List few advantages of Stored Procedure.
· Stored procedure can reduced network traffic and latency, boosting application performance.
· Stored procedure execution plans can be reused, staying cached in SQL Server's memory,
reducing server overhead.
· Stored procedures help promote code reuse.
· Stored procedures can encapsulate logic. You can change stored procedure code without
affecting clients.
· Stored procedures provide better security to your data.
Which virtual table does a trigger use?
Inserted and Deleted.
What is Self Join?
This is a particular case when one table joins to itself, with one or two aliases to avoid confusion. A self
join can be of any type, as long as the joined tables are the same. A self join is rather unique in that it
involves a relationship with only one table. The common example is when company have a hierarchal
reporting structure whereby one member of staff reports to another.
What is Cross Join?
A cross join that does not have a WHERE clause produces the Cartesian product of the tables involved
in the join. The size of a Cartesian product result set is the number of rows in the first table multiplied
by the number of rows in the second table. The common example is when company wants to combine
each product with a pricing table to analyze each product at each price.
