[Firebird-odbc-devel] IMplementation for SQLNumParams

[Carlos G.A. <car...@ho...>]

Hello:

I made the implementation for SQLNumParams here is the code:


Main.cpp

///// SQLNumParams /////

RETCODE SQL_API SQLNumParams  (HSTMT arg0,
		 SWORD * arg1)
{
	/*
	notYetImplemented("SQLNumParams called\n");
	return(SQL_SUCCESS);
	*/

	TRACE("SQLMoreResults");

	return ((OdbcStatement*) arg0)->sqlNumParams(arg1);
}



OdbcStatement.h

New declaration

RETCODE sqlNumParams (SWORD *params);

OdbcStatement.cpp

New definition

RETCODE OdbcStatement::sqlNumParams(SWORD * params)
{
	clearErrors();

	if (statement)
		try
			{
			*params = statement->getNumParams();
			}
		catch (SQLException& exception)
			{
			postError ("HY000", exception);
			return SQL_ERROR;
			}
	else
		*params = 0;

	return sqlSuccess();
}


IscConection.h

New declaration in class PreparedStatement : public Statement

virtual	int			getNumParams() = 0;


IscPreparedStatement.h

New declaration

virtual int			getNumParams();


IscPreparedStatement.cpp

New definition

int IscPreparedStatement::getNumParams()
{
	return parameters.count;
}



IscCallableStatement.h

New declaration

virtual	int			getNumParams();

IscCallableStatement.cpp

New definition

int	IscCallableStatement::getNumParams()
{
	return Parent::getNumParams();
}
