Question

I want to get a result like this, in a single list.

TYPE    | subtype | Total
  A     | z       | 5
  A     | y       | 3
total A | NULL    | 8
  B     | i       | 6
total B | Null    | 6

How can I do this in a sql stored procedure?

Edit: I work in T-Sql for Sql server

Answer 1

This will work for all kinds of SQL.

Select type, subtype, total from source
union all
Select type, 'Total', sum(total) from source group by type
order by type

If you have a specific kind of SQL there may be a more efficient solution
