error in saving

[amu]

Would you please help me because i am trying to save using oracle but i am coding with VB.net and my forms are designed using A.S.P.net.
the error is ORA-02291: integrity constraint (SCOTT.STUDENT_ INFOR_FK) violated - parent key not found
ORA-06512: at "SCOTT.ADD_STUD ENT_INFOR", line 4

i think its my stored procedures but i'm not sure

that is because you are trying to insert some record to a child table for which there is no parent key in the referenced parent table. It has nothing to do with .net . It is because of error in database design and the implemented logic in your code through the stored procedure.
