HI,

how      1  1  1   3
are      0  0  2   2
you      0  1  0   1

i want to retrieve only columns count where the name starts with D so form the above table the result should be 3 please help.

Answer 1

SELECT
    Keyword, D1, D2, D3, D1 + D2 + D3 AS Total
FROM
    MyTable

You know the 3 columns starting D already: it’s inane to do it dynamically in case you add a new column D4
