I want to insert the ff:
1.) JSMITH 08-15-2005 8 VAC
2.) DOE 08-16-2005 8 VAC
#1 should fail because there is already 8 hours entered as being
Worked on 08-15-2005 (same date).
sorry, did not notice the duplicates before my previous reply.
you could do something like
insert into A select 'JSMITH','08-15-2005',8,'VAC'
where
8 != (select sum(hours) FROM A
WHERE emp = 'JSMITH'
AND date = '8-15-2005');
Wouldn't that fail if JSMITH had only worked 7 hours on 8-15? I'm
guessing he'd still want it to fail since adding that 8 hours ov VAC would
result in a 15 hour day... so maybe something like?
insert into A select 'JSMITH','08-15-2005',8,'VAC'
WHERE
8 >= 8 + (select sum(hours) FROM A
WHERE emp = 'JSMITH'
AND date = '8-15-2005');
?

choose an index scan if your joining column's datatypes do not
match
