Forcing Query Plans

Is it possible to force a query plan on a Stored procedue. I have attempted the following and i receive a Incorrect syntax near the keyword 'OPTION'. Any ideas?

EXEC testdatabases..testprocedure

OPTION (USE PLAN N'
<ShowPlanXML xmlns=
"http://schemas.microsoft.com/sqlserver/2004/07/showplan" Version="0.5"
Build="9.00.1187.07">
<BatchSequence>
<Batch>
<Statements>
...
</Statements>
</Batch>
</BatchSequence>
</ShowPlanXML>
')
GO

You could use OPTION and USE PLAN only with SELECT/INSERT/DELETE/STATEMENTS. So move your plan in body of stored procedures.

If you couldn't change your stored procedure use Plan Guide by sp_create_plan_guide http://msdn2.microsoft.com/en-us/library/ms179880.aspx
