postgres 8.2.17
I am trying out the crosstab function (tablefunc contrib) for reporting
needs and I'm having a problem.
I have customers and products and the data is the quantity purchased. I
am grouping by customername, productname in the source sql. My category
sql depends if I want the products or customers to be the columns.
When I make customers the rows and products the columns, it works fine.
But when I make customers the columns and products the rows, there are
duplicate product rows.
Is there a way to group the product rows so that the data results come
back correct?
