Answer 1

Though it's too late now and also the OP has an accepted answer, but still it's worth mentioning to read the article on Split Function in Sql Server using Set base approach where the author has shown many ways of achieving the same.

Answer 2

This one will work with empty strings

DECLARE @InputString VARCHAR(1000)
    SELECT @InputString = 'a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,,1'

    SELECT SUBSTRING(',' + @InputString + ',', Number + 1,
    CHARINDEX(',', ',' + @InputString + ',', Number + 1) - Number -1)AS VALUE
    FROM master..spt_values
    WHERE type = 'p'
    AND Number <= LEN(',' + @InputString + ',') - 1
    AND SUBSTRING(',' + @InputString + ',', Number, 1) = ','
    GO
