RE: [MS_AccessPros] Primary Index

 

Sarah,
 
Can you add a "NA" color to your color table?

Subject: [MS_AccessPros] Primary Index



I have a Product table.
The primary key is the Product ID and Color ID. The same Product ID  is available in multiple colors.
Some Products dont have a Color, but I can not update the record without entering something in the Color ID.
I have tried space , but it does not accept it. 
Is there anyway I can have the Color ID as part of the Primary key even though in same cases it is blank/null?
Thanks
Sarah
