Authorizer Return Codes

#define SQLITE_DENY   1   /* Abort the SQL statement with an error */
#define SQLITE_IGNORE 2   /* Don't allow access, but don't generate an error */

The authorizer callback function must return either SQLITE_OK or one of these two constants in order to signal SQLite whether or not the action is permitted. See the authorizer documentation for additional information.

Note that SQLITE_IGNORE is also used as a conflict resolution mode returned from the sqlite3_vtab_on_conflict() interface.
