Hi Pradeep,

for better understanding of PERSISTENT object and persistent classes, please see this link.

As far as i concern the method GET_PERSISTENT_BY_QUERY( ) does a SELECT * on the table for which the Persistent mapping has been defined. So you have not to use select queries each time using persistent

classes.

For better references , please see this link
