Estimated Query Execution Plan Vs Actual Query Execution Plan - SQL Server

Hi,

What are the main differences between "Estimated Query Execution Plan" and "Actual Query Execution Plan" ? Does the "Estimated Query Execution Plan" includes all the rows from result set (Full result set) ?

Thanks

Not enough much difference..
Estimated Execution plan is generated once the query is compiled and query plan is added to plan cache..

Actual Execution plan would be generated once the query is run and 99.99% it would take the plan which is cached by Estimated execution plan..
