TSqlORMapperThis code example demonstrates the basic CRUD operations (create, read, update, delete) using TSqlORMapper. We create a mapper object and a Person object, set its properties, and use the insert() method to add it to the database. We then update() and remove() the object from the database. Finally, we fetch all rows from the Person table, prepare the mapper with the SQL query and iterate over all the items in the mapper using the next() method, and print out their properties. In conclusion, TSqlORMapper is a C++ ORM library that simplifies the interaction with SQL databases by mapping C++ classes to SQL tables and vice versa. Its package library streamlines the usage of ORM for C++ developers.mapper; Person person; person.setName("John Doe"); person.setBirthDate(QDate(1990, 1, 1)); mapper.insert(person); person.setId(1); person.setName("Jane Doe"); person.setBirthDate(QDate(1995, 6, 15)); mapper.update(person); mapper.remove(person); TSqlQuery q("SELECT * FROM Person"); q.exec(); mapper.prepare(q); while (mapper.next()) { Person person = mapper.current(); qDebug() << person.id() << person.name() << person.birthDate(); }
