This goes against what SQL is. A SELECT statement returns a SET of values with no especial rank, i.e. the sequence is not guaranteed. If you want only to see a certain subset you have to define this as part of the WHERE clause. It seems that you are trying to make a set oriented language (4GL) operate in a sequential (3GL) manner, which isn't in the nature of the beast.
