The sqlite3_set_authorizer() interface registers a callback function that is invoked to authorize certain SQL statement actions. The second parameter to the callback is an integer code that specifies what action is being authorized. These are the integer action codes that the authorizer callback may be passed.

These action code values signify what kind of operation is to be authorized. The 3rd and 4th parameters to the authorization callback function will be parameters or NULL depending on which of these codes is used as the second parameter. The 5th parameter to the authorizer callback is the name of the database ("main", "temp", etc.) if applicable. The 6th parameter to the authorizer callback is the name of the inner-most trigger or view that is responsible for the access attempt or NULL if this access attempt is directly from top-level SQL code.
