Use sp_set_qplan to change the abstract plan of an existing plan. You can specify a maximum of 255 characters for a plan. If the abstract plan is longer than 255 characters, drop the old plan with sp_drop_qplan, then use create plan to create a new plan for the query.
When you change a plan with sp_set_qplan, plans are not checked for valid abstract plan syntax and the plan is not checked for compatibility with the SQL text. Immediately check all plans modified with sp_set_qplan for correctness by running the query for the specified ID.
To find the ID of a plan, use sp_help_qpgroup, sp_help_qplan or sp_find_qplan. Plan IDs are also returned by create plan and are included in showplan output.
Any user can execute sp_set_qplan to change the text for a plan that he or she owns. Only the system administrator or the database owner can change the text for a plan that belongs to another user.
