This is my table.

SQL

select * from table1

--------------------------------------------------------------------------------
name v1 v2 v3
--------------------------------------------------------------------------------
a 1.2 1.2 2.0
b 2.1 2.4 3.4
c 1.0 8.5 0.56
d 2.7 2.5 2.6
--------------------------------------------------------------------------------
I need this result.
--------------------------------------------------------------------------------
name v1 v2 v3
--------------------------------------------------------------------------------
avg 1.75 3.65 2.14(this new row)
median 1.65 2.45 2.3 (THIS new row)
a 1.2 1.2 2.0
b 2.1 2.4 3.4
c 1.0 8.5 0.56
d 2.7 2.5 2.6
--------------------------------------------------------------------------------
The row Avg is v1 values(1.2,2.1,1.0,2.7) is 1.75
v2 values (1.2,2.4,8.5,2.5) is 3.65
v3 values (2.0,3.4,0.56,2.6) is 2.14

The row avg is added dynamically using avg().

The row Median is half of the value. It is dynamically added
v1(1.2,2.1,1.0,2.7) median is 1.65.

Please anyone help me. Thanks a lot.

One example here: http://weblogs.sqlteam.com/jeffs/archive/2010/08/30/sql-server-calculate-median.aspx[^]

You can also use CTE which would be performing more well. An example: http://www.sqlmag.com/article/tsql3/calculating-the-median-gets-simpler-in-sql-server-2005[^]

And also if you want, you can create your own aggregate, an example: Custom Aggregates in SQL Server[^]
