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 Wed, 17 Aug 2011 19:51:28 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13086548#comment-13086548
] 

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.

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.
