I'm trying to add a column named `Ready` to my query that checks if the sum of `Complete` is = to the sum of `Total` and places 'Y' if True and 'N' if FALSE.

Here is my query that works producing 4 columns

```
 SELECT pc.Sub,
    SUM(CASE WHEN `SheetStatus` LIKE 'Complete' THEN 1 ELSE 0 END) AS 'Complete',
    SUM(CASE WHEN `SheetStatus` LIKE 'Not started' THEN 1 ELSE 0 END) AS 'Not Started',
    SUM(CASE WHEN `CheckSheet` LIKE '%' THEN 1 ELSE 0 END) AS 'Total'        
FROM `pc`
Group By pc.Sub WITH ROLLUP

```

I just cant figure out how to create the extra column if it is possible at all.
Regards
