Connect to Database

All you need to start using oatpp ORM with PostgreSQL is to create oatpp::postgresql::Executor and provide it to your DbClient.

#include"db/MyClient.hpp"
#include"oatpp-postgresql/orm.hpp"classAppComponent {
public:/** * Create DbClient component.*/OATPP_CREATE_COMPONENT(std::shared_ptr<db::MyClient>, myDatabaseClient)([] {
/* Create database-specific ConnectionProvider */auto connectionProvider = std::make_shared<oatpp::postgresql::ConnectionProvider>("<connection-string>"); /* Create database-specific ConnectionPool */auto connectionPool = oatpp::postgresql::ConnectionPool::createShared(connectionProvider, 10/* max-connections */, std::chrono::seconds(5) /* connection TTL */);
/* Create database-specific Executor */auto executor = std::make_shared<oatpp::postgresql::Executor>(connectionPool);
/* Create MyClient database client */return std::make_shared<MyClient>(executor);
}());
};
