Once again I come to the masters of all things SQL...

I have 2 files:

File TCKTHIST:
TICKET#
CUSTOMER#
TRAN_DATE (CCYYMMDD, likely not the same value as POST_DATE)
POST_DATE (CCYYMMDD)


File NEWTCKTS:
TICKET#
CUSTOMER#
TRAN_DATE (CCYYMMDD)

I need to work up an SQL statement that will find all entries in TCKTHIST
with a post_date = yesterday and which are not in file NEWTCKTS. Fields
TICKET#, CUSTOMER# and TRAN_DATE are common fields to both files; POST_DATE
is only in TCKTHIST.

Thanks to SQL's ongoing lack of any sort of decent date handling, I'd calculate the date and then do this:

select * from tckthist exception join newtckts
using (ticket#, customer#, tran_date)
where post_date = 20110829

If that's out of the question, use iDate:

select * from tckthist exception join newtckts
using (ticket#, customer#, tran_date)
where iDate(post_date,'*CCYMD') = (current_date - 1 day)
