Oracle表格字段采用sequence进行自增长时,采用Dbutils进行insert或update数据时的处理技巧

// 定义插入记录的方法
    public Teacher insert(String name, String gender, Double score) {
        // 获得连接
        Connection conn = JDBCUtil.getConnection();
        // 建立QueryRunner类的对象,切记此处,应当设置为true
        QueryRunner qr = new QueryRunner(true);
        String sql = "insert into teacher values(t.nextval,?,?,?)";
        String sql1 = "select t.currval from teacher";
        Object[] params = {name, gender, score};
        Teacher b = null;
        try {
            b = qr.insert(conn, sql, new BeanHandler<Teacher>(Teacher.class), params);

        } catch (SQLException e) {
            e.printStackTrace();
        }
        return b;
    }
