Question

我正在运行一个postgres查询，该查询调用一个函数来使用新记录更新数据库。我碰巧在这里收到错误：missing FROM-clause entry for table "create_trans"

createTransaction: function(id, sub_id, purchase_date, expiry, is_paid, latest_receipt, success, fail){
    db.query("select create_trans  ( $1, $2, to_timestamp($3), to_timestamp($4), $5, $6 )",
            [id, subscription_id, purchase_date, expiry, is_paid, latest_receipt])
        .then(success, fail)
},

上述查询函数调用postgres create_trans函数。

CREATE FUNCTION create_trans(transaction_id BIGINT, subscription_id BIGINT,purchase_date TIMESTAMPTZ, expiry TIMESTAMPTZ, is_paid BOOLEAN,latest_receipt TEXT ) RETURNS VOID AS
$$
BEGIN
    INSERT INTO transactions ( id, subscription_id, purchase_date, expiry, is_paid, latest_receipt ) VALUES ( create_trans.transaction_id, create_trans.subscription_id, create_trans.original_purchase_date, create_trans.expiry, create_trans.is_paid, create_trans.latest_receipt );
    UPDATE subscriptions SET updated_at = NOW(), expiry = create_trans.expiry, latest_receipt = create_trans.latest_receipt WHERE id = subscription_id;
    RETURN;
END;
$$
LANGUAGE plpgsql;

我最终收到此错误消息：

error: missing FROM-clause entry for table "create_trans"

知道为什么吗？

更新我更新了create_trans函数的参数，使其与列名不同。

CREATE FUNCTION create_trans(p_transaction_id BIGINT, p_subscription_id BIGINT, p_purchase_date TIMESTAMPTZ, p_expiry TIMESTAMPTZ, p_is_paid BOOLEAN,p_latest_receipt TEXT ) RETURNS VOID AS
$$
BEGIN
    INSERT INTO transactions ( id, subscription_id, purchase_date, expiry, is_paid, latest_receipt ) VALUES ( p_transaction_id, p_subscription_id, p_original_purchase_date, p_expiry, p_is_paid, p_latest_receipt );
    UPDATE subscriptions SET updated_at = NOW(), expiry = p_expiry, latest_receipt = p_latest_receipt WHERE id = p_subscription_id;
    RETURN;
END;
$$
LANGUAGE plpgsql;

我仍然收到此错误消息：

错误：缺少表的FROM子句条目 - Postgresql函数
