Querying remote data sources in SQL Server June 10, 2016 by Ahmad Yaseen A common activity when writing T-SQL queries is connecting to local databases and processing data directly. But there will be situations in which you need to connect to a remote database that is located in a different instance in the same server or in a different physical server, and process its data in parallel with the local data processing. SQL Server provides us with four useful methods to connect to the remote database servers, even other database server types, and query its data within your T-SQL statement. In this article, we will discuss these four methods and how to use it to query remote SQL Server databases. Read more »
Troubleshooting the CXPACKET wait type in SQL Server June 8, 2016 by Nikola Dimitrijevic The SQL Server CXPACKET wait type is one of the most misinterpreted wait stats.

Useful DBCC log commands June 1, 2016 by Timothy Smith Background When we’re architecting or troubleshooting issues in an environment, understanding how the log is set up and its history helps us identify if improving it will carry significant impacts overall. We have some built in tools that we can use, such as DBCC LOGINFO and DBCC SQLPERF and in this tip we look at how we can use them when we’re debugging issues, designing our logs for scale, or monitoring our current setup. We also look at some ways we can retain the information these provide so that we can use this for historic measurements and benchmarking, as well as using them for potentially alerting. Read more »
SQL Server 2014 contained databases June 1, 2016 by Ahmad Yaseen SQL Server provides two ways to authenticate users; SQL Server Authentication, which requires a predefined username and password to connect to the SQL Server, and Windows Authentication, in which SQL Server trusts the windows integrated user. The server level user that is authenticated to connect to the SQL Server is called a Server Login. This login should be mapped to a database user and granted permissions at the database level in order to access the database and be able to perform the authorized tasks. The relationship between the Server login and the database user in addition to the database metadata stored in the master system database draw up the dependencies between the SQL Server databases the server-level resources.

Monitoring changes in SQL Server using change data capture May 27, 2016 by Timothy Smith Background In multi-user environments, changes may occur frequently to the architecture, data, or overall structure that creates work for other users. In this series, we look at some ways that we can track changes on the data and architecture layer for pin-pointing times, changes, and using the information for alerting, if changes should be kept to a minimum. SQL Server comes with some built-in tools that allow us to monitor changes, and depending on the architecture, we can create tools that allow us also to monitor and identify changes near the time that they occur.
