postgresql - 错误 : cannot insert multiple commands into a prepared statement

Question

我正在尝试将一行从一张表移动到另一张表。

问题是，如果我将两个查询放在一起，我会得到“错误:无法将多个命令插入准备好的语句”。我能做什么？

exports.deletePost = function(id) {
    return db.query(`INSERT INTO deletedjobs
    SELECT *
    FROM jobs
    WHERE id = $1;

    DELETE FROM jobs WHERE id = $1;`, [id]).then(results => {
        console.log("succesfull transfer");
        return results.rows[0];
    });
};

编辑:关注Docs v7.0.0，我发现 db.multi 可以执行多查询字符串，你可以试试这个:

db.multi(`INSERT INTO deletedjobs
    SELECT *
    FROM jobs
    WHERE id = $1;DELETE FROM jobs WHERE id = $1`, [id])

我认为更好的解决方案是将查询包装到一个同时用于插入-删除的函数中，如下所示:

CREATE FUNCTION moveJob(id character varying) RETURNs void AS
$BODY$
BEGIN
    INSERT INTO deletedjobs
    SELECT *
    FROM jobs
    WHERE id = id;

    DELETE FROM jobs WHERE id = id;
END;
$BODY$
  LANGUAGE plpgsql VOLATILE SECURITY DEFINER
  COST 100;

并在你的 js 中调用它作为 postgresql 函数:

db.any('select moveJob($1)', [id]);
