In 12c puoi usare la row_limiting_clause, documentata qui:http:// docs.oracle.com/database/121/SQLRF/statements_10002.htm#SQLRF01702
La sintassi generale è:
[ OFFSET offset { ROW | ROWS } ]
[ FETCH { FIRST | NEXT } [ { rowcount | percent PERCENT } ]
{ ROW | ROWS } { ONLY | WITH TIES } ]
In alternativa, utilizza l'API Oracle Streams Advanced Queuing documentata qui:http:/ /docs.oracle.com/database/121/ADQUE/aq_opers.htm#ADQUE2835
