Detailed Description

A simple transaction guard implementing RAAI for savepoints. Savepoints can be used recursively.

Example

sqlite::connection conn;
conn.connect("./my-database.db");
 
sqlite::savepoint t{conn, "my-savepoint};
conn.prepare("insert into log (text) values ($1)").execute(std::make_tuple("booting up"));
t.commit();
