hi every one i have a atable like such and many things to do on it, since i am new to sql and i know how important it is, i want you please to help if you see me posting again and agian dont get bored with me please, i ll be posting my attempts and whoever wants can help me, as a first task i want to "Produce total sales per Product Group,per year"the product group is the middle numbers as '50' for the first one '25for the second, so i thought those must be distinct since they are the key so i made the following:

select to_char(ORD_DATE,'yyyy'),distinct( substr (PROD_CODE,3,2)), ((QTY*UNIT_PRICE)+SHIP_COST) from TABLE,

but this doesnt do the job becoz it wont give me the distinct values but duplicates and thats what i want
you see my attempt can u help me?
