Ok. Here's TABLE A
emp date hours type
JSMITH 08-15-2005 5 WORK
JSMITH 08-15-2005 3 WORK
JSMITH 08-25-2005 6 WORK
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).
Any suggestions?
