testy this one is i tell ya, testy...

ok.  i have a table, with 4 columns:

1. acctNo
2. trxAmt
3. trxType
4. trxId

where trxType might be [d] or [r]
and for every [r] there is a matching
[d].  i want to get acctNo's that match
but only when the trxAmt are opposing
value matches...

could be...

acctNo: 100
trxAmt: -545.00
trxType: r
trxId: 500

and the matching one would look like

acctNo: 100
trxAmt: 545.00
trxType: r
trxId: 510

basically a reversal of a mistaken transaction....
now, the problem lies in the fact that there may
be another transaction that matches the acctNo
but has nothing to do with this payment reversal.

can this be done?

here is what i have, and its giving me ones that
match the acctNo, but are extra, since they are not
matching in the dollar value...

select acctNo, trxAmt from transactions
where (trxtype = 'd' or trxType = 'r')
and acctNo in (select acctNo from colthist where trxAmt like '%-%')
group by trxAmt, acctNo

here is a sample set, the first one that pulls up, and clearly
illustrates
the problemo ;)

   127  -154.50 #1
   127  154.50  #2      
   127  618.00  #3
   133  -245.00 #4
   133  -196.00 #5
   133  -98.00  #6
   133  25.00           #7
   133  50.00           #8
   133  85.11           #9
   133  98.00           #10
   133  196.00  #11
   133  245.00  #12
   133  500.00  #13

where 1 and 2 are correct but three isnt, and 4,5,6 match 10,11 and 12.
but, i dont want 3,7,8,9 or 13 to be there.

confused, i hope not, but i hope this is possible in a query...
