Table Size and Missing FK Indexes

I am bringing an oldie back with another twist.  I recently ran into the need to correlate information between a couple of different queries that I like to use.  The two scripts returned different pieces of data about tables in a database.  This information was table size and missing foreign key indexes.

I needed to combine the two queries due to a desire to create indexes on foreign keys based on table size.  The premise behind this was to get the biggest bang for the buck initially as we work toward optimizing a database.  We happened to know heading into this that some of the larger tables are the most heavily queried tables as well.

So, here is what I did to get that information quickly.

The change is not overly much.  I added a subquery via a cross apply to get the missing foreign key info.  Then I return the pertinent columns back to the Select query.
