here's my code but it's not right:

create procedure tapesid
@columnname varchar
AS
begin
select @columnname from tapes
end 
exec tapesid 'title'

You've tagged this as MySQL , so... here's a stored procedure, though it's unclear from your example what you're really wanting it to do or why.

The variables passed into a stored procedure as arguments don't use '@' in front of them.

DELIMITER $$

CREATE PROCEDURE list_tspec_id (IN my_title VARCHAR(254))
BEGIN

  SELECT TapesID, Title, Qty FROM Tapes WHERE Title = my_title;

END $$
DELIMITER ;

then...

mysql> CALL list_tspec_id('BatDog');
