I cant figure out what this means **Id not set on Entity**

[wlandgraf (Wagner Landgraf)]

Hi @Rohit_Nz, possible reason is an id with value 0. A quick search of the error in our Support Center brings several topics:

ID not set on entity class

One common reason is that you have a record in table T_GRADE where the value of column ID is zero. 

IdNotSetException

That is not a bug, but a desired behavior. Zero is considered a null id. When you have an object with a property Id: Integer, it's the way Aurelius tell that such class is transient and needs to be inserted and get a new id (or that the class doesn't have an id yet and generate an error if it's not auto generated). There is an undocumented attribute named IdUnsvedValue that you can use to work around that. That attributes allow you to change the default "null id" value, which is 0 by default: …

ID not set on entity class and sequencer definitions

You can. Use the IdUnsavedValue attribute to set a default 'unsaved id' different from zero. [Entity] [IdUnsavedValue(-1)] // <-- insert this line. [Table('employee')] [Description('')] [Sequence('employee_id_seq')] [Id('FId', TIdGenerator.IdentityOrSequence)] TEmployee = class(TMoonshineObject) (***) HTH,
