java中try catch finally的配合使用案例

    try {
      sqls = "select syqyid,syqymc from z_syqybm  where syqyid='" + pSYQYID + "'";
      rs = db.executeQueryXZH(conn, sqls);
      if (rs.next()) {
        rssyqymc = rs.getString("syqymc");
      }
      else {
        //out.println("<script language=javascript>alert('請您先去填寫企業基本資料！');javascript:history.back();</script>");
        //out.println("<script language=javascript>alert('沒有該企業！');javascript:history.back();</script>");
      }
    }
    catch (Exception ex) {
      System.out.println("單位企業出錯:" + ex.getMessage());
    }
    finally {
      try {
            rs.close();
          }
           catch (SQLException ex1) {
      }
    }
