From your example it looks like you want the distinct values from the table

SELECT DISTINCT COL_NAME1, COL_NAME2 FROM...

But I doubt that is it. What exactly do you need?

Use distinct keyword? Sample

If those columns are the extent of your fields in the table, why allow duplicates in the first place? In any event, you may be better off storing the ids (maybe integers) if these fields are foreign keys.

I think the problem is the way I designed my table it is all wrong thanks guys it feels good to have friends who will help if even they can't thanks this is a family

SELECT site, DISTINCT cat FROM tablename;
Change tablename to the name of table you are using.
