    Indexes are used to speed-up query process in SQL Server, resulting in high performance. They are similar to textbook indexes. In textbooks, if you need to go to a particular chapter, you go to the index, find the page number of the chapter and go directly to that page. Without indexes, the process…

locking in SQL Server is a mixed blessing! It is a SQL Server’s way of ensuring data integrity which is a basic requirement for any database management system but when users encounter a lot of blocking it makes the application appear slow and sometimes unusable.

Each database must have its own datadirectory that will have the filestream container in a subdirectory of that directory.  The setup should be like this: F:data3filestreamcontainer1filestreamfiles F:data2filestreamcontainer1filestreamfiles…

While adding an extra datafile to a tempdb I received the following popup.  Apparently the internal administration is messed up and Sqlserver still thinks that a file is still part of the database file administration but this is not anymore the case. Use the following query: SELECT * FROM sys.master_files WHERE DB_NAME(database_id) = ‘tempdb’ Even…
