A related problem:

This script erroneously return a result, it should return an error instead,
as it mixes ROW and scalar expressions in the INTERVAL function:

SET sql_mode=DEFAULT;
 
DELIMITER $$
 
BEGIN NOT ATOMIC
 
  DECLARE v ROW(a INT);
 
  SELECT INTERVAL(v,'a','b');
 
END $$
 
DELIMITER ;


+---------------------+
 
| INTERVAL(v,'a','b') |
 
+---------------------+
 
|                  -1 |
 
+---------------------+
