Dag H. Wanvik commented on DERBY-3676:
--------------------------------------
I think the idea is this can only be done from code which can already access
the prepared statement (the session that set the arguments in the first place).
Presumably this would not be active in deployed code, but it should be used
with care, I agree.
> 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.
