C++ (Cpp) CLOB Examples

Example #1

File: Extractor.cpp Project: babafall/Sogeti-MasterThesis-CrossPlatformMobileDevelopment

bool Extractor::extract(std::size_t pos, Poco::Data::CLOB& val)
{
	if (_metadata.columnsReturned() <= pos)
		throw MySQLException("Extractor: attempt to extract more paremeters, than query result contain");
	
	if (_metadata.isNull(static_cast<Poco::UInt32>(pos)))
	return false;
	
	if (_metadata.metaColumn(static_cast<Poco::UInt32>(pos)).type() != Poco::Data::MetaColumn::FDT_BLOB)
		throw MySQLException("Extractor: not a blob");
	
	val.assignRaw(reinterpret_cast<const char*>(_metadata.rawData(pos)), _metadata.length(pos));
	return true;
}

Example #2

void Binder::bind(std::size_t pos, const Poco::Data::CLOB& val, Direction dir)
{
    poco_assert(dir == PD_IN);
    realBind(pos, MYSQL_TYPE_BLOB, val.rawContent(), static_cast<int>(val.size()));
}

Example #3

File: Binder.cpp Project: Kampbell/poco

void Binder::bind(std::size_t pos, const Poco::Data::CLOB& val, Direction dir, const WhenNullCb& nullCb)
{
	poco_assert(dir == PD_IN);
	realBind(pos, Poco::Data::MetaColumn::FDT_CLOB, &val, static_cast<int>(val.size()));
}
