Re: SQL update/insert for a string contain " ' "

 Weining:
 You should use two single quote instead of a double quote. .replace() will
not work. But the preparedStatement is a better way to do this. See Fred
Kulack' post for details. Basically it is like this:

 pstmt = conn.prepareStatement(" UPDATE BRUCELIB.LIBLIST SET ODLBNM = ?
WHERE ODOBNM = 'ALLYO'");
 String desc = "Tom' desk";
 pstmt.setString(1, desc);
 pstmt.executeUpdate();
