What is an execution plan? When would you use it? How would you view the execution plan?..

Answer / sumit

An execution plan is basically a road map that graphically
or textually shows the data retrieval methods chosen by the
SQL Server query optimizer for a stored procedure or ad-hoc
query and is a very useful tool for a developer to
understand the performance characteristics of a query or
stored procedure since the plan is the one that SQL Server
will place in its cache and use to execute the stored
procedure or query. From within Query Analyzer is an option
called "Show Execution Plan" (located on the Query drop-
down menu). If this option is turned on it will display
query execution plan in separate window when query is ran
again.
