How would the developer do that? With the front-end I am working with
(ColdFusion MX) I have very little control over the actual calls to the
driver. I can make CF MX use createStatement() or prepareStatement() but
that is all the control I have. And the only way to send parameters to
the driver would be through a JDBC URL.
Would that enable me to use prepared statements for real or not?
