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 15:36:55 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598328#action_12598328

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

1. Also, If I understand correctly, you are saying there's no way to expose this info if runnning
the client driver (I guess that makes some sense sadly, the info would be on the server side)?


2. And if it were moved to EmbeddedDriver, how would one make it thread safe (before I was
following the other methods in the class and syncing on connection)? I mean those are ugly
public thingies? I know a Connection isn't thread safe by JDBC, and I guess that implies PreparedStatements
aren't either, too though. But assumedly there was good reason for syncing on Connection?
Or was this an abortive attempt to achieve a thread-safe driver?

> 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.
