Handling Attributes

Hello

I have a simple question that is hard to explain. I have drawn a little picture to help explain.

Basically I have table 1 and I want to get to table 2 based on the values in an attribute field. I know that there is a maximum of 12 unique values for any one D value. This means at max I would have 12 new fields (which can be named 1 - 12).

I have 1000's of D values in total.

Any advice on where to start, would be helpful. I have tried an intersect and join but found they only returned one value for each D.

Thanks
