To find the current year and last year revenue in a SQL query, you can use the following approach:

```sql
SELECT
YEAR(order_date) AS year,
SUM(revenue) AS total_revenue
FROM
sales
WHERE
YEAR(order_date) IN (YEAR(CURDATE()), YEAR(CURDATE()) - 1)
GROUP BY
YEAR(order_date);
```

This query filters the sales data for the current year and the previous year, grouping the results by year to show the total revenue for each year.
