dual access

Hello Exploring the product having had significant experience win Kodo/BEA/JDO1.x, yes I know dated but still works.  Is it possible to still have the SQL emitted from only the JAVA syntax?  If so is it also possible get each SQL statement before it is sent to the store?  Does objectdb only permit direct SQL coding? #1 2012-02-24 02:39 Hello Exploring the product having had significant experience win Kodo/BEA/JDO1.x, yes I know dated but s ...

Queries are slow on a large database
