Quite often, we need to know how many any particular objects have been executed on our server and what their execution plan is. I use the following handy script, which I use when I need to know the details regarding how many times any query has ran on my server along with its execution plan. You can add an additional WHERE condition if you want to learn about any specific object.
SELECT cp.objtype AS ObjectType,
OBJECT_NAME(st.objectid,st.dbid) AS ObjectName,
cp.usecounts AS ExecutionCount,
st.TEXT AS QueryText,
qp.query_plan AS QueryPlan
FROM sys.dm_exec_cached_plans AS cp
CROSS APPLY sys.dm_exec_query_plan(cp.plan_handle) AS qp
CROSS APPLY sys.dm_exec_sql_text(cp.plan_handle) AS st
--WHERE OBJECT_NAME(st.objectid,st.dbid) = 'YourObjectName'
In result set, you will find the last column QueryPlan with XML text in it. Click on it, and it will open a new tab displaying the graphical execution plan.
You can also save the newly opened tab in XML format with the extension .sqlplan. When this new file is opened in SQL Server Management Studio, it will automatically display the graphical representation of the XML Plan.
It is a quite simple script, but it works all the time.
