I wasn't 100% sure if 101 and 102 could appear more than once in the risk table, so I coded it to allow that, just in case.

If each can appear...

What result do you want?  You never explicitly stated the results you want to see.

Maybe try this:

select k.charges,
sum(case when k.range>='101' then charges else 0 end) as '101charges',
sum(case when k.range>='201' then charges else 0 end) as '201charge'

If you can afford to have CASCADE in effect, drop and recreate the index with ON DELETE CASCADE specified.

Hmm, yeah, if not, we'll have some complex code to write.  We...

It depends, but, yes, if this query is vital for you, then change the clustering key to ( registration_date, UserID /*assuming a unique UserID*/ ) (the PK can still be...

SQL itself will delete from the FK-related tables if you "tell" it to: that is, you set the ON DELETE CASCADE option on for that FK.

Great, glad that resolved it.  Autoclose on or taking the db offline were the only things I could think of that would cause that to happen.

I believe heaps do show up, just under index_id 0 rather than 1.

OK, I finally found notes on the sys view I was trying to remember:

sys.dm_db_file_space_usage

This time, that should (actually) help you determine what you need to know (you would likely need...

So sorry, obviously I didn't look closely enough.

I can't imagine the db has autoclose on or that the db is taken offline, so, yeah, that is really weird.
