I got a question from one of our UG member. He asked whether we can use SQL Server 2005 performance dashboard with SQL Server 2008. When we tried at the session we failed to implement it in SQL2K8. I was just thinking this today and planned to try this. I found out the reason why we failed to implement and what has changed in the query.
In this article we are going to see how to partition a existing table in a database. In my working place I got a request from client to partition an existing table, I have searched in BOL but couldnt find the exact detail how to do it. Ive figured out that and Implemented successfully, Im Just sharing the steps with you so that this might be helpful to you.
Forceseek hint is a new addition to SQL Server 2008. It forces the query optimizer to use an Index seek instead of Index scan. Forceseek applies to both clustered and nonclustered index seek operations. It can be specified for any table or view in the FROM clause of a SELECT statement and in the FROM clause of an UPDATE or DELETE statement.
In earlier versions of SQL Server in order to perform INSERT, UPDATE or DELETE we have to have separate T-SQL statements. With the introduction of SQL Server 2008 we have MERGE statement which helps in simplifying this. It allows us to perform DML operations based on certain JOIN conditions in single statement.
A new T-SQL feature is available in SQL Server 2008 which allows us to pass a set of rows as a parameter to stored procedures or functions. Table-Valued Parameter (TVP) allows us to send multiple rows of data to a stored procedure or a function without the need to pass so many parameters or creating temp tables.
