In the Below SP, I need to have the @month_value Select case dynamic for all the months of the year.

you dont need those CASE WHEN constructs if you already break logic by means of IF conditions

And they should have Numeric Data as well ... however requirements are still not clear

taking your first sample


if (@St_month=1)
Begin
set @month_value=( SELECT DISTINCT CASE WHEN @St_month between 1 and 1 then [january]
when @St_month between 1 and 2 then ([january]+[february])/2
when @St_month between 1 and 3 then ([january]+[february]+[march])/3
when @St_month between 1 and 4 then ([january]+[february]+[march]+[april])/4
when @St_month between 1 and 5 then ([january]+[february]+[march]+[april]+[may])/5
when @St_month between 1 and 6 then ([january]+[february]+[march]+[april]+[may]+[jun])/6
when @St_month between 1 and 7 then ([january]+[february]+[march]+[april]+[may]+[jun]+[july])/7
when @St_month between 1 and 8 then ([january]+[february]+[march]+[april]+[may]+[jun]+[july]+[august])/8
when @St_month between 1 and 9 then ([january]+[february]+[march]+[april]+[may]+[jun]+[july]+[august]+[septempber])/9
when @St_month between 1 and 10 then ([january]+[february]+[march]+[april]+[may]+[jun]+[july]+[august]+[septempber]+[october])/10
when @St_month between 1 and 11 then ([january]+[february]+[march]+[april]+[may]+[jun]+[july]+[august]+[septempber]+[october]+[november])/11
when @St_month between 1 and 12 then ([january]+[february]+[march]+[april]+[may]+[jun]+[july]+[august]+[septempber]+[october]+[november]+[december])/12
end from pricing_matrix )
end


this snip says that when @St_month=1 then check
1) if @St_month is betwen 1 and 1 (which is true)
2) if @St_month is betwen 1 and 2 (which is true)
N) if @St_month is betwen 1 and N (which is true)

so which one is desired? as all are getting true. hope you are getting my point.

Perhaps it would be better if you come up with your requirements in light of some sample data/records (provided in the form of Insert into statments) and desired output(explanation of the logic behind output). May be anyone from the team could come up with a better solution.

Cheers
MIK
