking for any way to generate T-SQL code for such actions, so that it may be kept for later reference

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.

Changes are inevitable and like many other things in life your application will change over time. The question is how to upgrade an already deployed Data Tier Application to a newer version; what are the different methods available for upgrade and what considerations should you take?

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.

I have some data in a table:
CREATE TABLE #test_data
(
id INT PRIMARY KEY,
name VARCHAR(100),
birth_date DATE
);
-- Step 2: Insert rows
INSERT INTO #test_data
VALUES
(1, 'Olivia', '2025-01-05'),
(2, 'Emma', '2025-03-02'),
(3, 'Liam', '2025-11-15'),
(4, 'Noah', '2025-12-22');
If I run this query, how many rows are returned?
SELECT t1.[key] AS row,
t2.*
FROM OPENJSON(
(
SELECT t.* FROM #test_data AS t FOR JSON PATH
)
) t1
CROSS APPLY OPENJSON(t1.value) t2; See possible answers
