      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 ;
