Find slow queriesTo establish that you have query performance issues on your SQL Server instance, start by examining queries by their execution time (elapsed time). Check if the time exceeds a threshold you have set (in milliseconds) based on an established performance baseline. For example, in...
Q What's the best way to terminate long-running queries launched from ASP.NET? The queries could be against the relational SQL databases or against online analytical processing (OLAP) cubes.A To begin, run the query on its own thread, asynchronously for example; then use the Cancel method ...
Can I find out the "Listener" name through a SQL Server Query Can i give a rollup an Alias? Can I have a conditional JOIN? Can I have a primary key as a non-unique column Can I pass parameter to an ALTER DATABASE command Can I prevent deadlock during concurrent delete Can I print...
the query is still hanging around too. To alleviate this, increase your fetch size to 500. Every query ran will come back with the first 500 rows, and rows will be continued to be fetched in 500 row increments. You’ll then see most of your ad hoc queries complete with a single ...

Web servers and services monitoring includes: Microsoft Internet Information Services (IIS) Admin, WWW Publishing, custom encryption application service, and specific Web sites.

queries and updates dealing with relatively small amounts of data. An example is an order entry system. For the rest of this paper, the termapplicationis generically used to refer to an OLTP application storing data in a SQL Server database, and the consolidation strategy applies primarily to...
of the full query text. In other words, the last portion of the full query text is what is currently running on the SQL Server instance. The formula below accounts for that. With all this being said, let's now look at the query and a sample of what to expect when reviewing results:...
You may find that this query tells you about SQL Server internal processes that started when the database booted and are running in the background. These use lots of total CPU time because they've been running for days at a time, but they have spent most of that time in an idle state...
Text-to-SQL (or Text2SQL), as the name implies, is to convert text into SQL. A more academic definition is to convert natural language problems in the database field into structured query languages that can be executed in relational databases. Therefore, Text-to-SQL can also be ab...
