Hi Adam, all,

You could you use UNION to make this all execute in a single query.
Sure you can use UNION to get the data or the (separate) counts from the four tables, but a plain UNION can not sum over these individual parts.
I have not checked whether you can have a UNION in a subquery, this would be your only chance to do the OP's task in a single SQL statement. But IMO, it is better structure to do four separate SELECTs on the individual tables than to force it all into one.
