Hi all,
I'm creating a BMP enitybean. I'm confused about the correct way of coding
ejbFindBy & ejbLoad
If I code as below, the number of select statements fired to database is
equal to the number of number of primary keys returned by ejbFindBy
Enumeration ejbFindByXXX( y )
{
execute select .. from abc where x=y
return listOf primaryKeys;
}
ejbLoad()
{
execute select .. from abc where primaryKey=primaryKey.value
}
--------------------------
Instead I want do everything in one query, so I want to do something like
below
Enumeration ejbFindByXXX( y )
{
execute select .. from abc where x=y
create entity beans from the result and add to container
return listOf primaryKeys;
}
ejbLoad()
{
don't do anything
}
Now the doubt is how do I create new entity bean, I don't think I can do new
MyBean(), is there anyway using EJBHome or EntityContext I can achieve this.
If this is not possible, isn't the Entity Bean concept has some serious
performance problem, where as the traditional jdbc program can do this is in
one query?
