Because, at the very least, if you run the same program with different parameters, then multiple statements are sent to the server, with different text. This means they have to be reparsed.

If you use placeholders, then, irrespective of the number of times the statement is executed, the database only ever gets one version of it, but with different parameters. So there's only one parse (which is both faster and more memory efficient for the server).
