如何在不指定列名的情况下使用jdbcTemplate更新整个对象？

Question

I was looking at the reference here . We can do this -

String orderSql = "select * from order where id = ?"; jdbcTemplate.query(orderSql, new BeanPropertyRowMapper<>(Order.class), orderId);

This reads from the database and can directly deserialise into the Order object. This is well and good.

What I want to do is -

String updateSql = "update order ? where id = ?"; jdbcTemplate.save(updateSql, new BeanPropertyRowMapper<>(Order.class), order, orderId);

Is there a way of doing this?

Answer 1

No, it's not possible. JdbcTemplate comes with the ability to map an object using query as you've said without having to define columns/attributes, but there is no equivalent usage for update . You will have to pass in your SQL and the relevant parameters. As someone has mentioned if you really want to do this you could consider using hibernate.

Answer 2

No ! You can only do this !

jdbcTemplate.update("update ordertable set order = ? where id = ?", order, orderId);

Answer 3

Use this query for update :-

String updateSql = "update <table_name> set order= ? where id = ?";

jdbcTemplate.update(updateSql, new Object[]{order, orderId});

It will return affected row update count.
