foreign key referring to same table is not supported..

Hi Everyone,

Trying to create a foreign key referring to the primary key of same table. But prompted with, feature not supported: cannot create foreign key constraint referring to the same table.

Is it possible to create this link by any other means...

Please go through below syntax:

CREATE COLUMN TABLE "NEO_xxxxx"."C_EMPLOYEES" ("EMPLOYEENUMBER" INTEGER CS_INT NOT NULL ,

  "LASTNAME" NVARCHAR(50) NOT NULL ,

    "REPORTSTO" NVARCHAR(50)  NULL ,

  PRIMARY KEY ("EMPLOYEENUMBER"));
