Mark B commented on DERBY-3676:
-------------------------------
Hi Rick,
I've now addressed that quoted '?' business;
I'm adding the client functionality now;
the only real 'policy' question now is how to handle quotes - a string
substitution should be quoted, while a null substitution should perhaps not be;
I need to look into the public API aspect, I'm just picking up the feel for the
way the code is arranged; the suggestions sound good though
I'll post the patch when it's virtually complete rather than as a regular update
> Make the toString() method of Derby PreparedStatements print out SQL text
> with ? parameters replaced by the values that have been set so far

> This topic came up in the following email thread on the user list:
> http://www.nabble.com/PreparedStatement.toString%28%29---nice-formatting-td17250811.html#a17250811
> Here's what the thread requests:
> "In mysql, a toString() on a PreparedStatement will do this, eg "select x
> from foo where x.a = ?" will become "select x from foo where x.a = 1" with
> the appropriate setValue() call."
> At first blush, this seems like it might be a simple project for a newcomer.
