[Almoha]

Hi All,

i have the following data, for every on record i need to create two records with stdy and endy values populated under col1 and values in res must be populated under res1 as follows

any suggestions?

This is what i have 

sub stdy endy res
111 1 7 10
111 8 10 20
111 11 13 20
111 15 20 40
222 12 17 70
222 18 30 70

the final output
sub col1 res1
111 1 10
111 7 10
111 8 20
111 10 20
111 11 20
111 13 20
111 15 40
111 20 40
222 12 70
222 17 70
222 18 70
222 30 70
