(I submitted this twice since I had forgotten to use the "pre" command to format the output below.)
I am trying to write a SQL Statement that has three tables. I am looking at WIRE STANDS being received from various customers WITHOUT WIRE on them into our Company and a certain number being sent out to customers WITH WIRE on them.
We have the following tables:
CUSTOMERS-Holds all of our customers company names and CUST ID.
STANDSIN - with a field called Qty for stands received from customers
STANDSOUT- also with a field called Qty for stands shipped out
Customer has a CUST field and is indexed as CUST.
StandsIn and StandOut also have CUST as one of their related fields to the CUSTOMER table.
I want to end up with a report GROUPED by CUSTOMERS showing stands Received and Stands shipped out as followed:
NAME OF CUSTOMER QTY Recv'd QTY Sent Out Difference (Recv'd-Shipped)
CUSTOMER_A 13 23 -10
CUSTOMER_B 98 58 40
CUSTOMER_C 112 140 -28
CUSTOMER_D 1000 980 20
What we are trying to do is to focus on the customers who have not been returning our stands, so that if we see a negative number, we know that that customer has not been returning our WIRE STANDS and can then focus on them.
I tried a regular UNION SQL Statement, but that didn't seem right. Would this require more of a LEFT OUTER JOIN type of statement?
