Question

Have a TSQL view, which I need to group by one column, however, am using nhibernate(C#) and am required to specify the Id column too.. my query looks like:

SELECT
    row_number() over(order by id)as Id,
        column_name,..etc
from tblName
group by column_name

which gives me an error that the Id has to be included in the group by clause.

Alternatively, I can write:

SELECT
    row_number() over(order by id)as Id,
        column_name,..etc
from tblName
group by column_name, id

which return multiple rows of the same column_name name.

Is there a way around this?

Answer 1

I think you want to do this:

  Select row_number() over(order by column_name) as ID, column_name from (
      Select distinct column_name from tblName
   ) as A
