Hi,
I got this one base class which is been inherited by other classes. When I execute select on the base class A select query is fired on the inherited class also.
And moreover the select is also fired on the classes which have relationship with the derived class
Can somebody help me with this
regards
prasad

I think you should read the doc ;-)
Have a look at polymorphism attribute.
Have a look at lazy=true attribute
Have a look at proxy attribute
