Activity Monitor in SQL

Activity Monitor is new tool in SQL Server which displays activity in five sections.
1) Overview,
2) Processes,
3) Resources Waits,
4) Data File I/O,
5) Recent Expensive Queries.

It is one of the new and very useful tool introduced by SQL Server.

Activity Monitor captures all the information at server level.

To start Activity Monitor:
From Standard Toolbar (Standard Toolbar can be made visible from here : Menu >> View >> Toolbar >> Standard) and from “Right Click” on SQL Server Node and select Activity Monitor

If on starting activity server you do not see any info , then give the “View Server State” permission to user name to view data of Activity Monitor. We can give permission either using T-SQL or using SSMS.

T-SQL to give permission to user to view Activity Monitor:
GRANT VIEW SERVER STATE TO <username>

SSMS to give permission to user to view Activity Monitor:
Right click on server name -> Properties - > Permissions -> username-> View Server State(in Explicit tab)

Note : You cannot give permission to yourself using the T-SQL method , but can do so using SSMS

Activity monitor itself is very expensive process. The tool, which helped to debug the performance issues, also helped (negatively) to bring down the server. Make sure you close the activity monitor after use.

Do's and Don't SQL

Do's: Writing comments whenever something is not very obvious, as it won’t impact the performance.  (--) for single line  (/*…*/) to mark a section Use proper indentation Use Upper Case for all SQL keywords. SELECT, UPDATE, INSERT, WHERE, INNER JOIN, AND, OR, LIKE. Use BEGIN... END block for multiple statements in conditional code  Use Declare and Set in beginning of Stored procedure Create objects in same database where its relevant table exists otherwise it will reduce network performance. Use PRIMARY key in WHERE condition of UPDATE or DELETE statements as this will avoid error possibilities. If User table references Employee table than the column name used in reference should be UserID where User is table name and ID primary column of User table and UserID is reference column of Employee table. Use select column name instead of select * Use CTE (Common Table Expression); its scope is limited to the next statement in SQL query, instead of...

SQL Server 2008 - Inline Variable Assignment

Microsoft SQL Server 2008 brings in a new feature of 'Declaring and Assigning' a variable all in a single line. Earlier, while using SQL 2005 and earlier versions, we had to declare a variable before assigning it. This feature is explained in detail below. In SQL 2005 and earlier versions we had to write: Declare @age int Declare @name nvarchar(25) Declare @date date Set @age = 25 Set @name = "Garry" Set @date = GETDATE() With SQL 2008 we can combine both these statements to write Declare @age int = 25 Declare @name nvarchar(25) Declare @date @date = GETDATE() Advantage : This helps us to write less code, yet get the same functionality. Even though this feature has been available it is not being used in many projects because of backward compatibility issue. If the same code is being used on both 2005 and 2008 server we would prefer writing in a format compatible to both. Do share with us :  Would you like to use this new method? If not, why?
