Good point. I keep forgetting that SQL Server does not follow the
FIPS-127 rules about keeping at least five decimal places of seconds
like other products. Generally goiing to 1/100 of a second has worked
for me in the real world -- CAST ('2006-01-01 23:59:59.99' AS
DATETIME).
If we had the OVERLAPS predicate, we could use that, but I prefer the
BETWEEN with adjusted times in the non-conformng SQLs I use. I can
move the code with a text change.
