Mark B updated DERBY-3676:
--------------------------
Attachment: humanstringprepared.txt
Hi I noticed the request is marked as suitable for a newbie so I've made a
preliminary patch;
I'd make these comments
1 I tend to feel that the idea of making the toString() method return the sql,
then documenting a change so that a new method, let's say idString() returned
the original toString() id, is more appropriate
2 as currently written, there is no checking for thread-safety
3 a quoted '?' in the PreparedStatement would be replaced, so the replacement
routine should be improved
4 I should add client-side / api functionality, as well as Embedded
currently it works as suggested in a cast to ((EmbedPreparedStatement)
ps).toHumanString()
I'm just posting the patch for comments / to avoid duplication of work so
people notice I'm working at it
> 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.
