Subject [jira] Commented: (DERBY-3676) Make the toString() method of Derby PreparedStatements print out SQL text with ? parameters replaced by the values that have been set so far
Date Tue, 20 May 2008 15:30:55 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598326#action_12598326

mike bell commented on DERBY-3676:
----------------------------------

Thanks for Ricks comments. 

Some replies

1. I must embarassedly admit (I thought I had been clear, but  I wasn't!) I DID NOT actually
manage to get a build of derby, a building. My test was merely to make a mock object, which
is of course inadequate in the end. I have no idea if I'll ever have time to get through the
durn building process, since um, regular work calls. That was a late night "treat" for me
after 16 hours of work. I'm pretty sure I can generate the diff regardless, but of course
I wouldn't except a patch without the contributor running the unit tests either.

2. As a consequence I guess I've missed something obvious - this would have been a Patch to
PreparedStatement.java. I'm not quite  following yours and Knuts comments about EmbedPreparedStatement,
probably because I in fact "cowboy-programmed" it (just searched for PreparedStatement.java
in fact.

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.
