42000 Error ODBC driver for Oracle Syntax error or access violation

Hi,

I have a simple Oracle stored procedure:

CREATE OR REPLACE procedure DEV.SL_CLOB_TEST(numId1 IN PLS_INTEGER,id IN PLS_INTEGER, strText IN CLOB)
as
begin
insert into test_table
values (numId1,id, strText, sysdate, user);
end;
/

And I have a client .net code to use ODBC.NET

class Program
{
static void Main(string[] args)
{
string connectionString = "Driver={Microsoft ODBC for Oracle};Server=servername;Uid=myusername;Pwd=mypassword";
var connection = new OdbcConnection(connectionString);
connection.Open();

IDbCommand command = connection.CreateCommand();

command.CommandText = "{call SL_CLOB_TEST(?,?,?)}";
command.CommandType = CommandType.StoredProcedure;

OdbcParameter parameter1 = new OdbcParameter("NUMID1", OdbcType.Int);
parameter1.Value = 123;
parameter1.Direction = ParameterDirection.Input;
command.Parameters.Add(parameter1);

OdbcParameter parameter2 = new OdbcParameter("ID", OdbcType.Int);
parameter2.Value = 234;
parameter2.Direction = ParameterDirection.Input;
command.Parameters.Add(parameter2);

OdbcParameter parameter3 = new OdbcParameter("STRTEXT", OdbcType.VarChar);
parameter3.Value = getClob();
parameter3.Direction = ParameterDirection.Input;
command.Parameters.Add(parameter3);

command.ExecuteNonQuery();
}

private static string getClob()
{
return new string('a', 10);
}
}

When I ran it I got ERROR [42000] [Microsoft][ODBC driver for Oracle]Syntax error or access violation, the whole call stack is

System.Data.Odbc.OdbcException was unhandled
Message=ERROR [42000] [Microsoft][ODBC driver for Oracle]Syntax error or access violation

Anybody could point out what is wrong with my .Net code?
