For security reasons I normally use placeholders in the select statements I execute via DBI (using MySQL).

I'm working on a routine that requires a select statement that looks like this:
SELECT * FROM catalog WHERE item_id='ABC1' OR item_id='EFG2'
The actual statment might need more item_id's. In any case, I can't use a placeholder since they must represent a single value. I can, of course, build the query as a string by tacking on the items I want from @items_to_include but that raises all the issues that drive prudent developers to use place holders in the first place. Besides, it leads to very ugly looking code.

Executing multiple select statements for the sake of using placeholders would be inneficient. Is there an alternative idiom for using OR in a WHERE clause I'm not aware of?

Your help would be most appreciated.
