Question

I’m trying to update a table via a stored procedure from asp.net. I get the following error message: “wrong number or types of arguments in call to ‘UPDATE_DIRECT_BILL_DETL_SP'”

I just can’t seem to figure out what is wrong. I believe I may not be using the correct Oracle variable types in my Cmd.Parameter.Add statements.

I appreciate any help that can be provided!

Thank you.

Here are the details:

I’m using Oracle.DataAccess.dll (ODP.NET)

Here is my function:

Public Function UpdateDirectBill(ByVal invDetID As Int32, ByVal appNum As String, _
             ByVal lastUpdtByNm As String) As Int32

    Dim numRecUpdated As Int32 = 0

    Cmd.CommandType = CommandType.StoredProcedure
    Cmd.CommandText = "UPDATE_DIRECT_BILL_DETL_SP"

    'These are the values I'm using for the params
    invDetID = 1
    appNum = "3333"
    lastUpdtByNm = "N015058"

    Cmd.Parameters.Add("invDetID", OracleDbType.Int32,    invDetID,   ParameterDirection.Input)
    Cmd.Parameters.Add("appNum",   OracleDbType.Varchar2, appNum,        ParameterDirection.Input)
    Cmd.Parameters.Add("lastUpdtByNm",  OracleDbType.Varchar2, lastUpdtByNm,  ParameterDirection.Input)
    Cmd.Parameters.Add("numRecUpdated", OracleDbType.Int32,    numRecUpdated, ParameterDirection.Output)

    Conn.Open()
    Cmd.ExecuteNonQuery()
    Conn.Close()

    Dim recsUpdated As Int32 = Convert.ToInt32(Me.Cmd.Parameters("numRecUpdated").Value.ToString())

    Return recsUpdated
End Function

My Stored Procedure:

  PROCEDURE UPDATE_DIRECT_BILL_DETL_SP
  (invDetID     IN invoice_detail.invoice_detail_id%TYPE,
   appNum       IN invoice_detail.application_num%TYPE,
   lastUpdateNm IN invoice_detail.last_update_by_nm%TYPE, 
   rowCnt       OUT number)
  IS
  BEGIN 
    UPDATE INVOICE_DETAIL A
    SET
    A.APPLICATION_NUM=appNum,
    A.LAST_UPDATE_BY_NM = lastUpdateNm, 
    A.LAST_UPDATE_BY_DT=SYSDATE
    WHERE A.INVOICE_DETAIL_ID=invDetID;

    rowCnt := SQL%ROWCOUNT;
    if rowCnt = 1 then
      COMMIT;
    ELSE
      ROLLBACK;
    END IF;
  END UPDATE_DIRECT_BILL_DETL_SP;

The columns I’m updating are of the following types:

   invDetID IN invoice_detail.invoice_detail_id%TYPE        of type Number
   appNum in invoice_detail.application_num%TYPE            of type Varchar2(10 byte)
   lastUpdateNm IN invoice_detail.last_update_by_nm%TYPE    of type Varchar2(50 byte)

Your parameter names don’t match up ‘rowCnt’ and ‘numRecUpdated’. Also you’re specifying the type as Int in your call, but the stored proc specifies it as a Number which maps to a Decimal. So you would need to specify it either as a OracleDbType.Decimal type rather than an int. Or change your stored proc parameter to an INTEGER http://download.oracle.com/docs/cd/B19306_01/win.102/b14307/OracleDbTypeEnumerationType.htm

Cmd.Parameters.Add("rowCnt", OracleDbType.Decimal, numRecUpdated, ParameterDirection.Output)
