SQL插入並選擇語法

Question

使用MySQL，我想“插入”具有特定值的表，該值必須在與另一個表中的ID相等的ID之間進行選擇。

我需要做類似的事情：

insert into activity (date_created, action, source) values ("2018-12-05 07:00:00", "UNSUBSCRIBE", "MIGRATE") where activity.customer_id = (select customer.id from customer where customer.cell_phone_number = "123456");

Answer 1

您可以使用INSERT ... SELECT語法：

INSERT [LOW_PRIORITY | HIGH_PRIORITY] [IGNORE]
    [INTO] tbl_name
    [PARTITION (partition_name [, partition_name] ...)]
    [(col_name [, col_name] ...)]
    SELECT ...
    [ON DUPLICATE KEY UPDATE assignment_list]

也許是這樣的：

INSERT INTO activity (date_created, action, source, customer_id) 
SELECT "2018-12-05 07:00:00" AS date_created, "UNSUBSCRIBE" AS action, "MIGRATE" AS source, id
FROM customer
WHERE cell_phone_number = "123456";
