 Description   

These scripts work fine in Oracle:

BEGIN
 
<<history>>
 
  NULL;
 
END;
 
/


BEGIN
 
<<system>>
 
  NULL;
 
END;
 
/


BEGIN
 
<<versioning>>
 
  NULL;
 
END;
 
/


BEGIN
 
<<without>>
 
  NULL;
 
END;
 
/

If I try equivalent scripts in MariaDB:

SET sql_mode=ORACLE;
 
DELIMITER /
 
BEGIN
 
<<history>>
 
  NULL;
 
END;
 
/
 
DELIMITER ;


SET sql_mode=ORACLE;
 
DELIMITER /
 
BEGIN
 
<<system>>
 
  NULL;
 
END;
 
/
 
DELIMITER ;


SET sql_mode=ORACLE;
 
DELIMITER /
 
BEGIN
 
<<versioning>>
 
  NULL;
 
END;
 
/
 
DELIMITER ;


SET sql_mode=ORACLE;
 
DELIMITER /
 
BEGIN
 
<<without>>
 
  NULL;
 
END;
 
/
 
DELIMITER ;

they fail, e.g.:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'history>>
