** [prepared statement] statement is constructed to substitute
** a NULL value in place of the table column that would have
** been read if [SQLITE_OK] had been returned.  The [SQLITE_IGNORE]
** return can be used to deny an untrusted user access to individual
** columns of a table.
** ^When a table is referenced by a [SELECT] but no column values are
** extracted from that table (for example in a query like
** "SELECT count(*) FROM tab") then the [SQLITE_READ] authorizer callback
** is invoked once for that table with a NULL column name.
** ^If the action code is [SQLITE_DELETE] and the callback returns
** [SQLITE_IGNORE] then the [DELETE] operation proceeds but the
** [truncate optimization] is disabled and all rows are deleted individually.
