Time out issue

When your app runs into a timeout on a database operation the error message may lead you in a wrong direction to fix things. Which happened to me so this is my little index to the docs.
A sqlConnection has a ConnectionTimeout property. It  is a property which determines the maximum number of seconds your code will wait for a connection to the database to open. It is set in the connectionstring to the database
data source=BROCHIS;initial catalog=Indato;integrated security=SSPI;Connect Timeout=60;
Opening the connection does not do anything in the database yet. That is handled by a SqlCommand, which could be part of a SqlDataAdapter. The SqlCommand has aCommandTimeOut. This is a settable property which determines the maximum number of seconds the command is given to execute the sql. By default this is 30 seconds. When you perform something costly in the database this is the one whose value you’ll have to change.
SqlCommand cmd;
if (bigJob)
   cmd.CommandTimeout = 60;
For both properties a value of 0 indicates to wait forever. Both properties also apply to non sqlserver database operations. They are defined in IdbConnection and IdbCommand.

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?
