How can I detect a query is wrong?

[Steven Van Ingelgem]

  Connection conn(false);
  conn.connect(database, hostname, username, password);
  Query qry = conn.query("SELECT BLABLABAL FROM "+table);
  ... Neither .use() nor .store() throws an exception or tells me something
went wrong in there...

The query is SQL correct, it just uses the wrong field from the table.


Thanks!
