Put CLOB field last when inserting a row.

When database encoding is UTF8, and you are inserting a CLOB value that is not
the last one in the field list, you can get the oracle error:

    ORA-24816: Expanded non LONG bind data supplied after actual
    LONG or LOB column

If you put the field last in the list, the error stops.  Fix found here:
