I've been searching for about half an hour trying to work this out and thought it would be easy to do.
I have a dense rank in my script:
,DENSE_RANK() OVER (ORDER BY ISNULL(a.[Country Name],''),a.[City]) + 3 AS CityRankRow
Which I need to start from number 4 so did + 3
so I get:
London 4
London 4
London 4
Madrid 5
Paris 6
Paris 6
Paris 6
Paris 6
What I now need is Dense Rank to increment not by 1 but 3 each time so I get:
London 4
London 4
London 4
Madrid 7
Paris 10
Paris 10
Paris 10
Paris 10
Am I missing something here, thought it would be easy to do but I'm going in circles.
