    Description

      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.
