To uz musite nejak obejit v aplikaci, napriklad pouzijete 
SELECT * FROM tabulka WHERE rownum < 10
a potom prvnich 5 radku ve smycce preskocite.
Take muzete zkusit neco takoveho:
SELECT * FROM tabulka WHERE rownum < 10 MINUS SELECT * FROM tabulka
WHERE rownum < 5;

Zalezi jen na Vas...

Obavam se, ze limit z mysql neni obsazen v definici sql. Stejne muzeme
plakat, ze mysql nema xxxxx a Oracle ano...
