Rick Hillegas commented on DERBY-3676:
--------------------------------------
Do we understand the use case for this change to the toString() method? The
original email thread doesn't indicate why users want this feature. Is it for
development/debugging purposes or is there a production use case?
In other email threads, I see development/debugging needs for this toString()
behavior. See for instance
http://www.javakb.com/Uwe/Forum.aspx/java-databases/1003/PreparedStatement-toString
For that use case, there seem to be some freeware workarounds. See
http://code.google.com/p/jdbc-trace-wrapper/ and
http://www.javaworld.com/javaworld/jw-01-2002/jw-0125-overpower.html
Thanks,

> 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.
