Sure Dave, here they are:
parent entity
{
attributes = (
{allowsNull = N; name = id; prototypeName = id; },
{allowsNull = Y; columnName = name; name = name; prototypeName =
varchar255; }
);
attributesUsedForLocking = (id);
className = "com.anazys.tempFrameworkWonder54.Core";
classProperties = (name);
fetchSpecificationDictionary = {};
isAbstractEntity = Y;
name = Core;
primaryKeyAttributes = (id);
}
subclass Employee
{
attributes = (
{allowsNull = N; name = id; prototypeName = id; },
{allowsNull = Y; columnName = name; name = name; prototypeName =
varchar255; }
);
attributesUsedForLocking = (id);
className = "com.anazys.tempFrameworkWonder54.Employee";
classProperties = (name);
externalName = Employee;
fetchSpecificationDictionary = {};
name = Employee;
parent = Core;
primaryKeyAttributes = (id);
}
subclass Customer
{
attributes = (
{allowsNull = N; name = id; prototypeName = id; },
{allowsNull = Y; columnName = name; name = name; prototypeName =
varchar255; }
);
attributesUsedForLocking = (id);
className = "com.anazys.tempFrameworkWonder54.Customer";
classProperties = (name);
externalName = Customer;
fetchSpecificationDictionary = {};
name = Customer;
parent = Core;
primaryKeyAttributes = (id);
}
I could edit the code for the SQL when generating the database, but the issue
is really in production, if I update the app, it will start to generate pk
based on the sub-entity, and I will end up with duplicate pks between various
sub-classes.
So the SQL generated by EntityModeler is just a way to check if it's going to
break the current app, not really for that specific action.
