What do you get when you run it like this...


Select count(*) from CaRates as a
Where exists
(select * from xtCaRates as b
where a.ptccp7 = b.ptccp7 and
a.ptccp6 = b.ptccp6 and
a.ptccp5 = b.ptccp5 and
a.ptccp4 = b.ptccp4 and
a.ptccp3 = b.ptccp3 and
a.ptcpp2 = b.ptccp2 and
a.ptcpp1 = b.ptcpp1 and
(a.Term = 0 or a.Term > :xDate))


There's clearly more than a 1 to 1 match between the two tables. Your
update is just doing an EXIST meaning find just one record in xtCaRates.
But your validation is joining the two tables together. So if table
CaRates had one record were

ptcpp1 = 1
ptcpp2 = 2
ptcpp3 = 3
ptcpp4 = 4
ptcpp5 = 5
ptcpp6 = 6
ptcpp7 = 7

And xtCaRates had Two records with the same values, your select will return
a count of two, not one like the update EXISTS clause did.

If there were two records in both tables, then the result of count would be
4 and so on.

I'm having a problem trying to get an accurate count of my records being
updated.

Here is the SQL statement for the update:

Exec Sql
Update CaRates as a
Set a.Term = :xTermDate
Where exists
(select * from xtCaRates as b
where a.ptccp7 = b.ptccp7 and
a.ptccp6 = b.ptccp6 and
a.ptccp5 = b.ptccp5 and
a.ptccp4 = b.ptccp4 and
a.ptccp3 = b.ptccp3 and
a.ptcpp2 = b.ptccp2 and
a.ptcpp1 = b.ptcpp1 and
(a.Term = 0 or a.Term > :xDate));

The update seems to work just fine, but I'm trying to validate the results
and this statement always seems to give me more records than I have:

SELECT count(*)
FROM CaRates a, xtCaRates b WHERE a.ptccp7 = b.ptccp7
and a.ptccp6 = b.ptccp6 and a.ptccp5 = b.ptccp5 and a.ptccp4 =
b.ptccp4 and a.ptccp3 = b.ptccp3 and a.ptccp2 = b.ptccp2 and
a.ptccp1 = b.ptccp1
and (a.Term= 0 or a.Term > 20121214 and
a.Term <> 20121231)

Any help or suggestion would be greatly appreciated.
