Hi Chuck,
Ops I knew I forgot to mention something. It is supposed to be in
Hex looking like 0x000081618cb5000007d302000000011696cb1cdd430dea9f.

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);
Regardds,
Jeff
