SQL插入并选择语法

Question

我要使用MySQL，“插入”具有特定值的表，该值必须在与另一个表中的ID相等的ID之间进行选择。

我需要做类似的事情：

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语法：

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]

也许是这样的：

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";
