Calling a procedure in C# with parameters

[Derek Lansing]

I am trying to call a stored procedure in version 5 beta from a C# program. My stored procedure is:

CREATE PROCEDURE `oib2b_test`.`Trace_LogRequest`(_Username varchar(255),
_AccessDateTime datetime,
_MethodCalled varchar(255),
_IPAddress varchar(50),
_XMLIn varchar(255))
BEGIN
insert into trace values(_Username, _AccessDateTime, _MethodCalled, _IPAddress, _XMLIn);
END




I am calling it with this code:

public override bool AddTraceToLog(string username, DateTime accessDateTime, string methodCalled, string ipAddress, string xmlIn)
{
MySqlCommand MySqlCmd = new MySqlCommand();

AddParamToMySqlCmd(MySqlCmd, "_ReturnValue", MySqlDbType.Int16, 0, ParameterDirection.ReturnValue, null);
AddParamToMySqlCmd(MySqlCmd, "_Username", MySqlDbType.VarChar, 255, ParameterDirection.Input, username);
AddParamToMySqlCmd(MySqlCmd, "_AccessDateTime", MySqlDbType.Datetime, 0, ParameterDirection.Input, accessDateTime);
AddParamToMySqlCmd(MySqlCmd, "_MethodCalled", MySqlDbType.VarChar, 255, ParameterDirection.Input, methodCalled);
AddParamToMySqlCmd(MySqlCmd, "_IPAddress", MySqlDbType.VarChar, 50, ParameterDirection.Input, ipAddress);
AddParamToMySqlCmd(MySqlCmd, "_XMLIn", MySqlDbType.VarChar, 0, ParameterDirection.Input, xmlIn);

SetCommandType(MySqlCmd,CommandType.StoredProcedure, SP_TRACE_LOGREQUEST);
ExecuteScalarCmd(MySqlCmd);
int returnValue = (int)MySqlCmd.Parameters["_ReturnValue"].Value;
return (returnValue == 0 ? true : false);
}



I am getting an error of:

Server was unable to process request. --> #42000Incorrect number of arguments for PROCEDURE oib2b_test.Trace_LogRequest; expected 5, got 1



I don't know what I am doing wrong. If anyone could help me, it would be greatly appreciated. I know that the user I am using has the permissions to access the db because I've already had that error.

Thank you.
