I get a SegFault with the main method below which uses HibernateD
. The second main method which uses ddbc just works fine. What is
wrong with the first main method ? I have attached the error at
the bottom although I don't think it says much.
This method uses HibernateD
int main() {
// setup DB connection
string url = MySQLDriver.generateUrl("localhost", 3306, "test");
string[string] params = MySQLDriver.setUserAndPassword("test",
"test");
DataSource ds = new ConnectionPoolDataSourceImpl(new
MySQLDriver(), url, params);
// create metadata from annotations
EntityMetaData schema = new SchemaInfoImpl!(Preferences);
// create session factory
Dialect dialect = new MySQLDialect();
SessionFactory factory = new SessionFactoryImpl(schema, dialect,
ds);
scope(exit) factory.close();
auto conn = ds.getConnection();
scope(exit) conn.close();
// create session
Session sess = factory.openSession();
scope(exit) sess.close();
Query q = sess.createQuery("select p from Preferences p");
Preferences[] list = q.list!Preferences();
return 0;
}
The method below uses ddbc.
int main(string[] args) {
string url =
"mysql://localhost:3306/test?user=test,password=test";
// creating Connection
auto conn = createConnection(url);
scope(exit) conn.close();
// creating Statement
auto stmt = conn.createStatement();
scope(exit) stmt.close();
// reading DB
auto rs = stmt.executeQuery("SELECT * FROM preferences_wm
ORDER BY id");
writeln(rs.getFetchSize());
return 0;
}
This is the error.
