 Description   

The keyword ELSEIF does not have a special meaning on Oracle. These scripts work fine on Oracle:

DECLARE
 
  ELSEIF INT;
 
BEGIN
 
  ELSEIF:=1;
 
END;
 
/


BEGIN
 
<<ELSEIF>>
 
  NULL;
 
END;
 
/

Equivalent MariaDB scripts produce systax errors:

SET sql_mode=ORACLE;
 
DELIMITER /
 
DECLARE
 
  ELSEIF INT;
 
BEGIN
 
  ELSEIF:=1;
 
END;
 
/
 
DELIMITER ;


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 'ELSEIF INT;...


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