Oracle.DataAccess.Client.OracleException ORA-06502: PL/SQL

Question

I have the following Simple PL/SQL function:
FUNCTION INSERTFBEXP (
p_expid INTEGER,
p_run_identifier     VARCHAR2,
p_run_complete     INTEGER,
p_run_completion_status VARCHAR2,
p_complete_errors INTEGER
RETURN INTEGER
IS
newid INTEGER;
concheck INTEGER;
BEGIN
concheck := 1;
newid := 1;
INSERT INTO test.exp
(ID, concheck, expid, run_identifier,run_complete, run_completion_status, complete_errors
VALUES (test.id_testexp.NEXTVAL, concheck, p_expid, p_run_identifier, p_run_complete, p_run_completion_status, p_complete_errors
) RETURNING ID INTO newid;
RETURN newid;
END;
Which I am calling from the following .Net procedure:
Public Function insertTestExp(ByVal expid As Int32, ByVal Run_Identifier As String, _
ByVal Run_Complete As Boolean, ByVal CompletionStatus As String, ByVal Complete_Errors As Boolean) As Integer
Dim id As Integer
With m_OraCmd
.CommandText = "USER.FBPROCESS.INSERTFBEXP"
.CommandType = CommandType.StoredProcedure
With .Parameters
.Clear()
.Add(New OracleParameter("p_expid", OracleDbType.Int32)).Value = expid
.Add(New OracleParameter("p_run_identifier", OracleDbType.Varchar2, 50)).Value = Run_Identifier
.Add(New OracleParameter("p_run_complete", OracleDbType.Int32)).Value = Convert.ToInt32(Run_Complete)
.Add(New OracleParameter("p_run_completion_status", OracleDbType.Varchar2, 50)).Value = CompletionStatus
.Add(New OracleParameter("p_complete_errors", OracleDbType.Int32)).Value = Convert.ToInt32(Complete_Errors)
.Add(New OracleParameter("newid", OracleDbType.Int32)).Direction = ParameterDirection.ReturnValue
End With
Try
.ExecuteNonQuery()
Catch ex As Exception
MsgBox(ex.ToString)
End Try
Return CType(.Parameters(5).Value, Int32)
End With
End Function
When I attempt to run the .Net function I get the following error:
Oracle.DataAccess.Client.OracleException ORA-06502: PL/SQL
I have determined by trial and error that the problem is in passing the VARCHAR2 parameters. I do not have this problem with the Microsoft Oracle Provider. Can someone help me with what I'm missing? Thanks.

Answer 1

Note that I have not tested your code... but, it looks like you are using bind by position (which is the default). In this mode the return value needs to be bound first since ODP.NET will generate code similar to this:
:ret_val := proc(:1, :2,...);That's where I would start anyway.
Hope that helps a bit,
