Complex Query Help

Hi All,

I'm trying to consolidate three tables into a single result and I'm wondering if someone can give me a few ideas....

I have these tables:

TABLE A
Plant Code
Part Number
Part Colour
Scan Date (in three integer fields: YY, MM, DD (don't ask - the legacy programmers did not know how to use timestamps!))

TABLE B
Plant Code
Part Number
Bin Type

Table C
Plant Code
Part Number
Ship Type

What I want to do is combine the values into a result that has these fields for 02/09/2011:
Bin Type
Quantity for each bin type

Quantity is a sum of each bin type for the selected plant/part #.
IE:
Plant 1, Part: 12345, Bin Type: X1
Plant 1, Part: 67711, Bin Type: X2
Plant 2, Part: 67711, Bin Type: X2
Plant 3, Part: 90009, Bin Type: X3
Plant 2, Part: 90191, Bin Type: X1
Plant 1, Part: 12345, Bin Type: X1

If the above was entered into the system, I would expect the report to be:
Plant Code | Part Number | Bin Type | Quantity
1 | 12345 | X1 | 2
1 | 67711 | X2 | 1
2 | 67711 | X2 | 1
3 | 90009 | X3 | 1
2 | 90191 | X1 | 1

However, this is not the case - I am getting an insane amount of records when I try this (I know it is incorrect because one of the bins says we brought in over three million of them in a single day!!):

select b.bintype, count(b.bintype)
from tablea a, tableb b, tablec c
where a.partno = b.partno and a.partno = c.partno
and a.plantcode = '1' and c.shiptype = 'PS'
and a.scyy||a.scmm||a.scdd = '201129'
group by b.bintype

Anyone have any idea how I can rewrite this statement so that it gives me the correct values?

Thanks!
