Description: JOIN and capitial letters in Table Row
Details:

I had a table as like the following named products:

id ClientID ProductID is_multiqty is_active
1 12345 1000001 1 1
2 12345 1000002 0 1

and another table named productoptions with the following:

id ProductID Sku Description OptionID minpayments maxpayments maxqty is_acti
ve
1 1000001 somedesc1 1 1 1 0 1
1 1000002 CX7535 somedesc2 1 1 3 0 1

when I ran the following sql I got: ""ERROR: column product.ProductID does
not exist":

SELECT *
FROM products
JOIN productoptions
ON products.ProductID = productoptions.ProductID

However, if i changed the name of the fields in the database to:

"productid"

It would work fine.
