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 Thu, 15 May 2008 16:29:55 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12597182#action_12597182
] 

Daniel John Debrunner commented on DERBY-3676:
----------------------------------------------

FYI - the output of toString() represents the identifier of the compiled plan. It can be used
in a query against the virtual table that represents the statement cache. Changing it would
affect backwards compatibility and make it harder to see if the statement in use is in the
statement cache.

> 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.
