◆ compileAssertion() [1/2]

virtual bool rdbModel::Connection::compileAssertion ( const Assertion a,
std::string &  sqlString

◆ dbRequest() [1/2]

virtual ResultHandle * rdbModel::Connection::dbRequest ( const std::string &  request)
pure virtual

Transmit raw request of any form to database. If it is a request that returns results, those results will be stored in a newly- allocated ResultHandle and dbRequest will return a pointer to it. Otherwise dbRequest will return a null pointer. Throw an exception if request fails for any reason.

Implemented in rdbModel::MysqlConnection, and rdbModel::MysqlConnection.

◆ dbRequest() [2/2]

virtual ResultHandle * rdbModel::Connection::dbRequest ( const std::string &  request)
