If you mean that you are looking at the value for parameterized_plan_handle and it's showing something like this:
What you're seeing is the handle for a plan that has not been parameterized. If you provide a parameterized query, you'll see a different value. For example, running this query:
SELECT *
FROM Sales.BuyingGroups AS bg;
Results in 0x. However, this query:
SELECT *
FROM Sales.BuyingGroups AS bg
WHERE bg.BuyingGroupID = 42;
Results in:
0x060007009A489A12E0FAC22DA3000000010000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
This is because the first query is not parameterized while the second query is. If you want to capture the plan_handle for all statements, I'd suggest adding the action plan_handle.
Just be cautious adding actions because they do come with added cost.
