从select语句向表中插入数据

Question

我在两个表（人）和（付款）工作.payments表包含列（payment_id，payment_value，payment_class，日期，名称，person_id）现在我想通过从人员表中选择来插入数据到付款

insert into Payments(payment_id , payment_value , payment_class , date , name , person_id)
select person_id , person_name , person_status from Persons where person_status = 'sub'

如何向从人员表中选择的每个人插入付款..

Answer 1

根据您的要求，以下查询为每个人插入一张记录，其中当前日期和所有其他列在表格付款中为空

INSERT INTO Payments (payment_id,payment_value,payment_class,date,name,person_id)
SELECT NULL, NULL, NULL, GETDATE(), NULL, NULL
FROM Persons
WHERE person_status = 'sub';

如果你想直接从桌面人物中提取person_id，你可以这样做：

INSERT INTO Payments (payment_id,payment_value,payment_class,date,name,person_id)
SELECT NULL, NULL, NULL, GETDATE(), NULL, person_id
FROM Persons
WHERE person_status = 'sub';
