Hi

Please let me know

How Xml query plan is internally converting to graphical query plan by sqlserver engine.

SELECT [cp].[refcounts]
, [cp].[usecounts]
, [cp].[objtype]
, [st].[dbid]
, [st].[objectid]
, [st].[text]
, [qp].[query_plan]
FROM sys.dm_exec_cached_plans cp
CROSS APPLY sys.dm_exec_sql_text ( cp.plan_handle ) st
CROSS APPLY sys.dm_exec_query_plan ( cp.plan_handle ) qp ;

when i execute this querry it will give the out put in XMl plan,when i click any xml paln it gives graphica plan.

how it is coming????

Its all down to the XML name space in the well formed XML

It isn't the engine that does that. It's Management Studio.

Yep, Gus has it nailed. Management Studio is making that conversion. Plus, in the engine, SQL Server itself is using a binary to deal with execution plans, not XML, so there's a conversion to XML taking place there and then you get the XML which is converted to graphical. You can look at the XML again by right clicking on any graphical plan and selecting the XML menu choice to see the raw data.
