> Hi all, 
> I am using the version 2.3.1-SNAPSHOT in my code and I found the following bug:
> I have a datatable with 3 data fields (Integer, String and BLOB).
> The database is created correctly with different data types, but when I am trying to
get the information from the datatable executing commands, the following error is returned:
> 140 [main] INFO org.apache.empire.exceptions.EmpireException - An Error occured. Message
is: The database operation failed. Native error is: Bad value for type long : \x01000100
> The code I am using is the following (the BLOB data tye field is called "Information"):
> /**
> 	 * Gets the address books.
> 	 *
> 	 * @return the address books
> 	 */
> 	public List<addressBookBean> getAddressBooks(){
> 		List<addressBookBean> myABs = new ArrayList<addressBookBean>();
> 				
> 		DBCommand cmd = db.createCommand();
> 		cmd.select(db.ADDRESSBOOK.ADDRESS_BOOK_ID, db.ADDRESSBOOK.LOCATION, db.ADDRESSBOOK.INFORMATION);
> 		
> 		DBReader reader = new DBReader();
> 		reader.open(cmd, conn);
> 		while(reader.moveNext()){
> 			myABs.add(new addressBookBean(
> 					reader.getInt(db.ADDRESSBOOK.ADDRESS_BOOK_ID),
> 					reader.getString(db.ADDRESSBOOK.LOCATION), 
> 					(byte[]) reader.getValue(db.ADDRESSBOOK.INFORMATION)));
> 		}
> 		
> 		return myABs;
> 	}
> Thanks a lot for your time and if any further information is required, don't hesitate
and let me know.
> Best Regards,
> Jon
> PS: I opened an issue about a bug with the BLOB data type when the sql script is generated
for creating the database. the error message was very similar and it was totally fixed. Maybe
it can help. The issue is the following:
