Member Function Documentation

◆ do_abort()

void pqxx::dbtransaction::do_abort ( )

protectedvirtual

Sensible default implemented here: abort backend transaction.

Default implementation does two things:

Clears the "connection reactivation avoidance counter"
Executes a ROLLBACK statement

Implements pqxx::transaction_base.

Referenced by pqxx::basic_robusttransaction::~basic_robusttransaction().

◆ do_begin()

void pqxx::dbtransaction::do_begin ( )

protectedvirtual

Sensible default implemented here: begin backend transaction.

Implements pqxx::transaction_base.

References pqxx::transaction_base::conn(), and pqxx::transaction_base::DirectExec().

◆ do_commit()

virtual void pqxx::dbtransaction::do_commit ( )

To be implemented by derived class: commit backend transaction.

Implements pqxx::transaction_base.

◆ do_exec()

pqxx::result pqxx::dbtransaction::do_exec ( const char Query[] )

protectedvirtual

Sensible default implemented here: perform query.

Implements pqxx::transaction_base.
