Hello. I am glad you liked it Unfortunately, when you apply the plan, the current plan for the same query is deleted. Therefore, before applying the plan, you should save old plan for the same query. When you want to revert back, you should apply the old one by removing the applied one. Step 1 Save the old plan before applying the plan Step 2 If you want to revert back, run the below and remove the applied plan: EXEC sp_control_plan_guide N'DROP', N'TestPlanGuide'; Step 3 Apply the old plan in the same way. With high possibility, you can just rerun the query and it will generated the same inefficient plan. But in case, it does not, you can just apply the same saved one

Hello. I am glad you liked it
Unfortunately, when you apply the plan, the current plan for the same query is deleted.
Therefore, before applying the plan, you should save old plan for the same query.
When you want to revert back, you should apply the old one by removing the applied one.
Step 1
Save the old plan before applying the plan
Step 2
If you want to revert back, run the below and remove the applied plan:
EXEC sp_control_plan_guide N'DROP', N'TestPlanGuide';
Step 3
Apply the old plan in the same way.
With high possibility, you can just rerun the query and it will generated the same inefficient plan. But in case, it does not, you can just apply the same saved one
This doesn't work if the proc contains more than one statement, which is quite likely
Oh i see. I never tried multi statement batch
