I have a table like this

a1      a2       a3      a4     a5   a6       a7     a8     a9       a10     a11...a25

To get a table like:

ID       Name           value
-------------------------------------
1   SQRT(SUM(a1*a1))    11.521301

24  SQRT(SUM(a24*a24))  214.907172
25  SQRT(SUM(a25*a25))  307

I am doing:

 INSERT #temp (ID,NAME,Value) (
              SELECT 1, 'SQRT(SUM(a1*a1))', SQRT(SUM(a1*a1)) FROM myTable
    UNION ALL SELECT 2, 'SQRT(SUMa2*a2)) ', SQRT(SUMa2*a2)) FROM myTable
    UNION ALL SELECT 3, 'SQRT(SUMa3*a3)) ', SQRT(SUMa3*a3)) FROM myTable
    UNION ALL SELECT 4, 'SQRT(SUMa4*a4)) ', SQRT(SUMa4*a4)) FROM myTable
    UNION ALL SELECT 5, 'SQRT(SUMa5*a5)) ', SQRT(SUMa5*a5)) FROM myTable
    UNION ALL SELECT 6, 'SQRT(SUMa6*a6)) ', SQRT(SUMa6*a6)) FROM myTable
    UNION ALL SELECT 7, 'SQRT(SUMa7*a7)) ', SQRT(SUMa7*a7)) FROM myTable
    UNION ALL SELECT 8, 'SQRT(SUMa8*a8)) ', SQRT(SUMa8*a8)) FROM myTable
    UNION ALL SELECT 9, 'SQRT(SUMa9*a9)) ', SQRT(SUMa9*a9)) FROM myTable
    UNION ALL SELECT 10, 'SQRT(SUMa10*a10)) ', SQRT(SUMa10*a10)) FROM myTable
    UNION ALL SELECT 11, 'SQRT(SUMa11*a11)) ', SQRT(SUMa11*a11)) FROM myTable
    UNION ALL SELECT 12, 'SQRT(SUMa12*a12)) ', SQRT(SUMa12*a12)) FROM myTable
    UNION ALL SELECT 13, 'SQRT(SUMa13*a13)) ', SQRT(SUMa13*a13)) FROM myTable
    UNION ALL SELECT 14, 'SQRT(SUMa14*a14)) ', SQRT(SUMa14*a14)) FROM myTable
    UNION ALL SELECT 15, 'SQRT(SUMa15*a15)) ', SQRT(SUMa15*a15)) FROM myTable
    UNION ALL SELECT 16, 'SQRT(SUMa16*a16)) ', SQRT(SUMa16*a16)) FROM myTable
    UNION ALL SELECT 17, 'SQRT(SUMa17*a17)) ', SQRT(SUMa17*a17)) FROM myTable
    UNION ALL SELECT 18, 'SQRT(SUMa18*a18)) ', SQRT(SUMa18*a18)) FROM myTable
    UNION ALL SELECT 19, 'SQRT(SUMa19*a19)) ', SQRT(SUMa19*a19)) FROM myTable
    UNION ALL SELECT 20, 'SQRT(SUMa20*a20)) ', SQRT(SUMa20*a20)) FROM myTable
    UNION ALL SELECT 21, 'SQRT(SUMa21*a21)) ', SQRT(SUMa21*a21)) FROM myTable
    UNION ALL SELECT 22, 'SQRT(SUMa22*a22)) ', SQRT(SUMa22*a22)) FROM myTable
    UNION ALL SELECT 23, 'SQRT(SUMa23*a23)) ', SQRT(SUMa23*a23)) FROM myTable
    UNION ALL SELECT 24, 'SQRT(SUMa24*a24)) ', SQRT(SUMa24*a24)) FROM myTable
    UNION ALL SELECT 25, 'SQRT(SUMa25*a25)) ', SQRT(SUMa25*a25)) FROM myTable
    )

How could I modify the query so it is dynamic maybe lots of columns (more than 25..) and to get a result like each column by each column:

 ID      Name       value

The queries below dynamically generate a SQL statement that consists of the UNIONED statements that you desire. Then you just run exec sp_executesql on that generated statement and insert the results into your temp table.

create table #temp (
    ID int identity,
    Name varchar(100),
    Value decimal(18,6))

declare @sql nvarchar(max)

select
    @sql = coalesce(
        @sql + '
    UNION ALL SELECT ''SQRT(SUM(' + a.COLUMN_NAME + '*' + b.COLUMN_NAME + '))'', 
                    SQRT(SUM(' + a.COLUMN_NAME + '*' + b.COLUMN_NAME + ')) FROM myTable',
        'SELECT ''SQRT(SUM(' + a.COLUMN_NAME + '*' + b.COLUMN_NAME + '))'', 
                    SQRT(SUM(' + a.COLUMN_NAME + '*' + b.COLUMN_NAME + ')) FROM myTable')
from
    information_schema.COLUMNS a
    cross join information_schema.COLUMNS b
where
    a.TABLE_NAME = 'myTable'
    and b.TABLE_NAME = 'myTable'
    and CONVERT(int, substring(a.COLUMN_NAME, 2, len(a.COLUMN_NAME) - 1)) <=
        CONVERT(int, substring(b.COLUMN_NAME, 2, len(b.COLUMN_NAME) - 1))
order by
    CONVERT(int, substring(a.COLUMN_NAME, 2, len(a.COLUMN_NAME) - 1)),
    CONVERT(int, substring(b.COLUMN_NAME, 2, len(b.COLUMN_NAME) - 1))


--print @sql

insert into #temp(Name,Value)
EXEC sp_executesql @sql


--drop table #temp
