I am looking to pivot some data from this query

```
select 
    count(*) as total_customers,
    sum(last_year) as customers_in_last_year
    sum(two_years) as customers_in_last_2_years
from
    Customers

```

which returns this result set:

```
total_customers    customers_in_last_year    customers_in_last_2_years
500                  100                         200

```

What I want to do is flip that to the below, any help?

```
total_customers                500
customers_in_last_year         100
customers_in_last_2_years      200

```

Thanks
