I'm using PreparedStatements, so that is not an issue. The issue is that I can't query for Timestamp equality as shown below.

Apparently, the TIMESTAMP column type in MySQL does not record milliseconds. Therefore it is not all the compatible with the java.sql.Timestamp class. For instance:
Timestamp stamp = new Timestamp( System.currentTimeMillis() );
// write record with this....
// search record for field with value = stamp
// no results! :(
Does anyone have a general pattern for dealing with this? Across database implementations? I suppose the easiest thing is to never use timestamp directly and create methods called #getTime and #getTimestamp something like this?
Robert,
You need to zero-out the nanos if you're not using prepared statements by calling Timestamp.setNanos(int). Are you using prepared statments (where this is taken care of for you), or are you generating plain statements on the fly?
