> By default, Sybase silently truncates a string which is longer than the column length
without raising an exception. To override this behavior, string_rtruncation must be set on.
In order to be consistent with other databases (which raise exceptions when a string length
is longer than the column length), we will set string_rtruncation on by default for Sybase.
For an application that wants to keep Sybase silent truncation behavior, a DBDictionary property
"setStringRightTruncationOn" is introduced. When it is set to false in the persistence.xml,
the string will be silently truncated during insert/update.
