This getBytes method is specified by the getBytes method in the java.sql.Blob interface.
If you have a null or zero length BLOB, and try to get exactly zero bytes at position 1, an empty byte array is returned (byte array of length 0).
If you have a null or zero length BLOB, and try to get any length of bytes at a position other than 1, a position exception will be thrown.
