SQLServer has three ways to show the plan: graphical plans, text plans, and
XML plans. Actually, it is pretty advanced. When using the text plans, users
can set the output formats:
1. SHOWPLAN_ALL â A reasonably complete set of data showing the estimated
execution
plan for the query.
2. SHOWPLAN_TEXT â Provides a very limited set of data for use with tools
like osql.exe.
It, too, only shows the estimated execution plan
3. STATISTICS PROFILE â Similar to SHOWPLAN_ALL except it represents the
data for
the actual execution plan.
I found a 300-pages book `SQL Server Execution Plans`. For details, you can
[download and read
it](http://download.red-gate.com/ebooks/SQL/eBOOK_SQLServerExecutionPlans_2Ed_G_Fritchey.pdf).
