smallint and char(3) (and I have added the data types to the original post).

ok, that's not what I thought you meant. I thought you meant flip all the bits.

This works for 0 and 1:

DECLARE @smallint smallint = 0
select @smallint...

The expectation, as in the OP, is that 0 becomes 1 and 1 becomes 0.  I didn't really mention -1; typically values are 0/1 for no/yes.

DECLARE @int...

The table would need to contain, and be keyed on, workerID, year and Course_Code.  This should be a unique key if that is your rule (that is, no single worker...

Consider, for example, with design #1, a unique constraint will insure that the same course is not entered twice for the same year.

But for design #2, you'd have to insure...

You should only ever use the first method, period, no matter what your current requirements are.

The second approach would be a maintenance and query nightmare.

You don't need to do point-in-time recovery if you take a differential at the exact point you want to restore to, just like with a full backup (which was OP's...

Perhaps you could take a differential backup instead of a log backup.  That would not interfere with any other backup process (and you wouldn't have to apply any tran logs...

Yes, recompile the table / view rather than individual proc(s).

If you recompile a proc, only that specific proc gets recompiled.  If you...
