ROWNUM
For each row returned by a query, the ROWNUM pseudocolumn returns a
number indicating the order in which Oracle selects the row from a table
or set of joined rows. The first row selected has a ROWNUM of 1, the
second has 2, and so on. You can use ROWNUM to limit the number of rows
returned by a query, as in this example:
 SELECT * FROM emp WHERE ROWNUM < 10;

dalsi viz dokumentace Oracle...

P.S. Cisla rownum jsou radkum prirazovana "az po vyberu", tzn.
zmenite-li napr. klauzuli order, budou jinak i cisla rownum. Nelze proto
pouzit podminku rownum = 35, protoze ta nebude splnena nikdy...
