I read somewhere online and in a Microsoft Press book there is a field declaration attribute that can be used to indicate NULL VARCHAR values should not consume space at the leaf-level instead of consuming a few characters per leaf.

Could someone help me identify where that attribute is?

I cant remember what the Attribute keyword is but I remember seeing it because of the value of saving the empty 2 bytes and make it a 0 byte storage for no data.

    Pretty sure you are asking about SPARSE columns. Do you have further questions about them, or did you just need to be reminded what they're called? Jul 13, 2012 at 18:43
  • I knew it was new to 2008(r2) but couldnt remember the keyword for the new attribute for varchar data type.
