Let's say you try to get information from a line with a unique ID that doesn't exist in SQLite. It creates an error and causes big problems with my application. Would there be a way to return a nice error message instead? In context: Gecko uses a unique ID to get application info from an SQLite database and uses this information to either get an application based on a command and close (command line mode) or display the information and offer options (user-friendly mode). If it creates an error, it can start a chain reaction and cause more problems.
