Need to list ABC2001 as 2001 some times ABCD2001 as 2001 .
alter function NoLetters(@string2number varchar(200)) returns varchar(200)
as
begin
declare @c int
declare @num varchar(200)
set @num = ''
declare @txtCurrent char(1)
set @c=1
while @c<=len(@string2number)
begin
set @txtCurrent = substring(@string2number,@c,1)
if ascii(@txtCurrent) between 48 and 57
set @num = @num + @txtCurrent
set @c=@c+1
end
return @num
end
