How to include the total number of returned rows in the resultset from SELECT T-SQL command?

Question

I would like to ask if there is a way to include the total number of rows, as an additional column, in the returned result sets from a TSQL query using also the Row_Nu

Answer 1

SELECT  n ,
        COUNT(*) OVER ( PARTITION BY 1 )
FROM    ( SELECT    1 AS n
          UNION ALL
          SELECT    2 AS n
        ) AS t

Note that @@ROWCOUNT gives you row count from the previous command. Run this:

SELECT    1 AS n;

SELECT  n ,
        @@ROWCOUNT
FROM    ( SELECT    1 AS n
          UNION ALL
          SELECT    2 AS n
        ) AS t
