Hi,

I have a table with customer number and memo types left on their account.
e.g.

---------------------------
Customermemo
---------------------------
cnum     memotype
a1               debt
b1                good
a1                paid
b1                debt
b3                new
b2                leaving
b2                left
b3                paid

I have another table with only customer number
----------------
Customer
------------------
customerno
a1
b1
a2
b2
b3
a3

Now i am trying to get distinct customer number without memotype debt ( that customer number should be in both tables)

here is a query

select distinct(cnum) from customermemo, customer where
memotype <> 'DEBT'
and
cnum = customerno

But still i kept on getting a1 in the output though i do not want anything with the memo type DEBT.

try the updated below:

select distinct(cnum) from customermemo cm, customer c
where ltrim(rtrim(cm.memotype)) <> 'DEBT' and cm.cnum = c.customerno

even better as you may have a case sensitive database and "debt" <> "DEBT"

select distinct(cnum) from customermemo cm, customer c
where upper(ltrim(rtrim(cm.memotype))) <> 'DEBT' and cm.cnum = c.customerno

Yes.  What is great is when you see the same solution copied and pasted in both questions.  Can you say wishful thinking?

I have posted a message in CS.  More than likely points will be halved in both questions.
