Hi,

In a simple sentence, EJB-QL is a standard notation for expressing CMP query operations. I mean for quering the Container Managed Persistent Java Objects. SQL is the standard to query RDBMS.

I would advice you to take a look at Appendix D of Mastering EJB by ED Roman. This will give you a very clear insight in to what EJB-QL means and what operations you can do with EJB-QL.

Thanks
Shibu
