The TaskNames would have to be contiguous for that method to work.  I wanted to also handle some other TaskName appearing between "Distribute" and "Print", just in case.

SELECT JobID
FROM dbo.tblPrintTask
GROUP BY JobID
HAVING MAX(CASE WHEN TaskName = 'Distribute' THEN TaskID END) < 
    MAX(CASE WHEN TaskName = 'Print' THEN TaskID END)

You could easily have an order of magnitude more rows in SG table than in T, and if you have a phone app waiting for the response, I would still...

Nice.

Also, you don't have to change the FKs in other tables if you need one for just ID.  Instead, just add a unqiue nonclus index on ( ID ); it...

Because to determine all the Tests that haven't been fully graded could require scanning a very large number of StudentGrade rows.

If, instead,...

I would use option 2 in this case.  The safest way to set the flag consistently accurately is to use a trigger on the StudentsGrade table.

SQL captures the size of backups in table msdb.dbo.backupset.  Thus, you can query that table to add up total space used for backups.

You could do as below.  You can't really GROUP BY ID, because that would separate the Small, Medium and Large into separate rows.

SELECT    ...

IF you're on Enterprise Edition, you can do an online build of an index for SpoolStartDt.  Then you can use that index to do the DELETEs.  If you're not on...

I haven't ultra-tuned this, but see if it gives you the correct results.

Since it's not an index seek, partitioning should still help the query by reducing the number of pages it has to search.  Once again, verify that by looking at the...

It's just a predicate / search, it's not an index SEEK.
