    Discriminator Column in Joined Inheritance Strategy?

    rabbiaqaswar

      Hi

      Can anyone please tell me how to use the Discriminator Column in queries when using the Joined strategy for Inheritance?

      I have three database tables, Employee, PartTimeEmployee and FullTimeEmployee.
      For these tables i have three entities, abtract parent class Employee having two subclass entities i.e. PartTimeEmployee & FullTimeEmployee. The name of discriminator column in Employee is ETYPE.

      Now if i want to run a query in which i want to get all the PartTimeEmployee from the Employee table, how can i use the ETYPE column to differentiate between the two types of Employees so that i only get all the PartTimeEmployees?

      Thanks
