Contained Database Authentication feature in SQL Server 2012

SQL Server 2012 introduces a new feature called Contained Database Authentication. The Contained Database Authentication feature allows the database to partially contain the data that was previously stored outside the database. In other words, once you enable the containment feature at the SQL Server instance level, you can create a database that can store user information/credentials inside the database itself (rather than having a login at instance level, which gets stored in the master database) and hence you don't need to create logins on the target instance (and do mapping of SID) again during database movement. Quite a relief...isn't it? For more information click here.

Usage and Benefits of Using WITH RESULT SETS In SQL Server 2012

SQL Server 2012 (Code name SQL Denali) introduces the WITH RESULT SETS clause with the EXECUTE statement, which lets you redefine the name and data types of the columns being returned from the stored procedure. This comes in very handy when you want to insert the records coming in a result set to a temporary table with a specific column name and data type and you don’t want to rely on what is being returned by the stored procedure.
The WITH RESULT SETS clause can also be used with a stored procedure, which returns multiple result sets and for each result set you can define the column name and data types for each column separately, for more information click here.

Data Driven Report Subscription in SSRS 2008 R2

In my last article I talked about standard subscription in which we need to specify whatever parameters the report expects at the time of subscription creation and which cannot be changed at runtime; in this article we are going to discuss and use data-driven subscription.
In data-driven subscription the data or parameter values required during execution of the report can come from a query from a database including recipient list, delivery method and parameter values needed for each recipient's report execution, which makes it a dynamic subscription that gets required data during run time from the external data source, click here fore more information.
