Hello,

All of the Entities in our model use primary keys that have an external data type of binary with a width of 24. I have to use some raw SQL to write some queries...One of those raw SQL queries fetches the primary key of a row. I then need to use that primary key to form the basis of another raw SQL query. I save that primary key into a NSData object. The problem is I can't seem to convert that object into a format that is can be used in another query. When I try to print the information out it doesn't look right to the eye. Anyone have anything idea's on how I might do this?

i.e

String sqlString = "SELECT contest_id FROM \"cms\". \"ms_contest\" WHERE contest_event = '" + contest.contestEvent() +"'";

NSArray result = EOUtilities.rawRowsForSQL(ec, "cms", sqlString);

        NSDictionary dict = (NSDictionary)result.objectAtIndex(0);

        NSData data = (NSData)dict.objectForKey("CONTEST_ID");

        logger.debug("Contest ID: " + data);
