我在Oracle里创建了一个会话级的临时表,用Java代码获得一个数据连接,代码如下: public Connection getConnection() throws Exception {
        Connection conn = null;
        Context ctx = new InitialContext();
        try {
            if (appKey != null) {
                ds = (DataSource) ctx.lookup(ERPJNDI); // java:comp/env/jdbc/sce
            }
            if (ds == null) {
                throw new Exception(
                        "SCEHelper can't find the datasource for SCE Database. " +
                        "Please check the System Property");
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }        try {
            if (ds != null) {
                conn = ds.getConnection();
            } else {
                throw new Exception(
                        "SCEHelper can't find the datasource for SCE Database. " +
                        "Please check the System Property");
            }        } catch (Exception ex) {
            System.out.println(
                    "/***********************************************");
            System.out.println(
                    "                                        +        ");
            System.out.println(
                    "        Connection Error !!                     ");
            System.out.println(ex.toString() +
                               "                                                ");
            System.out.println(
                    "************************************************/");
            throw ex;
        }
        return conn;
    }
然后在其他代码中调用调用了那个临时表,取出运算后的数据,并且关闭连接,怎么我下次再运行程序的时候,原来临时表中的数据怎么还在啊。怎么会话级临时表的数据在连接断开后不会自动清除啊!
