The SQL Server return value parameter is called @RETURN_VALUE, not RetCd. (at least that is the case for SqlClient)
Morty -----Original Message----- From: tim [mailto:[EMAIL PROTECTED]] Sent: Friday, August 16, 2002 1:17 AM To: [EMAIL PROTECTED] Subject: [ADVANCED-DOTNET] Hi all, I am having a problem invoking a Stored Procedure via OleDbCommand - Receiving error "Too many arguments specified". I have a SQL Server 2000 stored procedure defined as follows: CREATE PROCEDURE ST_USER_INS @Name varchar(27), @System_User_Id varchar(20), @Location_Id int, @Created_By_Id int, @Id int OUTPUT, @ErrMsg varchar(100)='' OUTPUT AS IF @Location_Id <= 0 SET @Location_Id = NULL INSERT INTO T_USER ( Status_Cd, Name, System_User_Id, Location_Id, Created_By_Id, Created_Dtm ) VALUES ( 'A', @Name, @System_User_Id, @Location_Id, @Created_By_Id, getdate() ) SELECT @Id=@@IDENTITY RETURN 0 Note there are 4 input parameters, 2 output parameters, and the return value. I am using the OLE DB Provider for SQL Server to access. The reason I am not using the SQL managed provider is because the database will shortly be migrated to a Oracle, and I intend to use the Oracle OLE DB Provider by just changing the connection string (Yes, I know there is an Oracle managed provider, but I'm not currently planning on using this, as performance will not be super-critical for this app). Here is the code I invoke it with: moCmd = New OleDbCommand() moCmd.Connection = moCn moCmd.CommandText = "st_User_INS" moCmd.CommandType = CommandType.StoredProcedure '--- build the parameters moCmd.Parameters.Add("Name", OleDbType.VarChar, 27) moCmd.Parameters("Name").Value = msName moCmd.Parameters.Add("System_User_Id", OleDbType.VarChar, 20) moCmd.Parameters("System_User_Id").Value = msSystemUserId moCmd.Parameters.Add("Location_Id", OleDbType.Integer, 4) moCmd.Parameters("Location_Id").Value = mlLocationId moCmd.Parameters.Add("Created_By_Id", OleDbType.Integer, 4) moCmd.Parameters("Created_By_Id").Value = clsUtilities.CurrentUser.UserId '--- output parameters moCmd.Parameters.Add("Id", OleDbType.Integer, 4) moCmd.Parameters("Id").Direction = ParameterDirection.Output moCmd.Parameters.Add("RetCd", OleDbType.Integer, 4) moCmd.Parameters("RetCd").Direction = ParameterDirection.ReturnValue moCmd.Parameters.Add("ErrMsg", OleDbType.Char, 100) moCmd.Parameters("ErrMsg").Direction = ParameterDirection.Output moCmd.ExecuteNonQuery() moCmd.Parameters("ErrMsg").Direction = ParameterDirection.ReturnValue lRetCd = moCmd.Parameters("RetCd").Value I receive an exception indicating: System.Data.OleDb.OleDbException: Procedure or function ST_USER_INS has too many arguments specified... blah blah blah If I comment out the lines that define the "RetCd" parameter, it works fine (except of course I can't get the return value). It seems as though the Ole DB provider mistreats a ReturnValue as an Input or Output parameter ? I swear this works fine with the SQL managed provider. I searched on Microsoft, google, and the archives and didn't find any mention of this problem. Any input is appreciated.
